allocate

open static fun allocate(capacity: Int): ShortBuffer!

Allocates a new short buffer.

The new buffer's position will be zero, its limit will be its capacity, its mark will be undefined, each of its elements will be initialized to zero, and its byte order will be the native order of the underlying hardware. It will have a backing array, and its array offset will be zero.

array

fun array(): ShortArray!

Returns the short array that backs this buffer  (optional operation).

Modifications to this buffer's content will cause the returned array's content to be modified, and vice versa.

Invoke the hasArray method before invoking this method in order to ensure that this buffer has an accessible backing array.

arrayOffset

fun arrayOffset(): Int

Returns the offset within this buffer's backing array of the first element of the buffer  (optional operation).

If this buffer is backed by an array then buffer position p corresponds to array index p + arrayOffset().

Invoke the hasArray method before invoking this method in order to ensure that this buffer has an accessible backing array.

asReadOnlyBuffer

abstract fun asReadOnlyBuffer(): ShortBuffer!

Creates a new, read-only short buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer; the new buffer itself, however, will be read-only and will not allow the shared content to be modified. The two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, mark values, and byte order will be identical to those of this buffer.

If this buffer is itself read-only then this method behaves in exactly the same way as the duplicate method.

clear

open fun clear(): Buffer!

Clears this buffer. The position is set to zero, the limit is set to the capacity, and the mark is discarded.

Invoke this method before using a sequence of channel-read or put operations to fill this buffer. For example:

buf.clear();     // Prepare buffer for reading
  in.read(buf);    // Read data

This method does not actually erase the data in the buffer, but it is named as if it did because it will most often be used in situations in which that might as well be the case.

compact

abstract fun compact(): ShortBuffer!

Compacts this buffer  (optional operation).

The shorts between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the short at index p = position() is copied to index zero, the short at index p + 1 is copied to index one, and so forth until the short at index limit() - 1 is copied to index n = limit() - 1 - p. The buffer's position is then set to n+1 and its limit is set to its capacity. The mark, if defined, is discarded.

The buffer's position is set to the number of shorts copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.

compareTo

open fun compareTo(other: ShortBuffer!): Int

Compares this buffer to another.

Two short buffers are compared by comparing their sequences of remaining elements lexicographically, without regard to the starting position of each sequence within its corresponding buffer. Pairs of short elements are compared as if by invoking Short#compare(short,short).

A short buffer is not comparable to any other type of object.

duplicate

abstract fun duplicate(): ShortBuffer!

Creates a new short buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, mark values, and byte order will be identical to those of this buffer. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

equals

open fun equals(other: Any?): Boolean

Tells whether or not this buffer is equal to another object.

Two short buffers are equal if, and only if,

1. They have the same element type,
2. They have the same number of remaining elements, and
3. The two sequences of remaining elements, considered independently of their starting positions, are pointwise equal.

A short buffer is not equal to any other type of object.

flip

open fun flip(): Buffer!

Flips this buffer. The limit is set to the current position and then the position is set to zero. If the mark is defined then it is discarded.

After a sequence of channel-read or put operations, invoke this method to prepare for a sequence of channel-write or relative get operations. For example:

buf.put(magic);    // Prepend header
  in.read(buf);      // Read data into rest of buffer
  buf.flip();        // Flip buffer
  out.write(buf);    // Write header + data to channel

This method is often used in conjunction with the compact method when transferring data from one place to another.

get

abstract fun get(): Short

Relative get method. Reads the short at this buffer's current position, and then increments the position.

get

abstract fun get(index: Int): Short

Absolute get method. Reads the short at the given index.

get

open fun get(
    dst: ShortArray!, 
    offset: Int, 
    length: Int
): ShortBuffer!

Relative bulk get method.

This method transfers shorts from this buffer into the given destination array. If there are fewer shorts remaining in the buffer than are required to satisfy the request, that is, if length > remaining(), then no shorts are transferred and a BufferUnderflowException is thrown.

Otherwise, this method copies length shorts from this buffer into the given array, starting at the current position of this buffer and at the given offset in the array. The position of this buffer is then incremented by length.

In other words, an invocation of this method of the form src.get(dst, off, len) has exactly the same effect as the loop

<code>for (int i = off; i &lt; off + len; i++)
          dst[i] = src.get();
  </code>

get

open fun get(dst: ShortArray!): ShortBuffer!

Relative bulk get method.

This method transfers shorts from this buffer into the given destination array. An invocation of this method of the form src.get(a) behaves in exactly the same way as the invocation

src.get(a, 0, a.length) 

get

open fun get(
    index: Int, 
    dst: ShortArray!, 
    offset: Int, 
    length: Int
): ShortBuffer!

Absolute bulk get method.

This method transfers length shorts from this buffer into the given array, starting at the given index in this buffer and at the given offset in the array. The position of this buffer is unchanged.

An invocation of this method of the form src.get(index, dst, offset, length) has exactly the same effect as the following loop except that it first checks the consistency of the supplied parameters and it is potentially much more efficient:

<code>for (int i = offset, j = index; i &lt; offset + length; i++, j++)
          dst[i] = src.get(j);
  </code>

get

open fun get(
    index: Int, 
    dst: ShortArray!
): ShortBuffer!

Absolute bulk get method.

This method transfers shorts from this buffer into the given destination array. The position of this buffer is unchanged. An invocation of this method of the form src.get(index, dst) behaves in exactly the same way as the invocation:

src.get(index, dst, 0, dst.length) 

hasArray

fun hasArray(): Boolean

Tells whether or not this buffer is backed by an accessible short array.

If this method returns true then the array and arrayOffset methods may safely be invoked.

hashCode

open fun hashCode(): Int

Returns the current hash code of this buffer.

The hash code of a short buffer depends only upon its remaining elements; that is, upon the elements from position() up to, and including, the element at limit() - 1.

Because buffer hash codes are content-dependent, it is inadvisable to use buffers as keys in hash maps or similar data structures unless it is known that their contents will not change.

isDirect

abstract fun isDirect(): Boolean

Tells whether or not this short buffer is direct.

limit

open fun limit(newLimit: Int): Buffer!

Sets this buffer's limit. If the position is larger than the new limit then it is set to the new limit. If the mark is defined and larger than the new limit then it is discarded.

mark

open fun mark(): Buffer!

Sets this buffer's mark at its position.

mismatch

open fun mismatch(that: ShortBuffer!): Int

Finds and returns the relative index of the first mismatch between this buffer and a given buffer. The index is relative to the position of each buffer and will be in the range of 0 (inclusive) up to the smaller of the remaining elements in each buffer (exclusive).

If the two buffers share a common prefix then the returned index is the length of the common prefix and it follows that there is a mismatch between the two buffers at that index within the respective buffers. If one buffer is a proper prefix of the other then the returned index is the smaller of the remaining elements in each buffer, and it follows that the index is only valid for the buffer with the larger number of remaining elements. Otherwise, there is no mismatch.

order

abstract fun order(): ByteOrder!

Retrieves this buffer's byte order.

The byte order of a short buffer created by allocation or by wrapping an existing short array is the native order of the underlying hardware. The byte order of a short buffer created as a view of a byte buffer is that of the byte buffer at the moment that the view is created.

position

open fun position(newPosition: Int): Buffer!

Sets this buffer's position. If the mark is defined and larger than the new position then it is discarded.

put

abstract fun put(s: Short): ShortBuffer!

Relative put method  (optional operation).

Writes the given short into this buffer at the current position, and then increments the position.

put

abstract fun put(
    index: Int, 
    s: Short
): ShortBuffer!

Absolute put method  (optional operation).

Writes the given short into this buffer at the given index.

put

open fun put(src: ShortBuffer!): ShortBuffer!

Relative bulk put method  (optional operation).

This method transfers the shorts remaining in the given source buffer into this buffer. If there are more shorts remaining in the source buffer than in this buffer, that is, if src.remaining() > remaining(), then no shorts are transferred and a BufferOverflowException is thrown.

Otherwise, this method copies n = src.remaining() shorts from the given buffer into this buffer, starting at each buffer's current position. The positions of both buffers are then incremented by n.

In other words, an invocation of this method of the form dst.put(src) has exactly the same effect as the loop

while (src.hasRemaining())
          dst.put(src.get()); 

put

open fun put(
    index: Int, 
    src: ShortBuffer!, 
    offset: Int, 
    length: Int
): ShortBuffer!

Absolute bulk put method  (optional operation).

This method transfers length shorts into this buffer from the given source buffer, starting at the given offset in the source buffer and the given index in this buffer. The positions of both buffers are unchanged.

In other words, an invocation of this method of the form dst.put(index, src, offset, length) has exactly the same effect as the loop

<code>for (int i = offset, j = index; i &lt; offset + length; i++, j++)
      dst.put(j, src.get(i));
  </code>

put

open fun put(
    src: ShortArray!, 
    offset: Int, 
    length: Int
): ShortBuffer!

Relative bulk put method  (optional operation).

This method transfers shorts into this buffer from the given source array. If there are more shorts to be copied from the array than remain in this buffer, that is, if length > remaining(), then no shorts are transferred and a BufferOverflowException is thrown.

Otherwise, this method copies length shorts from the given array into this buffer, starting at the given offset in the array and at the current position of this buffer. The position of this buffer is then incremented by length.

In other words, an invocation of this method of the form dst.put(src, off, len) has exactly the same effect as the loop

<code>for (int i = off; i &lt; off + len; i++)
          dst.put(src[i]);
  </code>

put

fun put(src: ShortArray!): ShortBuffer!

Relative bulk put method  (optional operation).

This method transfers the entire content of the given source short array into this buffer. An invocation of this method of the form dst.put(a) behaves in exactly the same way as the invocation

dst.put(a, 0, a.length) 

put

open fun put(
    index: Int, 
    src: ShortArray!, 
    offset: Int, 
    length: Int
): ShortBuffer!

Absolute bulk put method  (optional operation).

This method transfers length shorts from the given array, starting at the given offset in the array and at the given index in this buffer. The position of this buffer is unchanged.

An invocation of this method of the form dst.put(index, src, offset, length) has exactly the same effect as the following loop except that it first checks the consistency of the supplied parameters and it is potentially much more efficient:

<code>for (int i = offset, j = index; i &lt; offset + length; i++, j++)
          dst.put(j, src[i]);
  </code>

put

open fun put(
    index: Int, 
    src: ShortArray!
): ShortBuffer!

Absolute bulk put method  (optional operation).

This method copies shorts into this buffer from the given source array. The position of this buffer is unchanged. An invocation of this method of the form dst.put(index, src) behaves in exactly the same way as the invocation:

dst.put(index, src, 0, src.length); 

reset

open fun reset(): Buffer!

Resets this buffer's position to the previously-marked position.

Invoking this method neither changes nor discards the mark's value.

rewind

open fun rewind(): Buffer!

Rewinds this buffer. The position is set to zero and the mark is discarded.

Invoke this method before a sequence of channel-write or get operations, assuming that the limit has already been set appropriately. For example:

out.write(buf);    // Write remaining data
  buf.rewind();      // Rewind buffer
  buf.get(array);    // Copy data into array

slice

abstract fun slice(): ShortBuffer!

Creates a new short buffer whose content is a shared subsequence of this buffer's content.

The content of the new buffer will start at this buffer's current position. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's position will be zero, its capacity and its limit will be the number of shorts remaining in this buffer, its mark will be undefined, and its byte order will be identical to that of this buffer. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

slice

abstract fun slice(
    index: Int, 
    length: Int
): ShortBuffer!

Creates a new short buffer whose content is a shared subsequence of this buffer's content.

The content of the new buffer will start at position index in this buffer, and will contain length elements. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's position will be zero, its capacity and its limit will be length, its mark will be undefined, and its byte order will be identical to that of this buffer. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

toString

    array: ShortArray!, 
    offset: Int, 
    length: Int
): ShortBuffer!
