Class IntArrayBuffer

java.lang.Object
  java.nio.Buffer
      java.nio.IntBuffer
          java.nio.IntArrayBuffer

All Implemented Interfaces:

Comparable<IntBuffer>

Direct Known Subclasses:

ReadOnlyIntArrayBuffer, ReadWriteIntArrayBuffer

abstract class IntArrayBuffer
extends IntBuffer

IntArrayBuffer, ReadWriteIntArrayBuffer and ReadOnlyIntArrayBuffer compose the implementation of array based int buffers.

IntArrayBuffer implements all the shared readonly methods and is extended by the other two classes.

All methods are marked final for runtime performance.

Field Summary

IntArrayBuffer(int capacity, int[] backingArray, int offset)

Method Summary

int	get() Returns the int at the current position and increase the position by 1.
int	get(int index) Returns a int at the specified index, and the position is not changed.
IntBuffer	get(int[] dest, int off, int len) Reads ints from the current position into the specified int array, starting from the specified offset, and increase the position by the number of ints read.
boolean	isDirect() Returns true if this buffer is direct.
ByteOrder	order() Returns the byte order used by this buffer when converting ints from/to bytes.

Method Detail

get

public final int get()

Description copied from class: IntBuffer

Returns the int at the current position and increase the position by 1.

Specified by:

get in class IntBuffer

Returns:

The int at the current position.

get

public final int get(int index)

Description copied from class: IntBuffer

Returns a int at the specified index, and the position is not changed.

Specified by:

get in class IntBuffer

Parameters:

index - The index, must be no less than zero and less than limit

Returns:

A int at the specified index.

get

public final IntBuffer get(int[] dest,
                           int off,
                           int len)

Description copied from class: IntBuffer

Reads ints from the current position into the specified int array, starting from the specified offset, and increase the position by the number of ints read.

Overrides:

get in class IntBuffer

Parameters:

dest - The target int array

off - The offset of the int array, must be no less than zero and no greater than dest.length

len - The number of ints to read, must be no less than zero and no greater than dest.length - off

Returns:

This buffer

isDirect

public final boolean isDirect()

Description copied from class: IntBuffer

Returns true if this buffer is direct.

A int buffer is direct, if it is based on a byte buffer and the byte buffer is direct.

Specified by:

isDirect in class IntBuffer

Returns:

True if this buffer is direct.

order

public final ByteOrder order()

Description copied from class: IntBuffer

Returns the byte order used by this buffer when converting ints from/to bytes.

If this buffer is not based on a byte buffer, then always return the platform's native byte order.

Specified by:

order in class IntBuffer

Returns:

The byte order used by this buffer when converting ints from/to bytes.
