Method Detail

newByteBuffer

public static ByteBuffer newByteBuffer(int numElements)

Allocates a new direct ByteBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

newDoubleBuffer

public static DoubleBuffer newDoubleBuffer(int numElements)

Allocates a new direct DoubleBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

newFloatBuffer

public static FloatBuffer newFloatBuffer(int numElements)

Allocates a new direct FloatBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

newIntBuffer

public static IntBuffer newIntBuffer(int numElements)

Allocates a new direct IntBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

newLongBuffer

public static LongBuffer newLongBuffer(int numElements)

Allocates a new direct LongBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

newShortBuffer

public static ShortBuffer newShortBuffer(int numElements)

Allocates a new direct ShortBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

copyByteBuffer

public static ByteBuffer copyByteBuffer(ByteBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed ByteBuffer into a newly-allocated direct ByteBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyDoubleBuffer

public static DoubleBuffer copyDoubleBuffer(DoubleBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed DoubleBuffer into a newly-allocated direct DoubleBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyFloatBuffer

public static FloatBuffer copyFloatBuffer(FloatBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed FloatBuffer into a newly-allocated direct FloatBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyIntBuffer

public static IntBuffer copyIntBuffer(IntBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed IntBuffer into a newly-allocated direct IntBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyLongBuffer

public static LongBuffer copyLongBuffer(LongBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed LongBuffer into a newly-allocated direct LongBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyShortBuffer

public static ShortBuffer copyShortBuffer(ShortBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed ShortBuffer into a newly-allocated direct ShortBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyDoubleBufferAsByteBuffer

public static ByteBuffer copyDoubleBufferAsByteBuffer(DoubleBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed DoubleBuffer into a newly-allocated direct ByteBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyFloatBufferAsByteBuffer

public static ByteBuffer copyFloatBufferAsByteBuffer(FloatBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed FloatBuffer into a newly-allocated direct ByteBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyIntBufferAsByteBuffer

public static ByteBuffer copyIntBufferAsByteBuffer(IntBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed IntBuffer into a newly-allocated direct ByteBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyLongBufferAsByteBuffer

public static ByteBuffer copyLongBufferAsByteBuffer(LongBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed LongBuffer into a newly-allocated direct ByteBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

copyShortBufferAsByteBuffer

public static ByteBuffer copyShortBufferAsByteBuffer(ShortBuffer orig)

Copies the remaining elements (as defined by limit() - position()) in the passed ShortBuffer into a newly-allocated direct ByteBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).
