com.jogamp.common.nio.PointerBuffer

All Implemented Interfaces:

NativeBuffer<PointerBuffer>

public class PointerBuffer
extends AbstractBuffer<PointerBuffer>

Hardware independent container for native pointer arrays. The native values (NIO direct ByteBuffer) might be 32bit or 64bit wide, depending of the CPU pointer width.

Field Detail

ELEMENT_SIZE

public static final int ELEMENT_SIZE

dataMap

protected LongObjectHashMap dataMap

Method Detail

allocate

public static PointerBuffer allocate(int size)

Returns a non direct PointerBuffer in native order, having a backup array

allocateDirect

public static PointerBuffer allocateDirect(int size)

Returns a direct PointerBuffer in native order, w/o backup array

wrap

public static PointerBuffer wrap(ByteBuffer src)

duplicate

public final PointerBuffer duplicate()

Returns:

new PointerBuffer sharing the same buffer data of this instance (identity), but having an independent position.

put

public final PointerBuffer put(PointerBuffer src)

Relative bulk get method. Copy the source values src[position .. capacity] [ to this buffer and increment the position by capacity-position.

get

public final long get()

Relative get method. Get the pointer value at the current position and increment the position by one.

get

public final long get(int idx)

Absolute get method. Get the pointer value at the given index

get

public final PointerBuffer get(long[] dest,
                               int offset,
                               int length)

Relative bulk get method. Copy the pointer values [ position .. position+length [ to the destination array [ dest[offset] .. dest[offset+length] [ and increment the position by length.

put

public final PointerBuffer put(int idx,
                               long v)

Absolute put method. Put the pointer value at the given index

put

public final PointerBuffer put(long value)

Relative put method. Put the pointer value at the current position and increment the position by one.

put

public final PointerBuffer put(long[] src,
                               int offset,
                               int length)

Relative bulk put method. Put the pointer values [ src[offset] .. src[offset+length] [ at the current position and increment the position by length.

referenceBuffer

public final PointerBuffer referenceBuffer(int index,
                                           Buffer bb)

Put the address of the given direct Buffer at the given position of this pointer array. Adding a reference of the given direct Buffer to this object.

Throws:

IllegalArgumentException - if bb is null or not a direct buffer

referenceBuffer

public final PointerBuffer referenceBuffer(Buffer bb)

Put the address of the given direct Buffer at the end of this pointer array. Adding a reference of the given direct Buffer to this object.

getReferencedBuffer

public final Buffer getReferencedBuffer(int index)

getReferencedBuffer

public final Buffer getReferencedBuffer()

toString

public String toString()

Overrides:

toString in class AbstractBuffer<PointerBuffer>
