Class PointerBuffer

java.lang.Object
com.jogamp.common.nio.AbstractBuffer<PointerBuffer>
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 Details

    • ELEMENT_SIZE

      public static final int ELEMENT_SIZE

    • dataMap

      protected LongObjectHashMap dataMap

  • Method Details

    • 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>
