public void setForgetOnLoad (boolean forget)

Get the number of bytes use for each value in the buffer.
This size is derivate from the gpu data type;
return number of byte per value. 0 is data buffer has not been set

public int getBytePerElement ()

Get number of tuples.
size / tupleSize
return number of tuples.

public int getTupleCount ()

Get primitive buffer.
Can be null.
return Buffer or null if not loaded on system memory

public Buffer getPrimitiveBuffer ()

Get a single tuple at index.
param  index tuple index
param  buffer optional buffer
return  tuple

public int[] getTupleInt (int index, int[] buffer)

Get a single tuple at index.
param  index tuple index
param  buffer optional buffer
return  tuple

public float[] getTupleFloat (int index, float[] buffer)

Set a single tuple at index.
param index tuple index
param buffer tuple data

public void setTupleInt (int index, int[] buffer)

Set a single tuple at index.
param index tuple index
param buffer tuple data

public void setTupleFloat (int index, float[] buffer)

Indicate if the system data buffer values has been changed.
return true if datas has been changed compared to the last time
they were loaded on the gpu.

public boolean isDirty ()

Declare the buffer to be dirty.
Use when direct modification are made to the buffer.
