Description

The list of methods to do FloatBuffer Copy are organized into topic(s).

Method

void copy(final FloatBuffer source, final int fromPos, final FloatBuffer destination, final int toPos, final int length)
Copies floats from one buffer to another.

final int oldLimit = source.limit();
source.position(fromPos);
source.limit(fromPos + length);
destination.position(toPos);
destination.put(source);
source.limit(oldLimit);

void copy(float[] vertices, FloatBuffer floatBuffer, int numFloats, int offset)
copy

floatBuffer.position(0);
floatBuffer.limit(numFloats);
for (int index = 0; index < numFloats; index++)
 floatBuffer.put(vertices[index + offset]);
floatBuffer.position(0);

FloatBuffer copyFloatBuffer(FloatBuffer buf)
copy Float Buffer

return copyFloatBufferAsByteBuffer(buf).asFloatBuffer();

void copyInternal(FloatBuffer buf, int fromPos, int toPos, int length)
Copies floats from one position in the buffer to another.

float[] data = new float[length];
buf.position(fromPos);
buf.get(data);
buf.position(toPos);
buf.put(data);

void copyInternalVector2(final FloatBuffer buf, final int fromPos, final int toPos)
copy Internal Vector

copyInternal(buf, fromPos * 2, toPos * 2, 2);

void copyInternalVector3(FloatBuffer buf, int fromPos, int toPos)
Copies a Vector3f from one position in the buffer to another.

copyInternal(buf, fromPos * 3, toPos * 3, 3);
