Examples of java.nio.DoubleBuffer

java.nio.DoubleBuffer
A buffer of doubles.
A double buffer can be created in either of the following ways:
- {@link #allocate(int) Allocate} a new double array and create a bufferbased on it;
- {@link #wrap(double[]) Wrap} an existing double array to create a newbuffer;
- Use {@link java.nio.ByteBuffer#asDoubleBuffer() ByteBuffer.asDoubleBuffer} tocreate a double buffer based on a byte buffer.
