Examples of java.nio.ShortBuffer

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