public ShortBuffer put(ShortBuffer src) 

Source Link

Document

Writes all the remaining shorts of the src short buffer to this buffer's current position, and increases both buffers' position by the number of shorts copied.

Usage

From source file:Main.java

public static ShortBuffer createShortBuffer(short[] data) {
    ShortBuffer sb = ByteBuffer.allocateDirect(data.length * BYTES_PER_SHORT).order(ByteOrder.nativeOrder())
            .asShortBuffer();//  ww w.  ja  v  a 2s  .c  o m
    sb.put(data).position(0);
    return sb;
}
