Examples of java.nio.ByteBuffer.arrayOffset()

java.nio.ByteBuffer.arrayOffset()
Returns the offset of the byte array which this buffer is based on, if there's one.
The offset is the index of the array corresponds to the zero position of the buffer.
@return The offset of the byte array which this buffer is based on @exception ReadOnlyBufferException If this buffer is based on a readonly array @exception UnsupportedOperationException If this buffer is not based on an array
