Examples of java.nio.ByteBuffer.asLongBuffer()

java.nio.ByteBuffer.asLongBuffer()
Returns a long buffer which is based on the remaining content of this byte buffer.
The new buffer's position is zero, its limit and capacity is the number of remaining bytes divided by two, and its mark is not set. The new buffer's readonly property and byte order are same as this buffer. The new buffer is direct, if this byte buffer is direct.

The new buffer shares content with this buffer, which means either buffer's change of content will be visible to the other. The two buffer's position, limit and mark are independent.
@return A long buffer which is based on the content ofthis byte buffer.
