LongBuffer asReadOnlyBuffer() method in Java
The asReadOnlyBuffer() method of java.nio.LongBuffer Class is used to create a new, read-only Long buffer with this buffer’s content. The new buffer is a replica of this buffer. Hence changes made to this buffer’s content will be visible in the new buffer.
Since the new buffer is read-only, therefore any modification to its content won’t be allowed. The two buffers’ position, limit, and mark values will be independent. The new buffer’s capacity, limit, position, and mark values will be identical to those of this buffer. If this buffer is itself read-only then this method behaves in exactly the same way as the duplicate method.
public abstract LongBuffer asReadOnlyBuffer()
Return Value: This method returns the new, read-only Long buffer with the same content as that of this buffer.
Below are the examples to illustrate the asReadOnlyBuffer() method:
Original LongBuffer: [8, 0, 9, 0, 0, 0, 0, 0, 0, 0] ReadOnlyBuffer LongBuffer: 8, 0, 9, 0, 0, 0, 0, 0, 0, 0,
LongBuffer ib: [8, 0, 9, 0, 0, 0, 0, 0, 0, 0] LongBuffer ib1: [0, 4, 6, 0, 0] ReadOnlyBuffer LongBuffer: 8, 0, 9, 0, 0, 0, 0, 0, 0, 0, Trying to get the array from ReadOnlyib for editing
