Examples of org.apache.mina.core.buffer.IoBuffer.sweep()

org.apache.mina.core.buffer.IoBuffer.sweep()
Clears this buffer and fills its content with NUL. The position is set to zero, the limit is set to the capacity, and the mark is discarded.

        // Expand the buffer.
        buf.capacity(32).clear();
        assertEquals(32, buf.capacity());


        // Make sure the buffer shrinks when only 1/8 is being used.
        buf.sweep((byte) 1);
        buf.fill(28);
        buf.compact();
        assertEquals(8, buf.capacity());
        assertEquals(4, buf.position());
        assertEquals(8, buf.limit());
