Examples of org.glassfish.grizzly.Buffer.shrink()

org.glassfish.grizzly.Buffer.shrink()
Disposes the buffer part, outside [position, limit] interval if possible. May return without changing capacity. After shrink is called, position/limit/capacity values may have different values, than before, but still point to the same Buffer elements.

                encoder.transform(connection, input);


        if (!input.hasRemaining()) {
            input.tryDispose();
        } else {
            input.shrink();
        }

            switch (result.getStatus()) {
