the class PacketIOHelperTest method cloningOfPacket.

/**
 * Verifies that writing a Packet to a ByteBuffer and then reading it from the ByteBuffer, gives the same Packet (content).
 */

    assertPacketEquals(originalPacket, clonedPacket);
}

Example 48 with Packet

use of com.hazelcast.internal.nio.Packet in project hazelcast by hazelcast.

the class PacketIOHelperTest method largeValue.

/**
 * Checks if the packet can deal with a buffer that is very small, but the data is very large, which
 * needs repeated calls to {@link PacketIOHelper#writeTo(Packet, ByteBuffer)} and
 * {@link PacketIOHelper#readFrom(ByteBuffer)}.
 */
@Test
