List of Checksum() Examples

Examples of Checksum()

flex2.compiler.CompilerSwcContext.checksum()
kafka.message.Message.checksum()
org.elasticsearch.index.store.StoreFileMetaData.checksum()
org.gdal.gdal.Band.Checksum()
org.jnetpcap.protocol.network.Icmp.checksum()
Retrieves the header's checksum. @return header's stored checksum
org.jnetpcap.protocol.network.Ip4.checksum()
Retrieves the header's checksum. @return header's stored checksum
org.jnetpcap.protocol.tcpip.Tcp.checksum()
Checksum (16 bits). The 16-bit checksum field is used for error-checking of the header and data . @return the field's value

Examples of org.jnetpcap.protocol.network.Ip4.checksum()

    assertEquals(3, icmp.type());
    assertEquals(3, icmp.code());
    assertEquals(0x2731, icmp.checksum());
    assertEquals(0, unreach.reserved());


    assertEquals(0x8724, ip.checksum());
    assertEquals(440, ip.length());


    // Devil's advocate
    assertFalse(icmp.hasSubHeader(IcmpType.ECHO_REPLY.getId()));
    assertFalse(icmp.hasSubHeader(IcmpType.PARAM_PROBLEM.getId()));
