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
