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

org.jnetpcap.protocol.network.Ip4.source()
Converts the 32 bit Ip4 source address to a java signed 32 bit integer. The value returned should be treated as an unsigned integer, which java can not represent as an int. If neccessary to printout the value returned, in order to correctly represent the unsinged value, the integer returned should be converted to a java long type and sign appropriately handled to take advantage of the extra length of a java long type. @return unsinged 32 bit integer representing the Ip4 source address
