Enum Tcp.AlternateChecksumRequest.Algorithm

java.lang.Object
  java.lang.Enum<Tcp.AlternateChecksumRequest.Algorithm>
      org.jnetpcap.protocol.tcpip.Tcp.AlternateChecksumRequest.Algorithm

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Tcp.AlternateChecksumRequest.Algorithm>

Enclosing class:

Tcp.AlternateChecksumRequest

public static enum Tcp.AlternateChecksumRequest.Algorithm
extends java.lang.Enum<Tcp.AlternateChecksumRequest.Algorithm>

A SYN segment used to originate a connection may contain the Alternate Checksum Request Option, which specifies an alternate checksum-calculation algorithm to be used for the connection. The acknowledging SYN-ACK segment may also carry the option.

Field Detail

type

public final int type

Numerical type for this algorithm constant.

Method Detail

values

public static Tcp.AlternateChecksumRequest.Algorithm[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Tcp.AlternateChecksumRequest.Algorithm c : Tcp.AlternateChecksumRequest.Algorithm.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Tcp.AlternateChecksumRequest.Algorithm valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

valueOf

public static Tcp.AlternateChecksumRequest.Algorithm valueOf(int type)

Converts a numerical algorithm type to enum constant.

Parameters:

type - numerical type

Returns:

enum constant type
