public class Topology

extends java.lang.Object

This class allow to the programmer specify all the topologies of the networks. Actually only exists three topologies:

• RANDOM ("Random"): Where the Id of nodes are distributed randomly.
• CIRCULAR ("Circular"): Where the Id of nodes are distributed uniformly.
• SERIALIZED ("Serialized"): Where the entire ring are restored from serialized state file.

Method Detail

isValid

public static boolean isValid(java.lang.String topology)

Identify if the topology specified is valid or not.

Parameters:

topology - Topology to test if is valid.

Returns:

true if topology is valid. false in another case.

isValidForNew

public static boolean isValidForNew(java.lang.String topology)

Inform when the specified topology is valid to build new instances with sentence new. Actually, only the SERIALIZED topology is not valid.

Parameters:

topology - Topology to test.

Returns:

true if the topology is RANDOM or CIRCULAR. false in other case.
