equals

public boolean equals(java.lang.Object other)

An equals method is needed if you are going to do any searching of TupleSpace for Tuples that have a match on the user object. The default Object.equals(Object 0) returns true only on for byte by byte equality which may not make sense for objects that consist of multiple data fields The following equals method determines equality by comparing the "userdata" field. The point is that for User objects, the equality is determined by the purpose and use of the object not by any predetermined Java specification. Note that it is important to protect against NullPointerExceptions

Overrides:

equals in class java.lang.Object

Parameters:

other - The value from the corresponding Field in the Tuple that we are comparing against.
