Method Detail

matches

public boolean matches(java.lang.Object argument,
                       java.lang.Object argumentAtInvocationTime)

Returns true if the given object is not null, false otherwise. The argumentAtInvocationTime is a copy (deep clone) of the arguments at the time of the invocation. This way the original values can still be used later-on even when changes occur to the original values (pass-by-value vs pass-by-reference).

Specified by:

matches in interface ArgumentMatcher

Parameters:

argument - The argument that were used by reference, not null

argumentAtInvocationTime - Copy of the argument, taken at the time that the invocation was performed, not null

Returns:

True when passed object matches, false otherwise.
