public boolean matches(Object item)
Matcher
This method matches against Object, instead of the generic type T. This is because the caller of the Matcher does not know at runtime what the type is (because of type erasure with Java generics). It is down to the implementations to check the correct type.
item
- the object against which the matcher is evaluated.
true
if item matches, otherwise false
