matchMethodInvocation
public Description matchMethodInvocation(com.sun.source.tree.MethodInvocationTree tree, VisitorState state)
Matches if a long or Long is converted to an int for a long parameter in a method invocation.Does **not** match if the method parameter is a Long, because passing an int or Integer for a Long parameter produces an incompatible types error. Does **not** match when a long or Long is converted to an Integer because this requires first converting to an int and then to an Integer. This is awkwardly complex and out of scope. Does **not** match when the conversion occurs in a separate statement prior the method invocation.
