Method Detail

isA

public static boolean isA(TypeNode n,
                          java.lang.String clazzName)

Checks whether the resolved type of the given TypeNode n is of the type given by the clazzName. If the clazzName is on the auxclasspath, then also subclasses are considered.

Parameters:

n - the type node to check

clazzName - the class name to compare to

Returns:

true if type node n is of type clazzName or a subtype of clazzName
