Field Detail
-
isInterface
protected final boolean isInterface
Whether the visited signature is a class signature of a Java interface.
-
declaration
protected final java.lang.StringBuilder declaration
The Java generic type declaration corresponding to the visited signature.
-
argumentStack
protected int argumentStack
The stack used to keep track of class types that have arguments. Each element of this stack is a boolean encoded in one bit. The top of the stack is the least significant bit. Pushing false = *2, pushing true = *2+1, popping = /2.
