List of addInvokevirtual() Examples

Examples of addInvokevirtual()

javassist.bytecode.Bytecode.addInvokevirtual()
Appends INVOKEVIRTUAL.
The specified method must not be an inherited method. It must be directly declared in the class specified in clazz. @param clazz the target class. @param name the method name @param returnType the return type. @param paramTypes the parameter types.
