introduceMethod
public PlasticMethod introduceMethod(MethodDescription description)
Description copied from interface:PlasticClassReturns an existing method declared in this class, or introduces a new method into this class. The method is created with default behavior. If the method overrides a non-private, non-abstract method implemented in a transformed super class, the the default behavior is to invoke that method and return its value. Otherwise, the default behavior is to ignore parameters and return 0, false, or null. Void methods will invoke the super-class implementation (if it exists) and return no value. It is allowed for the method description to indicate an abstract method; however the abstract flag will be removed, and a non-abstract method will be created.- Specified by:
introduceMethodin interfacePlasticClass- Parameters:
description- describes the method name, visibility, return value, etc.- Returns:
- a new (or previously created) PlasticMethod for the method
-
introduceMethod
public PlasticMethod introduceMethod(MethodDescription description, InstructionBuilderCallback callback)
Description copied from interface:PlasticClassReturns an existing method declared in this class, or introduces a new method into this class. The method is created with default behavior. It is allowed for the method description to indicate an abstract method; however the abstract flag will be removed, and a non-abstract method will be created.- Specified by:
introduceMethodin interfacePlasticClass- Parameters:
description- describes the method name, visibility, return value, etc.callback- used to create the implementation of the method- Returns:
- a new (or previously created) PlasticMethod for the method
-
introduceMethod
public PlasticMethod introduceMethod(java.lang.reflect.Method method)
Description copied from interface:PlasticClassA convenience that creates aMethodDescriptionfrom the Method and introduces that. This is often invoked when walking the methods of an interface and introducing each of those methods. Introduced methods are always concrete, not abstract. The abstract flag on the method modifiers will always be stripped off, which is handy when introducing methods from an interface.- Specified by:
