Class AccessorMethods

  abc.aspectj.visit.AccessorMethods

public class AccessorMethods
extends java.lang.Object

Container class for storing accessor methods related to an aspect. AccessorDecl has an instance of this as a member. We have several kinds of accessor methods - field getter and setter methods, method dispatch accessors, and methods to access the this pointer of textually enclosing classes. You can create an accessor method (or obtain an existing one, if it was created earlier) by calling one of the accessor*() methods with the appropriate arguments. Most things are taken care of automatically - methods are registered with MethodCategory using the right values etc. The only thing that needs to be done is to invoke addAllSootMethods() from the inter-type adjuster in order to insert the method bodies into the corresponding classes.

Method Detail

tag

protected java.lang.String tag()

Subclasses should override this to alter how names are generated. For example, for a "Get" accessor method, the name will be a unique ID based on "get$" + tag() + "$" + {fieldname}. ...although this behaviour is somewhat deprecated, as all accessors are created in this class. Perhaps we should have a "tag" argument to the accessor* calls, so that we can have get$super$f() and get$privileged$f() - it's certainly not important, though.

findExistingAccessor
