Method Details

processClassTree

public void processClassTree(ClassTree tree)

Description copied from class: BaseTypeVisitor

Type-check classTree. Subclasses should override this method instead of BaseTypeVisitor.visitClass(ClassTree, Void).

Overrides:

processClassTree in class BaseTypeVisitor<GenericAnnotatedTypeFactory<?,?,?,?>>

Parameters:

tree - class to check

visitMethod

public Void visitMethod(MethodTree tree,
 Void p)

Description copied from class: BaseTypeVisitor

Checks that the method or constructor obeys override and subtype rules to all overridden methods. (Uses the pseudo-assignment logic to do so.)

The override rule specifies that a method, m1, may override a method m2 only if:

• m1 return type is a subtype of m2
• m1 receiver type is a supertype of m2
• m1 parameters are supertypes of corresponding m2 parameters

Also, it issues a "missing.this" error for static method annotated receivers.

Specified by:

visitMethod in interface TreeVisitor<Void,Void>

Overrides:

visitMethod in class BaseTypeVisitor<GenericAnnotatedTypeFactory<?,?,?,?>>

visitVariable

public Void visitVariable(VariableTree tree,
 Void p)

Specified by:

visitVariable in interface TreeVisitor<Void,Void>

Overrides:

visitVariable in class BaseTypeVisitor<GenericAnnotatedTypeFactory<?,?,?,?>>
