Method Detail

processClassTree

public void processClassTree(com.sun.source.tree.ClassTree node)

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:

node - class to check

visitMethod

public java.lang.Void visitMethod(com.sun.source.tree.MethodTree node,
                                  java.lang.Void p)

Description copied from class: BaseTypeVisitor

Performs pseudo-assignment check: checks that the method obeys override and subtype rules to all overridden methods.

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 com.sun.source.tree.TreeVisitor<java.lang.Void,java.lang.Void>

Overrides:

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

visitVariable

public java.lang.Void visitVariable(com.sun.source.tree.VariableTree node,
                                    java.lang.Void p)

Specified by:

visitVariable in interface com.sun.source.tree.TreeVisitor<java.lang.Void,java.lang.Void>

Overrides:

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