Method Details

scan

public Void scan(Tree tree,
 Void p)

Overrides:

scan in class BaseTypeVisitor<BaseAnnotatedTypeFactory>

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<BaseAnnotatedTypeFactory>

Parameters:

tree - class to check

processMethodTree

public void processMethodTree(MethodTree tree)

Description copied from class: BaseTypeVisitor

Type-check methodTree. Subclasses should override this method instead of BaseTypeVisitor.visitMethod(MethodTree, Void).

Overrides:

processMethodTree in class BaseTypeVisitor<BaseAnnotatedTypeFactory>

Parameters:

tree - the method to type-check

visitMethodInvocation

public Void visitMethodInvocation(MethodInvocationTree tree,
 Void p)

Description copied from class: BaseTypeVisitor

Performs a method invocation check.

An invocation of a method, m, on the receiver, r is valid only if:

• passed arguments are subtypes of corresponding m parameters
• r is a subtype of m receiver type
• if m is generic, passed type arguments are subtypes of m type variables

Specified by:

visitMethodInvocation in interface TreeVisitor<Void,Void>

Overrides:

visitMethodInvocation in class BaseTypeVisitor<BaseAnnotatedTypeFactory>

visitMemberSelect

public Void visitMemberSelect(MemberSelectTree tree,
 Void p)

Specified by:

visitMemberSelect in interface TreeVisitor<Void,Void>

Overrides:

visitMemberSelect in class TreeScanner<Void,Void>

visitIdentifier

public Void visitIdentifier(IdentifierTree tree,
 Void p)

Specified by:

visitIdentifier in interface TreeVisitor<Void,Void>

Overrides:

visitIdentifier in class BaseTypeVisitor<BaseAnnotatedTypeFactory>

visitAssignment

public Void visitAssignment(AssignmentTree tree,
 Void p)

Description copied from class: BaseTypeVisitor

Performs two checks: subtyping and assignability checks, using BaseTypeVisitor.commonAssignmentCheck(Tree, ExpressionTree, String, Object[]).

If the subtype check fails, it issues an "assignment" error.

Specified by:

visitAssignment in interface TreeVisitor<Void,Void>

Overrides:

visitAssignment in class BaseTypeVisitor<BaseAnnotatedTypeFactory>

visitArrayAccess

public Void visitArrayAccess(ArrayAccessTree tree,
 Void p)

Specified by:

visitArrayAccess in interface TreeVisitor<Void,Void>

Overrides:

visitArrayAccess in class TreeScanner<Void,Void>

visitNewClass

public Void visitNewClass(NewClassTree tree,
 Void p)

Description copied from class: BaseTypeVisitor

Performs a new class invocation check.

An invocation of a constructor, c, is valid only if:

• passed arguments are subtypes of corresponding c parameters
• if c is generic, passed type arguments are subtypes of c type variables

Specified by:

visitNewClass in interface TreeVisitor<Void,Void>

Overrides:

visitNewClass in class BaseTypeVisitor<BaseAnnotatedTypeFactory>

visitNewArray

public Void visitNewArray(NewArrayTree tree,
 Void p)

Specified by:

visitNewArray in interface TreeVisitor<Void,Void>

Overrides:

visitNewArray in class BaseTypeVisitor<BaseAnnotatedTypeFactory>

visitTypeCast

public Void visitTypeCast(TypeCastTree tree,
 Void p)

Specified by:

visitTypeCast in interface TreeVisitor<Void,Void>

Overrides:

visitTypeCast in class BaseTypeVisitor<BaseAnnotatedTypeFactory>

visitInstanceOf

public Void visitInstanceOf(InstanceOfTree tree,
 Void p)

Specified by:

visitInstanceOf in interface TreeVisitor<Void,Void>

Overrides:

visitInstanceOf in class BaseTypeVisitor<BaseAnnotatedTypeFactory>

visitModifiers

public Void visitModifiers(ModifiersTree tree,
 Void p)

Specified by:

visitModifiers in interface TreeVisitor<Void,Void>

Overrides:

visitModifiers in class TreeScanner<Void,Void>

createTypeValidator

protected BaseTypeValidator createTypeValidator()

Overrides:

createTypeValidator in class BaseTypeVisitor<BaseAnnotatedTypeFactory>
