public AmbTypeNode_c(Position pos,
                     QualifierNode qual,
                     Id name)

Method Detail

id

public Id id()

Description copied from interface: AmbTypeNode

Ambiguous name.

Specified by:

id in interface AmbTypeNode

id

public AmbTypeNode id(Id name)

Description copied from interface: AmbTypeNode

Set the ambiguous name.

Specified by:

id in interface AmbTypeNode

name

public java.lang.String name()

Description copied from interface: TypeNode

Short name of the type, or null if not a Named type.

Specified by:

name in interface AmbTypeNode

Specified by:

name in interface TypeNode

Overrides:

name in class TypeNode_c

name

public AmbTypeNode name(java.lang.String name)

Description copied from interface: AmbTypeNode

Set the ambiguous name.

Specified by:

name in interface AmbTypeNode

qual

public QualifierNode qual()

Description copied from interface: AmbTypeNode

Qualifier of the type.

Specified by:

qual in interface AmbTypeNode

qual

public AmbTypeNode qual(QualifierNode qual)

Description copied from interface: AmbTypeNode

Set the qualifier of the type.

Specified by:

qual in interface AmbTypeNode

reconstruct

protected AmbTypeNode_c reconstruct(QualifierNode qual,
                                    Id name)

buildTypes

public Node buildTypes(TypeBuilder tb)
                throws SemanticException

Description copied from interface: NodeOps

Collects classes, methods, and fields from the AST rooted at this node and constructs type objects for these. These type objects may be ambiguous. Inserts classes into the TypeSystem. This method is called by the leave() method of the visitor. The method should perform work that should be done after visiting the children of the node. The method may return this or a new copy of the node which will be installed as a child of the node's parent.

Specified by:

buildTypes in interface NodeOps

Overrides:

buildTypes in class TypeNode_c

Parameters:

tb - The visitor which adds new type objects to the TypeSystem.

Throws:

SemanticException

visitChildren

public Node visitChildren(NodeVisitor v)

Description copied from interface: NodeOps

Visit the children of the node.

Specified by:

visitChildren in interface NodeOps

Overrides:

visitChildren in class Node_c

Parameters:

v - The visitor that will traverse/rewrite the AST.

Returns:

A new AST if a change was made, or this.

disambiguate

public Node disambiguate(AmbiguityRemover sc)
                  throws SemanticException

Description copied from interface: NodeOps

Remove any remaining ambiguities from the AST. This method is called by the leave() method of the visitor. The method should perform work that should be done after visiting the children of the node. The method may return this or a new copy of the node which will be installed as a child of the node's parent. The node should not assume that its children have been disambiguated. If it depends on a child being disambiguated, it may just return this without doing any work.

Specified by:

disambiguate in interface NodeOps

Overrides:

disambiguate in class Node_c

Parameters:

sc - The visitor which disambiguates.

Throws:

SemanticException

typeCheck

public Node typeCheck(TypeChecker tc)
               throws SemanticException

Description copied from interface: NodeOps

Type check the AST. This method is called by the leave() method of the visitor. The method should perform work that should be done after visiting the children of the node. The method may return this or a new copy of the node which will be installed as a child of the node's parent.

Specified by:

typeCheck in interface NodeOps

Overrides:

typeCheck in class Node_c

Parameters:

tc - The type checking visitor.

Throws:

SemanticException

exceptionCheck

public Node exceptionCheck(ExceptionChecker ec)
                    throws SemanticException

Description copied from interface: NodeOps

Check that exceptions are properly propagated throughout the AST. This method is called by the leave() method of the visitor. The method should perform work that should be done after visiting the children of the node. The method may return this or a new copy of the node which will be installed as a child of the node's parent.

Specified by:

exceptionCheck in interface NodeOps

Overrides:

exceptionCheck in class Term_c

Parameters:

ec - The visitor.

Throws:

SemanticException

prettyPrint

public void prettyPrint(CodeWriter w,
                        PrettyPrinter tr)

Description copied from class: Node_c

Pretty-print the AST using the given CodeWriter.

Specified by:

prettyPrint in interface NodeOps

Specified by:

prettyPrint in class TypeNode_c

Parameters:

w - The code writer to which to write.

tr - The pretty printer. This is not a visitor.

toString

public java.lang.String toString()

Overrides:

toString in class TypeNode_c
