Method Detail

qualifier

public Qualifier qualifier()

Description copied from interface: QualifierNode

The qualifier type object.

Specified by:

qualifier in interface QualifierNode

name

public java.lang.String name()

Description copied from interface: AmbQualifierNode

Ambiguous name.

Specified by:

name in interface AmbQualifierNode

name

public AmbQualifierNode name(java.lang.String name)

qual

public QualifierNode qual()

Description copied from interface: AmbQualifierNode

Qualifier of the qualifier.

Specified by:

qual in interface AmbQualifierNode

qual

public AmbQualifierNode qual(QualifierNode qual)

qualifier

public AmbQualifierNode qualifier(Qualifier qualifier)

reconstruct

protected AmbQualifierNode_c reconstruct(QualifierNode qual)

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.

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 Node_c

Parameters:

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

Throws:

SemanticException

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.

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 Node_c

Parameters:

ec - The visitor.

Throws:

SemanticException
