public java.lang.String name()
- Description copied from interface:

- Ambiguous name.
- Specified by:

in interface AmbTypeNode
name
public AmbTypeNode name(java.lang.String name)
- Description copied from interface:
AmbTypeNode
- Set the ambiguous name.
- Specified by:

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.

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
- Specified by:
typeCheck
in interface NodeOps
- Overrides:
typeCheck
in class Node_c
- 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)

CodeWriter
.
- Specified by:
prettyPrint
in interface NodeOps
- Specified by:

translate
public void translate(CodeWriter w,
Translator tr)
- Description copied from class:
Node_c
- Translate the AST using the given
CodeWriter
.
- Specified by:
translate
in interface NodeOps
- Overrides:
translate
in class Node_c
- Parameters:
w
- The code writer to which to write.tr
- The translation pass. This is not a visitor.
