Method Detail

isDisambiguated

public boolean isDisambiguated()

Specified by:

isDisambiguated in interface Node

Overrides:

isDisambiguated in class Node_c

Returns:

true if the all type information for the node (but not necessarily for the node's children) is unambiguous.

memberInstance

public MemberInstance memberInstance()

Specified by:

memberInstance in interface ClassMember

procedureInstance

public ProcedureInstance procedureInstance()

Description copied from interface: ProcedureDecl

The procedure's type object. This field may not be valid until after signature disambiguation.

Specified by:

procedureInstance in interface ProcedureDecl

Specified by:

procedureInstance in class ProcedureDecl_c

constructorInstance

public ConstructorInstance constructorInstance()

Description copied from interface: ConstructorDecl

The constructor's type object. This field may not be valid until after signature disambiguation.

Specified by:

constructorInstance in interface ConstructorDecl

constructorInstance

public ConstructorDecl constructorInstance(ConstructorInstance ci)

Description copied from interface: ConstructorDecl

Set the constructor's type object.

Specified by:

constructorInstance in interface ConstructorDecl

constructorInstance

protected <N extends ConstructorDecl_c> N constructorInstance(N n,
                                                  ConstructorInstance ci)

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

enterScope

public Context enterScope(Context c)

Description copied from class: Node_c

Push a new scope upon entering this node, and add any declarations to the context that should be in scope when visiting children of this node.

Specified by:

enterScope in interface NodeOps

Overrides:

enterScope in class Node_c

Parameters:

c - the current Context

Returns:

the Context to be used for visiting this node.

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

extRewrite

public Node extRewrite(ExtensionRewriter rw)
                throws SemanticException

Description copied from interface: NodeOps

Rewrite the AST for the compilation in this language. 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:

extRewrite in interface NodeOps

Overrides:

extRewrite in class Term_c

Parameters:

rw - The visitor.

Throws:

SemanticException

toString

public java.lang.String toString()

Overrides:

toString in class Node_c

Description copied from interface: ProcedureDeclOps

Pretty-print the procedure's header using the given code writer.

Specified by:

prettyPrintHeader in interface ProcedureDeclOps

firstChild

public Term firstChild()

Description copied from interface: TermOps

Return the first direct subterm performed when evaluating this term. If this term has no subterms, this should return null. This method is similar to the deprecated entry(), but it should *not* recursively drill down to the innermost subterm. The direct child visited first in this term's dataflow should be returned.

Specified by:

firstChild in interface TermOps

Specified by:

firstChild in class Term_c

Specified by:

acceptCFG in interface TermOps

Specified by:

copy

public Node copy(NodeFactory nf)

Description copied from interface: NodeOps

Produce a copy of this node using the given NodeFactory.
