Method Detail

precedence

public Precedence precedence()

Get the precedence of the field.

Specified by:

precedence in interface Expr

Overrides:

precedence in class Expr_c

id

public Id id()

Get the name of the expression.

Specified by:

id in interface AmbExpr

id

public AmbExpr id(Id id)

Set the name of the expression.

Specified by:

id in interface AmbExpr

name

public java.lang.String name()

Get the name of the expression.

Specified by:

name in interface AmbExpr

name

public AmbExpr name(java.lang.String name)

Set the name of the expression.

Specified by:

name in interface AmbExpr

reconstruct

protected AmbExpr_c reconstruct(Id name)

Reconstruct the expression.

visitChildren

public Node visitChildren(NodeVisitor v)

Visit the children of the constructor.

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 ar)
                  throws SemanticException

Disambiguate the expression.

Specified by:

disambiguate in interface NodeOps

Overrides:

disambiguate in class Node_c

Parameters:

ar - 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

Check exceptions thrown by the expression.

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)

Write the expression to an output file.

Specified by:

prettyPrint in interface NodeOps

Overrides:

prettyPrint in class Node_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 Node_c

firstChild

public Term firstChild()

Return the first (sub)term performed when evaluating this term.

Specified by:

firstChild in interface Term

acceptCFG

public java.util.List acceptCFG(CFGBuilder v,
                                java.util.List succs)

Visit this term in evaluation order.

Specified by:

acceptCFG in interface Term

Specified by:

acceptCFG in class Term_c

copy

public Node copy(NodeFactory nf)

Description copied from interface: NodeOps

Produce a copy of this node using the given NodeFactory.

Specified by:

copy in interface NodeOps

Overrides:

copy in class Node_c
