AmbPrefix_c

public AmbPrefix_c(Position pos,
                   Prefix prefix,
                   Id name)

Method Detail

nameNode

public Id nameNode()

Get the name of the prefix.

Specified by:

nameNode in interface AmbPrefix

id

public AmbPrefix id(Id name)

Set the name of the prefix.

name

public java.lang.String name()

Get the name of the prefix.

Specified by:

name in interface AmbPrefix

name

public AmbPrefix name(java.lang.String name)

Set the name of the prefix.

prefix

public Prefix prefix()

Get the prefix of the prefix.

Specified by:

prefix in interface AmbPrefix

prefix

public AmbPrefix prefix(Prefix prefix)

Set the prefix of the prefix.

reconstruct

protected AmbPrefix_c reconstruct(Prefix prefix,
                                  Id name)

Reconstruct the prefix.

visitChildren

public Node visitChildren(NodeVisitor v)

Visit the children of the prefix.

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 prefix.

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 prefix.

Specified by:

exceptionCheck in interface NodeOps

Overrides:

exceptionCheck in class Node_c

Parameters:

ec - The visitor.

Throws:

SemanticException

prettyPrint

public void prettyPrint(CodeWriter w,
                        PrettyPrinter tr)

Write the prefix 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

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
