Method Detail

members

public java.util.List<ClassMember> members()

Description copied from interface: ClassBody

List of the class's members.

Specified by:

members in interface ClassBody

Returns:

A list of ClassMember.

members

public ClassBody members(java.util.List<ClassMember> members)

Description copied from interface: ClassBody

Set the class's members.

Specified by:

members in interface ClassBody

Parameters:

members - A list of ClassMember.

members

protected <N extends ClassBody_c> N members(N n,
                                java.util.List<ClassMember> members)

addMember

public ClassBody addMember(ClassMember member)

Description copied from interface: ClassBody

Add a member to the class, returning a new node.

Specified by:

addMember in interface ClassBody

reconstruct

protected <N extends ClassBody_c> N reconstruct(N n,
                                    java.util.List<ClassMember> members)

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.

buildTypesEnter

public NodeVisitor buildTypesEnter(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 enter() method of the visitor. The * method should perform work that should be done before visiting the children of the node. The method may return this or a new copy of the node on which visitChildren() and leave() will be invoked.

Specified by:

buildTypesEnter in interface NodeOps

Overrides:

buildTypesEnter in class Node_c

Parameters:

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

Throws:

SemanticException

disambiguate

public Node disambiguate(AmbiguityRemover ar)
                  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:

ar - The visitor which disambiguates.

Throws:

SemanticException

toString

public java.lang.String toString()

Overrides:

toString in class Node_c

duplicateFieldCheck

protected void duplicateFieldCheck(TypeChecker tc)
                            throws SemanticException

Throws:

SemanticException

duplicateConstructorCheck

protected void duplicateConstructorCheck(TypeChecker tc)
                                  throws SemanticException

Throws:

SemanticException

duplicateMethodCheck

protected void duplicateMethodCheck(TypeChecker tc)
                             throws SemanticException

Throws:

SemanticException

duplicateMemberClassCheck

protected void duplicateMemberClassCheck(TypeChecker tc)
                                  throws SemanticException

Throws:

protected boolean isSameMethod(TypeSystem ts,
                   MethodInstance mi,
                   MethodInstance mj)

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

exceptionCheckEnter

public NodeVisitor exceptionCheckEnter(ExceptionChecker ec)
                                throws SemanticException

Description copied from interface: NodeOps

Check that exceptions are properly propagated throughout the AST. This method is called by the enter() method of the visitor. The * method should perform work that should be done before visiting the children of the node. The method may return this or a new copy of the node on which visitChildren() and leave() will be invoked.

Specified by:

exceptionCheckEnter in interface NodeOps

Overrides:

exceptionCheckEnter in class Node_c

Parameters:

ec - The visitor.

SemanticException

prettyPrint

public void prettyPrint(CodeWriter w,

Parameters:

w - The code writer to which to write.

tr - The pretty printer. This is not a visitor.

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

copy

public Node copy(NodeFactory nf)

Description copied from interface: NodeOps

Produce a copy of this node using the given NodeFactory.
