             Stmt body)

Method Detail

decl

public LocalDecl decl()

Specified by:

decl in interface ExtendedFor

decl

public ExtendedFor decl(LocalDecl decl)

Specified by:

decl in interface ExtendedFor

decl

protected <N extends ExtendedFor_c> N decl(N n,
                               LocalDecl decl)

expr

public Expr expr()

Specified by:

expr in interface ExtendedFor

expr

public ExtendedFor expr(Expr expr)

Specified by:

expr in interface ExtendedFor

expr

protected <N extends ExtendedFor_c> N expr(N n,
                               Expr expr)

reconstruct

protected <N extends ExtendedFor_c> N reconstruct(N n,
                                      LocalDecl decl,
                                      Expr expr)

Reconstruct the statement.

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.

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

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

acceptCFG

public <T> java.util.List<T> acceptCFG(CFGBuilder<?> v,
                              java.util.List<T> succs)

Description copied from interface: TermOps

Visit this term in evaluation order, calling v.edge() for each successor in succs, if data flows on that edge.

Specified by:

acceptCFG in interface TermOps

Specified by:

acceptCFG in class Term_c

continueTarget

public Term continueTarget()

Description copied from interface: LoopOps

Target of a continue statement in the loop body.

Specified by:

continueTarget in interface LoopOps

prettyPrint

public void prettyPrint(CodeWriter w,
               PrettyPrinter tr)

Description copied from class: Node_c

Pretty-print the AST using the given CodeWriter.

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.
