Constructor Detail

Labeled_c

public Labeled_c(Position pos,
                 Id label,
                 Stmt statement)
Method Detail

labelNode

public Id labelNode()
Get the label of the statement.

Specified by:
labelNode in interface Labeled

labelNode

public Labeled labelNode(Id label)
Set the label of the statement.

Specified by:
labelNode in interface Labeled

label

public java.lang.String label()
Get the label of the statement.

Specified by:
label in interface Labeled

label

public Labeled label(java.lang.String label)
Set the label of the statement.

Specified by:
label in interface Labeled

statement

public Stmt statement()
Get the sub-statement of the statement.

Specified by:
statement in interface Labeled

statement

public Labeled statement(Stmt statement)
Set the sub-statement of the statement.

Specified by:
statement in interface Labeled

reconstruct

protected Labeled_c reconstruct(Id label,
                                Stmt statement)
Reconstruct the statement.


visitChildren

public Node visitChildren(NodeVisitor v)
Visit the children of the statement.

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.

toString

public java.lang.String toString()
Overrides:
toString in class Node_c

prettyPrint

public void prettyPrint(CodeWriter w,
                        PrettyPrinter tr)
Write the statement 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.

firstChild

public Term firstChild()
Description copied from interface: Term
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 Term

acceptCFG

public java.util.List acceptCFG(CFGBuilder v,
                                java.util.List succs)
Description copied from class: Term_c
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
