Constructor Detail

Assert_c

public Assert_c(Position pos,
                Expr cond,
                Expr errorMessage)
Method Detail

cond

public Expr cond()
Get the condition to check.

Specified by:
cond in interface Assert

cond

public Assert cond(Expr cond)
Set the condition to check.

Specified by:
cond in interface Assert

errorMessage

public Expr errorMessage()
Get the error message to report.

Specified by:
errorMessage in interface Assert

errorMessage

public Assert errorMessage(Expr errorMessage)
Set the error message to report.

Specified by:
errorMessage in interface Assert

reconstruct

protected Assert_c reconstruct(Expr cond,
                               Expr errorMessage)
Reconstruct the statement.


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

childExpectedType

public Type childExpectedType(Expr child,
                              AscriptionVisitor av)
Description copied from interface: Node
Get the expected type of a child expression of this. The expected type is determined by the context in that the child occurs (e.g., for x = e, the expected type of e is the declared type of x. The expected type should impose the least constraints on the child's type that are allowed by the parent node.

Specified by:
childExpectedType in interface Node
Overrides:
childExpectedType in class Node_c
Parameters:
child - A child expression of this node.
av - An ascription visitor.
Returns:
The expected type of child.

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.

translate

public void translate(CodeWriter w,
                      Translator tr)
Description copied from class: Node_c
Translate the AST using the given CodeWriter.

Specified by:
translate in interface NodeOps
Overrides:
translate in class Node_c
Parameters:
w - The code writer to which to write.
tr - The translation pass. This is not a visitor.

entry

public Term entry()
Description copied from class: Term_c
Return the first (sub)term performed when evaluating this term.

Specified by:
entry in interface Term
Specified by:
entry in class Term_c

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
