Constructor Detail

ArrayAccess_c

public ArrayAccess_c(Position pos,
                     Expr array,
                     Expr index)
Method Detail

precedence

public Precedence precedence()
Get the precedence of the expression.

Specified by:
precedence in interface Expr
Overrides:
precedence in class Expr_c

array

public Expr array()
Get the array of the expression.

Specified by:
array in interface ArrayAccess

array

public ArrayAccess array(Expr array)
Set the array of the expression.

Specified by:
array in interface ArrayAccess

index

public Expr index()
Get the index of the expression.

Specified by:
index in interface ArrayAccess

index

public ArrayAccess index(Expr index)
Set the index of the expression.

Specified by:
index in interface ArrayAccess

flags

public Flags flags()
Return the access flags of the variable.

Specified by:
flags in interface Variable

reconstruct

protected ArrayAccess_c reconstruct(Expr array,
                                    Expr index)
Reconstruct the expression.


visitChildren

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

Specified by:
visitChildren in interface NodeOps
Overrides:
visitChildren in class Node_c

typeCheck

public Node typeCheck(TypeChecker tc)
               throws SemanticException
Type check the expression.

Specified by:
typeCheck in interface NodeOps
Overrides:
typeCheck in class Node_c
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

toString

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

prettyPrint

public void prettyPrint(CodeWriter w,
                        PrettyPrinter tr)
Write the expression to an output file.

Specified by:
prettyPrint in interface NodeOps
Overrides:
prettyPrint in class Node_c

entry

public Term entry()
Description copied from interface: Term
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 interface: Term
Visit this node, calling calling v.edge() for each successor in succs, if data flows on that edge.

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

throwTypes

public java.util.List throwTypes(TypeSystem ts)
Description copied from interface: NodeOps
List of Types of exceptions that might get thrown. The result is not necessarily correct until after type checking.

Specified by:
throwTypes in interface NodeOps
Overrides:
throwTypes in class Node_c
