public class FieldAssign_c
extends Assign_c
implements FieldAssign

A FieldAssign_c represents a Java assignment expression to a field. For instance, this.x = e. The class of the Expr returned by FieldAssign_c.left()is guaranteed to be a Field.

Constructor Detail

FieldAssign_c

public FieldAssign_c(Position pos,
                     Field left,
                     Assign.Operator op,
                     Expr right)

Method Detail

left

public Assign left(Expr left)

Description copied from class: Assign_c

Set the left operand of the expression.

Specified by:

left in interface Assign

Overrides:

left in class Assign_c

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

Specified by:

firstChild in class Assign_c

acceptCFGAssign

protected void acceptCFGAssign(CFGBuilder v)

Description copied from class: Assign_c

###@@@DOCO TODO

Specified by:

acceptCFGAssign in class Assign_c

acceptCFGOpAssign

protected void acceptCFGOpAssign(CFGBuilder v)

Description copied from class: Assign_c

###@@@DOCO TODO

Specified by:

acceptCFGOpAssign in class Assign_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 Assign_c
