public function If(test:*, thenExpr:*, elseExpr:*)Create a new IfExpression.
Parameterstest:* — the test expression for the if statement
|
|
thenExpr:* — the expression to evaluate if the test predicate
evaluates to true
|
|
elseExpr:* — the expression to evaluate if the test predicate
evaluates to false
|
| clone | () | method |
public override function clone():ExpressionCreates a cloned copy of the expression. Recursively clones any sub-expressions.
ReturnsExpression —
the cloned expression.
|
| eval | () | method |
public override function eval(o:Object = null):*Evaluates this expression with the given input object.
Parameterso:Object (default = null) |
* — the result of evaluating the expression
|
| getChildAt | () | method |
public override function getChildAt(idx:int):ExpressionReturns the sub-expression at the given index.
Parametersidx:int — the index of the child sub-expression
|
Expression —
the requested sub-expression.
|
| setChildAt | () | method |
public override function setChildAt(idx:int, expr:Expression):BooleanSet the sub-expression at the given index.
Parametersidx:int — the index of the child sub-expression
|
|
expr:Expression — the sub-expression to set
|
Boolean — true if the the sub-expression was successfully set,
false otherwise
|
| toString | () | method |
public override function toString():StringReturns a string representation of the expression.
ReturnsString — this expression as a string value
