| IsA | () | constructor |
public function IsA(type:Class, clause:* = null)Creates a new IsA operator.
Parameterstype:Class — the class type to check for
|
|
clause:* (default = null) |
| 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.
|
| predicate | () | method |
public override function predicate(o:Object):BooleanBoolean predicate that tests the output of evaluating this expression. Returns true if the expression evaluates to true, or a non-null or non-zero value. Returns false if the expression evaluates to false, or a null or zero value.
Parameterso:Object — the input object to this expression
|
Boolean — the Boolean result of evaluating the 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
