| Literal | () | constructor |
public function Literal(val:Object = null)Creates a new Literal instance.
Parametersval:Object (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
|
| 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
