ExpressionManagerImpl  - AS3 Expression Manager
Packagecom.adobe.solutions.exm.runtime.impl
Classpublic class ExpressionManagerImpl
InheritanceExpressionManagerImpl Inheritance Object
Implements IExpressionManager

Language Version: ActionScript 3.0
Product Version: Expression Manager Building Block 10
Runtime Versions: AIR (unsupported), Flash Player 10.2

The default implementation of the ExpressionManager interface, which serves as the entry point into the Expression Manager runtime. An instance of this class must be configured with a variable resolver and function mapper in order to be able to manage expressions with variable references and function calls.


Public Properties
 PropertyDefined By
 Inheritedconstructor : Object

Object
  functionMapper : IFunctionMapper
Returns the function mapper used for resolving function calls in expressions.
ExpressionManagerImpl
  variableResolver : IVariableResolver
Returns the variable resolver used for resolving variables in expressions.

Implementation
    public function get functionMapper():IFunctionMapper
    public function set functionMapper(value:IFunctionMapper):void

variableResolver

property 
variableResolver:IVariableResolver

Language Version: ActionScript 3.0
Product Version: Expression Manager Building Block 10

Method Detail

assignTo

()method
public function assignTo(assignTo:String, expression:String):void

Language Version: ActionScript 3.0
Product Version: Expression Manager Building Block 10
Runtime Versions: AIR (unsupported), Flash Player 10.2

Assigns the result of evaluation of the given expression to the given variable. The target variable is updated automatically whenever an expression recomputation event is triggered (e.g. due to a dependent variable change, etc.).

Parameters

assignTo:String — The target variable to which the result of expression evaluation is assigned.
 
expression:String — The expression to be evaluated.

manage

()method 
public function manage(expression:String):IComputedExpression

Language Version: ActionScript 3.0
Product Version: Expression Manager Building Block 10
Runtime Versions: AIR (unsupported), Flash Player 10.2

Returns a ComputedExpression instance for the given expression string, which applications can use for reading or binding to the result of evaluation of the expression.

Parameters

expression:String — An expression string.

Returns
IComputedExpression — A ComputedExpression instance for the given expression string.

manageExpression

()method 
public function manageExpression(expression:IExpression):IComputedExpression

Language Version: ActionScript 3.0
Product Version: Expression Manager Building Block 10
Runtime Versions: AIR (unsupported), Flash Player 10.2

Returns a ComputedExpression instance for the given expression, and if the 'assignTo' property of the given expression is set, automatically assigns the result of expression evaluation to the variable represented by this property.

Parameters

expression:IExpression — An expression object with the 'expression' property, and optionally the 'assignTo' property, set.

Returns
IComputedExpression — A ComputedExpression instance for the given expression.

manageList

()method 
public function manageList(expressionsVector:Vector.<IExpression>):Vector.<IComputedExpression>

Language Version: ActionScript 3.0
Product Version: Expression Manager Building Block 10
Runtime Versions: AIR (unsupported), Flash Player 10.2

Returns a list of ComputedExpression instances for the given list of expression objects.

Parameters

expressionsVector:Vector.<IExpression> — A list of Expression instances.

Returns
Vector.<IComputedExpression> — A list of ComputedExpression instances for the given list of expressions.
