IExpressionManager  - AS3 Expression Manager
Packagecom.adobe.solutions.exm.runtime
Interfacepublic interface IExpressionManager
Implementors ExpressionManagerImpl

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

The ExpressionManager interface is the entry point into the Expression Manager runtime. Applications should use an ExpressionManager instance for obtaining a ComputedExpression instance, from which they can obtain the result of the evaluated expression by reading or binding to the 'value' property. ExpressionManager has two pluggable components, a variable resolver and a function mapper, which are used for resolving any variables or function calls encountered in an expression string.


Public Properties
 PropertyDefined By
  functionMapper : IFunctionMapper
Returns the function mapper used for resolving function calls in expressions.
IExpressionManager
  variableResolver : IVariableResolver
Returns the variable resolver used for resolving variables in expressions.
IExpressionManager
Public Methods
 MethodDefined By
  
assignTo(assignTo:String, expression:String):void
Assigns the result of evaluation of the given expression to the given variable.
IExpressionManager
  
manage(expression:String):IComputedExpression
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.
IExpressionManager
  
manageExpression(expression:IExpression):IComputedExpression
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.
IExpressionManager
  
manageList(expressionsVector:Vector.<IExpression>):Vector.<IComputedExpression>
Returns a list of ComputedExpression instances for the given list of expression objects.

Returns the function mapper used for resolving function calls 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.
