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.

Propriétés publiques

	Propriété		Défini par
		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

Méthodes publiques

	Méthode		Défini par
		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.	IExpressionManager

Détails de la méthode

assignTo

()

méthode

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

Version du langage:

ActionScript 3.0

Version du produit:

Bloc de création Expression Manager 10

Versions du moteur d’exécution:

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.).

Paramètres

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

	`expression:String` — The expression to be evaluated.

manage

public function manage(expression:String):IComputedExpression

Version du langage:

ActionScript 3.0

Version du produit:

Bloc de création Expression Manager 10

Versions du moteur d’exécution:

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.

Paramètres

expression:String — An expression string.

Valeur renvoyée

IComputedExpression — A ComputedExpression instance for the given expression string.

manageExpression

Version du langage:

ActionScript 3.0

Version du produit:

Bloc de création Expression Manager 10

Versions du moteur d’exécution:

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.

Paramètres

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

Valeur renvoyée

IComputedExpression — A ComputedExpression instance for the given expression.

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

Paramètres

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

Valeur renvoyée

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