ExpressionManagerImpl - Guida di riferimento alle API Adobe ActionScript® 3 (AS3 Expression Manager)

Pacchetto	com.adobe.solutions.exm.runtime.impl
Classe	public class ExpressionManagerImpl
Ereditarietà	ExpressionManagerImpl Object
Implementa	IExpressionManager

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Blocco costitutivo Expression Manager 10

Versioni runtime:

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.

Descrizione dei metodi

assignTo

()

metodo

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

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Blocco costitutivo Expression Manager 10

Versioni runtime:

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.).

Parametri

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

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

manage

()

metodo

public function manage(expression:String):IComputedExpression

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Blocco costitutivo Expression Manager 10

Versioni runtime:

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.

Parametri

expression:String — An expression string.

Restituisce

IComputedExpression — A ComputedExpression instance for the given expression string.

manageExpression

()

metodo

public function manageExpression(expression:IExpression):IComputedExpression

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Blocco costitutivo Expression Manager 10

Versioni runtime:

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.

Parametri

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

Restituisce

IComputedExpression — A ComputedExpression instance for the given expression.

manageList

()

metodo

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

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Blocco costitutivo Expression Manager 10

Versioni runtime:

AIR (unsupported), Flash Player 10.2

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

Parametri

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

Restituisce

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