ExpressionManagerImpl - Referência da API Adobe ActionScript® 3 (AS3 Expression Manager)

Pacote	com.adobe.solutions.exm.runtime.impl
Classe	public class ExpressionManagerImpl
Herança	ExpressionManagerImpl Object
Implementações	IExpressionManager

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Expression Manager Building Block 10

Versões de 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.

Detalhes do método

assignTo

()

método

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

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Expression Manager Building Block 10

Versões de 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.).

Parâmetros

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

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

manage

()

método

public function manage(expression:String):IComputedExpression

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Expression Manager Building Block 10

Versões de 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.

Parâmetros

expression:String — An expression string.

Retorna

IComputedExpression — A ComputedExpression instance for the given expression string.

manageExpression

()

método

public function manageExpression(expression:IExpression):IComputedExpression

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Expression Manager Building Block 10

Versões de 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.

Parâmetros

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

Retorna

IComputedExpression — A ComputedExpression instance for the given expression.

manageList

()

método

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

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Expression Manager Building Block 10

Versões de runtime:

AIR (unsupported), Flash Player 10.2

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

Parâmetros

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

Retorna

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