Detalhes do método

getExpression

()

método

public function getExpression(exprId: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

Fires an asynchronous operation for retrieving the expression with the given ID from the expression repository. Returns immediately and causes the current object to later dispatch one of the following events:

If the operation completes successfully, an event with name "expressionGetEvent" of type ExpressionGetEvent. The 'expression' property of the event will be a reference to the loaded expression object, and will have the same ID as the one passed as input to this method.
If the operation errors out, an event with name "expressionGetError" of type ErrorEvent. The 'error' property of the event will contain the actual error thrown by the operation.

Parâmetros

exprId:String — The ID of the expression to be retrieved.

listExpressions

()

método

public function listExpressions():String

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Expression Manager Building Block 10

Versões de runtime:

AIR (unsupported), Flash Player 10.2

Fires an asynchronous operation for retrieving the list of all available expressions. Returns immediately and causes the current object to later dispatch one of the following events:

If the operation completes successfuly, an event with name "expressionListProviderEvent" of type ExpressionListProviderEvent. The 'expressions' property of the event will be a reference to the list of expressions (IExpression objects) in the system. The 'requestId' property of the event will be the same as the value returned by this method, which is a unique string that calling code can use for correlating calls to this method with events dispatched later.
If the operation errors out, an event with name "expressionListError" of type RequestAwareErrorEvent. The 'requestId' property of the event will be the same as the value returned by this method, while the 'error' property will contain the actual error thrown by the operation.

Retorna

String — A unique request ID which calling code can use for correlating invocations of this method with events dispatched later.

newExpression

()

método

public function newExpression():IExpression

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Expression Manager Building Block 10

Versões de runtime:

AIR (unsupported), Flash Player 10.2

Creates a new transient expression object and returns it.

Retorna

IExpression — A new transient expression object.

searchExpressions

()

método

public function searchExpressions(searchTerm:String):String

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Expression Manager Building Block 10

Versões de runtime:

AIR (unsupported), Flash Player 10.2

Fires an asynchronous operation for retrieving the list of available expressions matching the given search term. Returns immediately and causes the current object to later dispatch one of the following events:

If the operation completes successfuly, an event with name "expressionListProviderEvent" of type ExpressionListProviderEvent. The 'expressions' property of the event will be a reference to the list of matching expressions (IExpression objects). The 'requestId' property of the event will be the same as the value returned by this method, which is a unique string that calling code can use for correlating calls to this method with events dispatched later.
If the operation errors out, an event with name "expressionListError" of type RequestAwareErrorEvent. The 'requestId' property of the event will be the same as the value returned by this method, while the 'error' property will contain the actual error thrown by the operation.

Parâmetros

searchTerm:String

Retorna

String — A unique request ID which calling code can use for correlating invocations of this method with events dispatched later.

validate

()

método

public function validate(expressions:IList):void

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Expression Manager Building Block 10

Versões de runtime:

AIR (unsupported), Flash Player 10.2

Validates a batch of expressions (IExpression instances) for syntactic correctness and cyclic dependencies. Returns quietly if validation succeeds, else throws one of the following errors:

ExpressionValidationError if any of the expressions is syntactically incorrect.
SimpleCyclicDependencyError if a simple cycle involving one variable is detected in an expression.
ComplexCyclicDependencyError if a complex cycle involving two or more variables is detected over multiple expressions.

Parâmetros

expressions:IList — The list of expressions (IExpression instances) to be validated.
