extends ControlBinding

A ControlBinding that binds an datacontrol action, including navigational actions such as "Next" and "Prev", or other actions such as "Commit" and "Rollback", to a view component.

java.util.List	getErrors() Returns a list of errors that were raised during the last invoke operation call.
OperationInfo	getOperationInfo() Returns a description of the operation to invoke.
java.util.Map	getParamsMap() Retuns a map of name-value pairs of arguments and argument values to be passed to the bound operation.
java.lang.Object	getResult() Returns the result of invoking the operation bound by this binding (if the method has been already invoked.
boolean	isOperationEnabled() Whether the action binding is enabled or disabled.

Method Detail

isOperationEnabled

public boolean isOperationEnabled()

Whether the action binding is enabled or disabled.

Returns:

True if the action is currently enabled. False otherwise.

execute

public java.lang.Object execute()

Executes this OperationBinding, for example, as a result of a UI button being pressed. This should translate into invoking some operation on the underlying data control. If there are exceptions within the invoke operation, these exceptions should be accessible via getErrors().

Returns:

the result of the operation (null if the operation has no return type (void).

getErrors

public java.util.List getErrors()

Returns a list of errors that were raised during the last invoke operation call.

Returns:

A list of Throwable that were raised during setInputValue(). It returns null if there is no error occurred.

getOperationInfo

public OperationInfo getOperationInfo()

Returns a description of the operation to invoke. If this operation is a built in operation, this method may return null or no MethodInfo.

getParamsMap

public java.util.Map getParamsMap()

Retuns a map of name-value pairs of arguments and argument values to be passed to the bound operation.

getResult

public java.lang.Object getResult()

Returns the result of invoking the operation bound by this binding (if the method has been already invoked. This method may not force the method invocation.) This method may return null in case the method has not been invoked.
