public interface OperationBinding
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.

Method Detail

isOperationEnabled

boolean isOperationEnabled()

Whether the action binding is enabled or disabled.

Returns:

True if the action is currently enabled. False otherwise.

execute

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).

getOperationInfo

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

java.util.Map getParamsMap()

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

getResult

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.
