Whether the action binding is enabled or disabled.

Returns:

True if the action is currently enabled. False otherwise.

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

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.
