Method Detail

callObject

protected abstract java.lang.Object callObject(BuildContext context,
                                               java.lang.Object onObject,
                                               java.lang.Object identifier)
                                        throws TemplateRuntimeException

Distinguishes between maps, lists and other objects. If object is a map, it resolves the return value from the map. If the object is a list and the identifier is a number, it resolves the return value from the list. If the object is an array and the identifier is a number, it resolves the return value from the array. In any other case, it invokes the method with the specified identifier and the parameters on the object. It depends on the call in which order the options are used.

Parameters:

onObject - the object

identifier - the name of the map entry, the index of the list, or the name of the method.

parameters - the parameters

Returns:

the result
