getRepresentedProperties(/* mPropertyBag */) {
			return Promise.reject("not implemented");
		}
Optional method to provide all properties and the corresponding controls that represent them.
Implement this method if evaluating the binding is not enough e.g. a Table has not yet received a binding or
if e.g. a filter field represents a property without binding.

@param {object} mPropertyBag - Object with parameters as properties
@param {object} mPropertyBag.payload - Payload parameter attached to the delegate, undefined if no payload was assigned
@param {sap.ui.base.ManagedObject} mPropertyBag.element - Control of the element the delegate is attached to
@param {string} mPropertyBag.aggregationName - Name of the aggregation for which delegate should provide
		the property information
@returns {Promise<sap.ui.fl.interfaces.delegate.RepresentedPropertyInfo[]>} Data about properties represented.
				Resolve <code>undefined</code> or don't implement the method if you don't want to take over the check for representation.
				Resolve an empty array if no property is represented at the moment.
