Method Details

[hide private]

when(subject)
Static Method

source code

Condition under which this adapter is applicable to the given subject. The condition can either be a staticmethod callable that results in a boolean value or a string that will be evaluated as a boolean Python expression in the namespace in which it is defined. This implies any variables in the global namespace of the Adapter subclass can be used in the when clause. String conditions are only evaluated once at startup rather than on each call. If the condition is None, the Adapter is considered a default.

Parameters:

subject (POR) - POR to test

Returns: boolean

True when the subject meets the condition named in the docstring for this class, False otherwise

Overrides: when

create(self)

source code

Returns a complete POR built based on the subject POR. The complete POR is guaranteed to match the definition of an LSR point of regard with a proper accessible and item index.

This method resolves any problems introduced by the DefaultEventHandlerAdapter when it creates PORs for state, property, and children events. These events can originate from children that are items according to LSR, not full accessibles. When this method is called, it checks if the accessible in the POR is an immediate descendant of an accessible that has STATE_MANAGES_DESCENDANT. If so, it create a POR with that parent as the accessible and the item of the descendant as the item index. Otherwise, the original POR is returned.

Returns: POR

Point of regard
