Class Variable Details [hide private]

when

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 AEAccAdapter 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 AEAccAdapter is considered a default.
Type:
string or callable
Value:
None

singleton

If True, only one instance of this adapter will be registered for use such that it is reused for all subjects.

If False, this class will be registered for use such that it will act as a factory for producing adapter instances for all subjects.
Type:
boolean
Value:
False
