Class BooleanOperator

The BooleanOperator class is used to combine multiple filters for the filter method in the Model class, to specify whether the next filter will be negated or else the two following filters are combined with And/Or.

This class is not required to be instanced as its members can be directly used by specifying the class members.

To see some usage examples you can look at the page Usage examples.

Members

NOT

NOT = '!'

The next filter will be negated, and it will return True if the filter result would be False or the opposite.

AND

AND = '&'

The next two filters will be combined with a boolean And. This is the default also if the operator is not specified and two filters are combined.

OR

OR = '|'

The next two filters will be combined with a boolean Or.
