traits.constants.ComparisonMode = <enum 'ComparisonMode'>[source]

Comparison mode.

Indicates when trait change notifications should be generated based upon the result of comparing the old and new values of a trait assignment:

Enumeration members:

none

The values are not compared and a trait change notification is generated on each assignment.

identity

A trait change notification is generated if the old and new values are not the same object.

equality

A trait change notification is generated if the old and new values are not the same object, and not equal using Python’s standard equality testing. This is the default.
