If this feature has no ParentFeature, then its effective polarity is the value of the Polarity property. If this feature has a ParentFeature, then the effective polarity is the Polarity times the effective polarity of the ParentFeature.

If this feature has no ParentFeature, then its effective weight is the value of the Weight property. If this feature has a ParentFeature, then the effective weight is the Weight times the effective weight of the ParentFeature.

Re-enables raising of the Changed event after SuspendChangedEvent has been called, and raises the Changed event if the ChangedEventSuspended count is reduced to zero and any changes were made while events were suspended. Must be called once for each call to SuspendChangedEvent.

Temporarily suspends the raising of the Changed event. May be called more than once, and a corresponding call to ResumeAndRaiseChangedEvent must be made for each call to SuspendChangedEvent.

Indicates if the raising of the Changed event has been suspended.

If this feature has a ParentFeature, then Weight and Polarity are defined with respect to the parent. The effective weight (or polarity) of this feature is its Weight (or Polarity) times the parent's effective weight (or polarity).

Returns/sets the polarity of this feature. The polarity of a given feature may be -1, 0(undefined), or +1. Polarities of +1 or -1 define where to find brighter pixels relative to the feature geometry, and 0 means undefined.

Returns the complete set of state flags supported on this object. The flags may be indexed by name as shown in the following C# code snippet: if (changedObject.StateFlags["Color"] & eventArgs.StateFlags) { ... }

Returns/sets the weight of this feature. The weight of a feature determines its relative importance compared to other features of the model. The weight defaults to 1.0.

This event is raised when one or more parts of the object's state may have changed.
