CogVisionDataContainer Class

Cognex VisionPro 9.21

This class is a general purpose container of vision data. Each element in this container has both a string key and a value of type ICogVisionData. This container maintains an ordered list of these key value pairs. A particular ICogVisionData value may be referenced by integer index as in a list, or by string key as in a dictionary. The keys must all be unique, non-null, non-empty strings. In addition, this class implements the ICogVisionData interface.

Constructors

	Name	Description
	CogVisionDataContainer	Default construct a CogVisionDataContainer.

	GetRangeGreyImagePairs( CogImage16Range , CogImage16Grey )
	GetRangeGreyImagePairs( CogImage16Range , CogImage16Grey , String )	This method steps through the top level elements in the container. For every element that is itself a container holding exactly one CogImage16Range and exactly one CogImage16Grey (and possibly some other objects), copy a reference to that range image into the output array of CogImage16Range references. And copy a reference to the grey image into the output array of CogImage16Grey. And copy the associated top level dictionary key string into the output array of string references.

	GetRangeImages( CogImage16Range )
	GetRangeImages( CogImage16Range , String )	This method steps through the top level elements in this container and copies a reference to every CogImage16Range that it finds into an output array of CogImage16Range references.

	ResumeAndRaiseChangedEvent	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. (Inherited from CogSerializableChangedEventBase.)
	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. (Inherited from CogSerializableChangedEventBase.)

	PairIndexer	Gets or sets the key value pair at the specified index. The key is a string and the value is an ICogVisionData reference.
	StateFlags	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) { ... } (Inherited from CogSerializableChangedEventBase.)
