Detailed Description
An algorithm for linking annotations among objects.
vtkAnnotationLink is a simple source filter which outputs the vtkAnnotationLayers object stored internally. Multiple objects may share the same annotation link filter and connect it to an internal pipeline so that if one object changes the annotation set, it will be pulled into all the other objects when their pipelines update.
The shared vtkAnnotationLayers object (a collection of annotations) is shallow copied to output port 0.
vtkAnnotationLink can also store a set of domain maps. A domain map is simply a table associating values between domains. The domain of each column is defined by the array name of the column. The domain maps are sent to a multi-block dataset in output port 1.
Output ports 0 and 1 can be set as input ports 0 and 1 to vtkConvertSelectionDomain, which can use the domain maps to convert the domains of selections in the vtkAnnotationLayers to match a particular data object (set as port 2 on vtkConvertSelectionDomain).
The shared vtkAnnotationLayers object also stores a "current selection" normally interpreted as the interactive selection of an application. As a convenience, this selection is sent to output port 2 so that it can be connected to pipelines requiring a vtkSelection.

Member Function Documentation
| static vtkAnnotationLink* vtkAnnotationLink::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkAnnotationLayersAlgorithm.
| virtual const char* vtkAnnotationLink::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkAnnotationLayersAlgorithm.
| static int vtkAnnotationLink::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
