Each time evidence is shared from the source case Evidence Broker invokes the case type specific Evidence Sharing Strategy. This allows, at a case type level, flexibility in deciding how the sharing should take place. A default sharing strategy that is appropriate for most situations is included out of the box. Custom implementation of the sharing strategy can institute a consent model that uses customer specific logic to determine if a particular evidence can be shared and also decide on specific targets that it can be shared with. The transport mechanism of changes from source to the target can also be modified using a custom strategy.
To facilitate easy creation of new strategies a helper class ProcessEvidenceHelper has been provided. This class contains reusable code and provides various helper functions thought to be useful in creating a new strategy.
