PropagationHandler (Broadleaf Data Tracking Core 1.7.1-GA API)

All Superinterfaces:

org.springframework.core.Ordered, PropagationAware

All Known Implementing Classes:

DefaultPropagationHandler, VendorSandboxPropagationHandler
```
public interface PropagationHandler
extends PropagationAware, org.springframework.core.Ordered
```
Perform catalog propagation of entity changes post deployment, iterating through the catalog inheritance hierarchy. Handlers participate as part of the operation of PropagationManager. Handlers are ordered in the manager component, and the first handler capable of handling the request for propagation wins and other handlers are ignored. Altered, or special propagation behavior may be introduced in this way by adding handlers with higher precedence ordering.

```
boolean canHandle(Trackable incoming,
                  String incomingCatalog,
                  String parentCatalog,
                  @Nullable
                  Trackable candidate,
                  OperationType changeType)
```
    Is this handler capable of handling the propagation process given the contextual information.
    
    Parameters:
    
    incoming - The Trackable instance that contains the change information to propagate
    
    incomingCatalog - The current catalog in which the propagation is occuring
    
    parentCatalog - The parent catalog up one level
    
    candidate - The candidate, if available, representing a catalog override already existing in the incomingCatalog.
    
    changeType - The type of change requested. See OperationType.
    
    Returns:
    
    Is this handler capable of handling the propagation process
