- Method Detail
  - schemaSourceEncountered
```
void schemaSourceEncountered(org.opendaylight.yangtools.yang.model.repo.api.SchemaSourceRepresentation source)
```
    Invoked when the registry sees a concrete source. This callback is typically used by cache-type listeners, who intercept the source, store it locally and announce themselves as a provider of that particular schema source.
    
    Parameters:
    
    source - Schema source
  - schemaSourceRegistered
```
void schemaSourceRegistered(Iterable<PotentialSchemaSource<?>> sources)
```
    Invoked when a new schema source is registered by a provider. This call callback, along with schemaSourceUnregistered(PotentialSchemaSource) is typically used by transformer-type listeners, who intercept the registration if the advertised representation matches their input type and register themselves as a potential provider of the same source in their output representation type.
    
    Parameters:
    
    sources - Newly available sources
  - schemaSourceUnregistered
```
void schemaSourceUnregistered(PotentialSchemaSource<?> source)
```
    Invoked when a schema source is unregistered.
    
    Parameters:
    
    source - Schema source representation
