Method Details

getSource

public ListenableFuture<? extends T> getSource(SourceIdentifier sourceIdentifier)

Description copied from interface: SchemaSourceProvider

Returns a representation a for supplied YANG source identifier. The resolution criteria are as follows:

• If the source identifier specifies a revision, this method returns either a representation of that particular revision or throw MissingSchemaSourceException.
• If the source identifier does not specify a revision, this method returns the newest available revision, or throws MissingSchemaSourceException.

In either case the returned representation is required to report a non-null revision in the SourceIdentifier returned from SchemaSourceRepresentation.getIdentifier().

Implementations are not required to provide constant behavior in time, notably this different invocation of this method may produce different results.

Specified by:

getSource in interface SchemaSourceProvider<T extends SchemaSourceRepresentation>

Parameters:

sourceIdentifier - source identifier

Returns:

future source representation, if supplied YANG module is available

close

public void close()

Specified by:

close in interface AutoCloseable

offer

protected void offer(T source)

Description copied from class: AbstractSchemaSourceCache

Offer a schema source in requested representation for caching. Subclasses need to implement this method to store the schema source. Once they have determined to cache the source, they should call AbstractSchemaSourceCache.register(SourceIdentifier).

Specified by:

offer in class AbstractSchemaSourceCache<T extends SchemaSourceRepresentation>

Parameters:

source - schema source
