Interface SchemaSourceProvider<T extends SchemaSourceRepresentation>

Type Parameters:
T - Schema source representation type provided by this implementation
All Known Implementing Classes:
AbstractSchemaSourceCache, FilesystemSchemaSourceCache, GuavaSchemaSourceCache, SchemaSourceTransformer, SoftSchemaSourceCache, TextToIRTransformer, YangTextSchemaContextResolver, YinTextToDomTransformer
@Beta public interface SchemaSourceProvider<T extends SchemaSourceRepresentation>
Schema source provider implementations take care of resolving a SourceIdentifier into a particular representation of the schema source. Examples of resolution include fetching the source from an external source, opening a classpath resource, or similar.

    Description
    @NonNull ListenableFuture<? extends T>
    getSource(@NonNull SourceIdentifier sourceIdentifier)
    Returns a representation a for supplied YANG source identifier.

  • Method Details

    • getSource

      @NonNull ListenableFuture<? extends T> getSource(@NonNull SourceIdentifier sourceIdentifier)
      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.

      Parameters:
      sourceIdentifier - source identifier
      Returns:
      future source representation, if supplied YANG module is available
      Throws:
      NullPointerException - if sourceIdentifier is null
