Method Detail

write

public static JarOutputStream write(OutputStream out,
                                    Model model,
                                    Manifest baseManifest,
                                    ModelArchiveWriter.ArtifactProvider provider)
                             throws IOException

Create a model archive. The output stream will not be closed by this method. The caller must call ZipOutputStream.close() or ZipOutputStream.finish() on the return output stream. The caller can add additional files through the return stream. In order to create an archive for a model, each feature in the model must have a name and a version and the model must be valid, therefore ModelUtility.validateIncludingVersion(Model) is called first. If the model is invalid an IOException is thrown.

Parameters:

out - The output stream to write to

model - The model to write

baseManifest - Optional base manifest used for creating the manifest.

provider - The artifact provider

Returns:

The jar output stream.

Throws:

IOException - If anything goes wrong
