Method Detail

initializeAndReturnManifest

protected Manifest initializeAndReturnManifest()
                                        throws ReaderInitializationException,
                                               IOException

Description copied from class: AbstractManifestReader

Delegated initialization (and return of) Manifest object. Should be implemented in concreate classes which create Manifest from data in file, JAR, etc. Throwing IOException isn't very pretty, but it allows to remove duplication and move conversion IOException to ReaderInitializationException to a superclass. It's only internal method in ManifestReader hierarchy and doesn't complicate cooperation with other classes.

Specified by:

initializeAndReturnManifest in class AbstractManifestReader

Returns:

initialized Manifest object

Throws:

ReaderInitializationException - other (no IO) error during Manifest initialization

IOException - error during Manifest initialization
