Method Detail

getCommonTypeMap

protected static Map<String,String> getCommonTypeMap()

Visible for testing only Retrieve a copy of the commonTypeMap

Returns:

a copy of the commonTypeMap

deserializerFor

public static BagDeserializer deserializerFor(Path serializedBag,
                                              BagProfile profile)

Get a BagDeserializer for a given content type. Currently supported are: zip (ZIP_TYPES) - ZipBagDeserializer tar (TAR_TYPES) - TarBagDeserializer tar+gz (GZIP_TYPES) - GZipBagDeserializer

Parameters:

serializedBag - the Bag (still serialized) to get a BagDeserializer for

profile - the BagProfile to ensure that the content type is allowed

Returns:

the BagDeserializer

Throws:

UnsupportedOperationException - if the content type is not supported

RuntimeException - if the BagProfile does not allow serialization

serializerFor

public static BagSerializer serializerFor(String contentType,
                                          BagProfile profile)

Get a BagSerializer for a given content type and BagProfile. It takes both a short form (zip, tar, gzip) and long form (application/zip, application/tar) version for the content type.

Parameters:

contentType - the content type to get a BagSerializer for

profile - the BagProfile used for validating the contentType

Returns:

the BagSerializer

Throws:

RuntimeException - if the contentType is not supported
