Field Detail

DEFAULT_FORMAT

public static final XMLFormat DEFAULT_FORMAT

The format this deserializer will read if unspecified at construction. This defaults to the latest FOXML format.

Constructor Detail

METSFedoraExtDODeserializer

public METSFedoraExtDODeserializer()

Creates a deserializer that reads the default Fedora METS Extension format.

METSFedoraExtDODeserializer

public METSFedoraExtDODeserializer(XMLFormat format)

Creates a deserializer that reads the given Fedora METS Extension format.

Parameters:

format - the version-specific Fedora METS Extension format.

Throws:

IllegalArgumentException - if format is not a known Fedora METS Extension format.

Method Detail

getInstance

public DODeserializer getInstance()

Creates a new deserializer that the same format as this one.

Specified by:

getInstance in interface DODeserializer

deserialize

public void deserialize(InputStream in,
                        DigitalObject obj,
                        String encoding,
                        int transContext)
                 throws ObjectIntegrityException,
                        StreamIOException,
                        UnsupportedEncodingException

Deserializes the given stream.

Specified by:

deserialize in interface DODeserializer

Parameters:

in - the stream to read from (closed when finished).

obj - the object to deserialize into.

encoding - the character encoding if the format is text-based.

transContext - the translation context.

Throws:

ObjectIntegrityException - if the stream does not properly encode an object.

StreamIOException - if there is an error reading from the stream.

UnsupportedEncodingException - if the encoding is not supported by the JVM.
