Class DOTranslatorModule

java.lang.Object

org.fcrepo.server.Parameterized

org.fcrepo.server.Pluggable

org.fcrepo.server.Module

org.fcrepo.server.storage.translation.DOTranslatorModule

All Implemented Interfaces:

Constants, DOTranslator

public class DOTranslatorModule
extends Module
implements DOTranslator

DOTranslatorImpl wrapped as a Module.

To configure the DOTranslatorImpl, this module accepts parameters with names starting with serializer_ and deserializer_. The latter part of each parameter name assigns the name of the format (typically a format URI), and the value of the parameter is a fully-qualified class name, denoting a DOSerializer or DODeserializer, respectively.

Constructor Detail

DOTranslatorModule

public DOTranslatorModule(Map<String,String> params,
                  Server server,
                  String role)
                   throws ModuleInitializationException

Creates an instance using the standard Module constructor.

Throws:

ModuleInitializationException

Method Detail

initModule

public void initModule()
                throws ModuleInitializationException

Initializes the Module based on configuration parameters.

Overrides:

initModule in class Module

Throws:

ModuleInitializationException - If initialization values are invalid or initialization fails for some other reason.

deserialize

public void deserialize(InputStream in,
               DigitalObject out,
               String format,
               String encoding,
               int transContext)
                 throws ObjectIntegrityException,
                        StreamIOException,
                        UnsupportedTranslationException,
                        ServerException

Deserializes the given stream.

Specified by:

deserialize in interface DOTranslator

Parameters:

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

out - the object to deserialize into.

format - the format of the stream (typically a format URI).

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.

ServerException - if the translator is unable to deserialize for any other reason.

UnsupportedTranslationException

DOTranslationUtility.DESERIALIZE_INSTANCE

serialize

public void serialize(DigitalObject in,
             OutputStream out,
             String format,
             String encoding,
             int transContext)
               throws ObjectIntegrityException,
                      StreamIOException,
                      UnsupportedTranslationException,
                      ServerException

Serializes the given object.

Specified by:

serialize in interface DOTranslator

Parameters:

in - the object to serialize.

out - where to send the output to (auto-closed when finished).

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

transContext - the translation context.

Throws:

ObjectIntegrityException - if the given object is in such a state that serialization can't be performed.

StreamIOException - if there is an error writing to the stream.

ServerException - if the translator is unable to serialize for any other reason.

UnsupportedTranslationException
