Method Detail

getSerializer

public OpenmrsSerializer getSerializer(java.lang.Class<? extends OpenmrsSerializer> serializationClass)

Description copied from interface: SerializationService

Returns the serializer that matches the passed class, or null if no such serializer exists.

Specified by:

getSerializer in interface SerializationService

Parameters:

serializationClass - - the serialization class to retrieve

Returns:

OpenmrsSerializer that matches the passed class

See Also:

SerializationService.getSerializer(java.lang.Class)

getDefaultSerializer

public OpenmrsSerializer getDefaultSerializer()

Description copied from interface: SerializationService

Returns the default serializer configured for the system. This enables a user to serialize objects without needing to know the underlying serialization implementation class.

Specified by:

getDefaultSerializer in interface SerializationService

Returns:

OpenmrsSerializer the default configured serializer

See Also:

SerializationService.getDefaultSerializer()

serialize

public java.lang.String serialize(java.lang.Object o,
                                  java.lang.Class<? extends OpenmrsSerializer> clazz)
                           throws SerializationException

Description copied from interface: SerializationService

Serialize the passed object into an identifying string that can be retrieved later using the passed OpenmrsSerializer class

Specified by:

serialize in interface SerializationService

Parameters:

o - - the object to serialize

clazz - - the OpenmrsSerializer class to use for serialization

Returns:

String representing this object

Throws:

SerializationException

See Also:

SerializationService.serialize(java.lang.Object, java.lang.Class)

deserialize

public <T> T deserialize(java.lang.String serializedObject,
                         java.lang.Class<? extends T> objectClass,
                         java.lang.Class<? extends OpenmrsSerializer> serializerClass)
              throws SerializationException

Description copied from interface: SerializationService

Deserialize the given string into a full object using the given OpenmrsSerializer class

Specified by:

deserialize in interface SerializationService

Parameters:

serializedObject - - String to deserialize into an Object

objectClass - - The class to deserialize the Object into

serializerClass - - The OpenmrsSerializer class to use to perform the deserialization

Returns:

hydrated object of the appropriate type

Throws:

SerializationException

See Also:

SerializationService.deserialize(java.lang.String, java.lang.Class, java.lang.Class)

getSerializers

public java.util.List<? extends OpenmrsSerializer> getSerializers()

Description copied from interface: SerializationService

Gets the list of OpenmrsSerializers that have been registered with this service.

Modules are able to add more serializers by adding this in their moduleApplicationContext. e.g.:

        <bean parent="serializationServiceTarget">
                <property name="serializers">
                <list>
                        <ref bean="xstreamSerializer"/>
                </list>
                </property>
  </bean>
  <bean id="xstreamSerializer" class="org.openmrs.module.serialization.xstream.XStreamSerializer"/>
 

Specified by:

getSerializers in interface SerializationService

Returns:

the serializers

setSerializers

public void setSerializers(java.util.List<? extends OpenmrsSerializer> serializers)

Parameters:

serializers - the serializers to set

Expected behavior:

not reset serializers list when called multiple times
