Package org.apache.uima.cas.impl
Class XmiSerializationSharedData
java.lang.Object
org.apache.uima.cas.impl.XmiSerializationSharedData
A container for data that is shared between the
XmiCasSerializer
and the
XmiCasDeserializer
. This has a number of uses:
- Consistency of xmi:id values across serializations. If you pass an
XmiSerializationSharedData
instance to the deserializer, the deserializer will store information about the incoming xmi:id values. If you then pass the sameXmiSerializationSharedData
object to the serializer when you attempt to serialize the same CAS, all of the incoming FS will be serialized using the same xmi:id value that they had when they were deserialized. - Support for "out-of-typesystem data". If you call the XMI deserializer with the
lenient
parameter set to true, whenever it encounters an XMI element that doesn't correspond to a type in the type system, it will populate theXmiSerializationSharedData
with information about these elements. If you then pass the sameXmiSerializationSharedData
object to the serializer when you attempt to serialize the same CAS, these out-of-typesystem FS will be reserialized without loss of information. References between in-typesystem and out-of-typesystem FS (in either direction) are maintained as well. - After calling the XmiCasSerializer and passing an
XmiSerializationSharedData
, you can call thegetMaxXmiId()
method to get the maximum xmi:id value in the serialized CAS. This feature, along with the consistency of xmi:id values, allows merging multiple XMI documents into a single CAS. See TODO.
Inner classes are used to hold information about Feature Structure elements, both for out-of-typesystem data, and also when deserializing pre V3 xmi serializations where the Sofa FS are not guaranteed to come before other Feature Structures that depend on them.

Field Details
-
fsToXmiId
V3: FSs have an id - use that. (Assumes id's are internal ones) A map from FeatureStructures to xmi:id. This is populated whenever an XMI element is serialized or deserialized. It is used by the getXmiId() method, which is done to ensure a consistent ID for each FS address across multiple serializations. -
xmiIdToFs
A map from xmi:id to FeatureStructure address. This is populated whenever an XMI element is serialized or deserialized. It is used by the getFsAddrForXmiId() method, necessary to support merging multiple XMI CASes into the same CAS object. -
ootsFs
List of OotsElementData objects, each of which captures information about incoming XMI elements that did not correspond to any type in the type system. -
ootsViewMembers
Map from the xmi:id (String) of a Sofa to a List of xmi:id's (Strings) for the out-of-typesystem FSs that are members of that Sofa's view. -
ootsFeatures
Map from Feature Structures to OotsElementData object, capturing information about out-of-typesystem features that were part of an in-typesystem FS. These include both features not defined in the typesystem and features that are references to out-of-typesystem elements. This information needs to be included when the FS is subsequently serialized. -
ootsArrayElements
V3: Key is FSArray Map from an FSArray to a list ofXmiSerializationSharedData.XmiArrayElement
objects, each of which holds an index and an xmi:id for an out-of-typesystem array element. -
maxXmiId
private int maxXmiIdThe maximum XMI ID used in the serialization. Used to generate unique IDs if needed.
