Description

Interface Summary

Association	An association between two maps.
Attribute	Identifies an attribute.
DataDescriptor	Identifies accessible attributes that the DataSerializer.DataAttributeInflatable can retrieve.
EmbeddedType	An EmbeddedType represents a nested, complex object.
KeyDataDescriptor	KeySerializerPlugin plug-ins create a KeyDataDescriptor using the DataDescriptorFactory to identify any attributes that it wants to expose to the eXtreme Scale runtime.
MapDataDescriptor	MapSerializerPlugin plug-ins create a MapDataDescriptor using the DataDescriptorFactory to expose any relationships that it wants to expose to the eXtreme Scale runtime.
ValueDataDescriptor	ValueSerializerPlugin plug-ins create a ValueDataDescriptor using the DataDescriptorFactory to identify any attributes that it wants to expose to the eXtreme Scale runtime.

Class Summary

Package com.ibm.websphere.objectgrid.plugins.io.datadescriptor Description

This package contains the interfaces and classes that allow a serializer to describe describe any queryable or indexable attributes to eXtreme Scale.

Overview

Each DataSerializer implementation can optionally return a DataDescriptor instance to describe any attributes that can be queried or indexed by the eXtreme Scale runtime.

The DataSerializer implementation uses the DataDescriptorFactory to create a DataDescriptor and populate it with attributes. After the DataSerializer is initialized, the eXtreme Scale runtime will retrieve the DataDescriptor from the DataSerializer to determine what attributes are available.

The MapSerializerPlugin implementation uses the DataDescriptorFactory to expose a MapDataDescriptor, which identifies any relationships between maps.
