Description

Interface Summary

UpdateStrategy	Strategy for merging updates or additional properties.
ValueAddEventProcessor	Interface for a processor of base and delta events in a revision event type.
ValueAddEventService	Service associating handling vaue-added event types, such a revision event types and variant stream event types.
VariantEvent	A variant event is a type that can represent many event types.
VariantPropResolutionStrategy	Strategy for resolving a property against any of the variant types.

Class Summary

PropertyGroupDesc	For use with building groups of event properties to reduce overhead in maintaining versions.
PropertyUtility	Utility for handling properties for the purpose of merging and versioning by revision event types.
RevisionBeanHolder	Holds revisions for property groups in an overlay strategy.
RevisionEventBeanDeclared	Revision event bean for the overlayed scheme.
RevisionEventBeanMerge	Merge-event for event revisions.
RevisionEventType	Event type of revision events.
RevisionGetterParameters	Getter parameters for revision events.
RevisionNestedPropertyGetter	A getter that works on POJO events residing within a Map as an event property.
RevisionPropertyTypeDesc	Property descriptor for use by revision event types to maintain access to revision event properties.
RevisionSpec	Specification for how to build a revision event type.
RevisionStateDeclared	State for the overlay (non-merge) strategy.
RevisionStateMerge	State for merge stratgies.
RevisionTypeDesc	Per-event-type descriptor for fast access to getters for key values and changes properties.
UpdateStrategyBase	Base strategy implementation holds the specification object.
UpdateStrategyDeclared	Strategy for merging update properties using all declared property's values.
UpdateStrategyExists	Strategy for merging update properties using only existing property's values.
UpdateStrategyNonNull	Strategy for merging update properties using only non-null values.
VAERevisionProcessorBase	Base revision processor.
VAERevisionProcessorDeclared	Provides overlay strategy for property group-based versioning.
VAERevisionProcessorMerge	Provides a set of merge-strategies for merging individual properties (rather then overlaying groups).
VAEVariantProcessor	Represents a variant event stream, allowing events of disparate event types to be treated polymophically.
ValueAddEventServiceImpl	Service for handling revision event types.
VariantEventBean	An event bean that represents multiple potentially disparate underlying events and presents a unified face across each such types or even any type.
VariantEventType	Event type for variant event streams.
VariantPropertyDesc	Descriptor for a variant stream property.
VariantPropertyGetterCache	A thread-safe cache for property getters per event type.
VariantPropResolutionStrategyAny	A property resolution strategy that allows any type, wherein all properties are Object type.
VariantPropResolutionStrategyDefault	A property resolution strategy that allows only the preconfigured types, wherein all properties that are common (name and type) to all properties are considered.
VariantSpec	Specification for a variant event stream.
