Interface Summary

Interface	Description
ContextPartitionSelector	Interface for classes representing a selector for navigating, querying or selecting among context partitions.
ContextPartitionSelectorById	Selects a context partition by providing the context partition id(s).
ContextPartitionSelectorCategory	Selects context partitions for use with a category context by providing a set of labels.
ContextPartitionSelectorFiltered	Selects context partitions by receiving a context partition identifier for interrogation.
ContextPartitionSelectorHash	Selects context partitions based on hash codes, for use with hashed context.
ContextPartitionSelectorNested	Selects context partitions of a nested context by providing selector according to the nested contexts.
ContextPartitionSelectorSegmented	Selector of context partitions for use with segmented contexts, provides a set of partition keys to select.
ContextPartitionStateListener	Listener for context-specific partition-related events.
ContextStateListener	Listener for event in respect to context management.
EPContextPartitionService	Service interface for administration of contexts and context partitions.
