Interface Summary

Interface	Description
CriteriaAccessor<T>	Resolves the criteria object from given KeyValueQuery.
IdentifierGenerator	API for components generating identifiers.
KeyValueAdapter	KeyValueAdapter unifies access and shields the underlying key/value specific implementation.
KeyValueCallback<T>	Generic callback interface for code that operates on a KeyValueAdapter.
KeyValueOperations	Interface that specifies a basic set of key/value operations.
SortAccessor<T>	Resolves the Sort object from given KeyValueQuery and potentially converts it into a store specific representation that can be used by the QueryEngine implementation.

Class Summary

Class	Description
AbstractKeyValueAdapter	Base implementation of KeyValueAdapter holds QueryEngine to delegate find and count execution to.
ForwardingCloseableIterator<T>	Forwards CloseableIterator invocations to the configured Iterator delegate.
IterableConverter	Converter capable of transforming a given Iterable into a collection type.
KeyValuePersistenceExceptionTranslator	Simple PersistenceExceptionTranslator implementation for key/value stores that converts the given runtime exception to an appropriate exception from the org.springframework.dao hierarchy.
KeyValueTemplate	Basic implementation of KeyValueOperations.
QueryEngine<ADAPTER extends KeyValueAdapter,CRITERIA,SORT>	Base implementation for accessing and executing KeyValueQuery against a KeyValueAdapter.
SpelCriteria	SpelCriteria allows to pass on a SpelExpression and EvaluationContext to the actual query processor.
SpelPropertyComparator<T>	Comparator implementation using SpelExpression.
SpelSortAccessor	SortAccessor implementation capable of creating SpelPropertyComparator.

Exception Summary
