org.springframework.xd.store

Class AbstractInMemoryRepository<T,ID extends java.io.Serializable & java.lang.Comparable<ID>>

java.lang.Object

org.springframework.xd.store.AbstractRepository<T,ID>

org.springframework.xd.store.AbstractInMemoryRepository<T,ID>

Type Parameters:

T - the type of things to store

ID - a "primary key" to the things

All Implemented Interfaces:

org.springframework.data.repository.CrudRepository<T,ID>, org.springframework.data.repository.PagingAndSortingRepository<T,ID>, org.springframework.data.repository.Repository<T,ID>, RangeCapableRepository<T,ID>

Direct Known Subclasses:

InMemoryAggregateCounterRepository, InMemoryCounterRepository

public abstract class AbstractInMemoryRepository<T,ID extends java.io.Serializable & java.lang.Comparable<ID>>
extends AbstractRepository<T,ID>
implements org.springframework.data.repository.PagingAndSortingRepository<T,ID>, RangeCapableRepository<T,ID>

Base implementation for an in-memory store, using a Map internally. Default behaviour is to retain sort order on the keys. Hence, this is by default the only sort supported when querying with a Pageable.

                                   boolean toInclusive)

Description copied from interface: RangeCapableRepository

Return entities whose ids range between from and to. Note that it is possible that entities with those exact ids do not exist. If they do exist, the two boolean parameters control whether to include those results or not. A query from x to x returns an empty result, unless both fromInclusive and toInclusive are true.

Specified by:

findAllInRange in interface RangeCapableRepository<T,ID extends java.io.Serializable & java.lang.Comparable<ID>>
