Method Detail

deserialize

protected Counter deserialize(java.lang.String redisKey,
                  java.lang.String v)

Description copied from class: AbstractRedisRepository

Deserialize from the String representation to the domain object.

Specified by:

deserialize in class AbstractRedisRepository<Counter,java.lang.String>

Parameters:

redisKey - the entity id

v - the serialized representation of the domain object

serialize

protected java.lang.String serialize(Counter entity)

Description copied from class: AbstractRedisRepository

Provide a String representation of the domain entity.

Specified by:

serialize in class AbstractRedisRepository<Counter,java.lang.String>

keyFor

protected java.lang.String keyFor(Counter entity)

Description copied from class: AbstractRedisRepository

Return the entity id for the given domain object.

Specified by:

keyFor in class AbstractRedisRepository<Counter,java.lang.String>

serializeId

protected java.lang.String serializeId(java.lang.String id)

Description copied from class: AbstractRedisRepository

Return a String representation of the domain ID. Note that order should be preserved between ID domain and String representation.

Specified by:

serializeId in class AbstractRedisRepository<Counter,java.lang.String>

deserializeId

protected java.lang.String deserializeId(java.lang.String string)

Description copied from class: AbstractRedisRepository

Deserialize an entity id from its String representation.

Specified by:

deserializeId in class AbstractRedisRepository<Counter,java.lang.String>

increment

public long increment(java.lang.String name)

Description copied from interface: CounterRepository

Increment the given counter by one, creating it if it did not exist. Implementations which can do this atomically in one operation are encouraged to do so.

Specified by:

increment

public long increment(java.lang.String name,
             long amount)

Description copied from interface: CounterRepository

Specified by:

increment in interface CounterRepository

decrement

public long decrement(java.lang.String name)

Description copied from interface: CounterRepository

Decrement the given counter, creating it if it did not exist. Implementations which can do this atomically in one operation are encouraged to do so.

Specified by:

decrement in interface CounterRepository

reset

public void reset(java.lang.String name)

Description copied from interface: CounterRepository

Reset the given counter to zero.

Specified by:

reset in interface CounterRepository
