The resolver instance must be explicitly released using releaseValueResolver(ValueResolver).

Parameters:

resolverId - The resolver ID

Returns:

The corresponding ValueResolver; null if the resolver could not be instantiated

releaseValueResolver

void releaseValueResolver(ValueResolver resolver)

Releases the specified ValueResolver.

Parameters:

resolver - The resolver to release

acquireAggregate

Aggregate acquireAggregate(String aggregateId)

Acquires an Aggregate for the specified aggregate ID.

The aggregate must be explicitly released using releaseAggregate(Aggregate).

Parameters:

aggregateId - The aggregate ID

Returns:

The corresponding Aggregate; null if the aggregate could not be instantiated

releaseAggregate

void releaseAggregate(Aggregate aggregate)

Releases the specified Aggregate.

Parameters:

aggregate - The aggregate to release

acquireValueExtractor

ValueExtractor acquireValueExtractor(String extractorId)

Acquires a ValueExtractor for the specified extractor ID.

The extractor must be explicitly released using releaseExtractor(ValueExtractor).

Parameters:

extractorId - The extractor ID

Returns:

The corresponding ValueExtractor; null if the extractor could not be instantiated

releaseExtractor

void releaseExtractor(ValueExtractor extractor)

Releases the specified ValueExtractor.

Parameters:

extractor - The extractor to release

acquireFilter

Filter acquireFilter(String filterId)

Acquires a Filter for the specified filter ID.

The filter must be explicitly released using releaseFilter(Filter).

Parameters:

filterId - The filter ID
