org.refcodes.logger.impls

Class AbstractCompositeQueryLogger<L extends QueryLogger<T>,T>

java.lang.Object

org.refcodes.logger.impls.AbstractCompositeLogger<L,T>

org.refcodes.logger.impls.AbstractCompositeQueryLogger<L,T>

Type Parameters:

L - The Logger type to be supported. As the AbstractCompositeLogger is being extended to support other Logger types, we have to provide this generic parameter (for example, sub-classes make use of the AbstractCompositeLogger.getLoggers() method to access the encapsulated Logger instances being sub-types of the Logger interface).

T - The type of the Record instances managed by the Logger.

All Implemented Interfaces:

org.refcodes.component.Destroyable, Logger<T>, QueryLogger<T>

Direct Known Subclasses:

AbstractCompositeTrimLogger, CompositeQueryLoggerImpl

public abstract class AbstractCompositeQueryLogger<L extends QueryLogger<T>,T>
extends AbstractCompositeLogger<L,T>
implements QueryLogger<T>

The CompositeQueryLoggerImpl extends the CompositeLoggerImpl with the query logger functionality. In contrast to the #log(Record) method, which is forwarded to exactly one of the encapsulated query logger instances, the #findLogs() method calls are forwarded to all of the encapsulated query logger instances. (in case, partitioning is needed, take a look at the PartedQueryLoggerImpl)

Method Detail

findLogs

public org.refcodes.tabular.Records<T> findLogs()

Description copied from interface: QueryLogger

Retrieves all available Record instances being logged.

Specified by:

findLogs in interface QueryLogger<T>

Returns:

A Records instance containing all available Record instances being logged.

findLogs

public org.refcodes.tabular.Records<T> findLogs(int aLimit)

Description copied from interface: QueryLogger

Retrieves all available Record instances being logged matching the given criteria and restrictions.

Specified by:

findLogs in interface QueryLogger<T>

Parameters:

aLimit - The maximum Record instances contained in the returned Records instance; there may be more Record instances which are not contained in the Records instance in case the Records instance's size is that of the specified limit.

Returns:

A Records instance containing all available Record instances being logged matching the given criteria and restrictions.

findLogs

public org.refcodes.tabular.Records<T> findLogs(org.refcodes.criteria.Criteria aCriteria)

Description copied from interface: QueryLogger

Retrieves all available Record instances being logged matching the given criteria and restrictions.

Specified by:

findLogs in interface QueryLogger<T>

Parameters:

aCriteria - The Criteria to be applied to the Record instances

Returns:

A Records instance containing all available Record instances being logged matching the given criteria and restrictions.
