Method Details

internalIterator

public Iterator<? extends PrismContainerValueWrapper<C>> internalIterator(long first,
 long count)

Specified by:

internalIterator in class BaseSortableDataProvider<PrismContainerValueWrapper<C extends Containerable>>

doRepositoryIteration

protected Iterator<? extends PrismContainerValueWrapper<C>> doRepositoryIteration(long first,
 long count)

createWrapper

protected PrismContainerValueWrapper<C> createWrapper(C object,
 com.evolveum.midpoint.task.api.Task task,
 OperationResult result)
                                               throws SchemaException

Throws:

SchemaException

createExportWrapper

protected PrismContainerValueWrapper<C> createExportWrapper(C object)

Creates a lightweight wrapper for export purposes. This skips child wrapper creation which is the main performance bottleneck. The wrapper only holds the PrismContainerValue - columns access data via getRealValue().

internalSize

protected int internalSize()

Specified by:

internalSize in class BaseSortableDataProvider<PrismContainerValueWrapper<C extends Containerable>>

detach

public void detach()

Specified by:

detach in interface org.apache.wicket.markup.repeater.data.IDataProvider<C extends Containerable>

Specified by:

detach in interface org.apache.wicket.model.IDetachable

Overrides:

detach in class BaseSearchDataProvider<C extends Containerable,PrismContainerValueWrapper<C extends Containerable>>

supportsIterativeExport

public boolean supportsIterativeExport()

Description copied from class: BaseSearchDataProvider

Returns false by default. Subclasses that implement exportIterative() should override this to return true.

Specified by:

supportsIterativeExport in interface IterativeExportSupport<C extends Containerable>

Overrides:

supportsIterativeExport in class BaseSearchDataProvider<C extends Containerable,PrismContainerValueWrapper<C extends Containerable>>

exportIterative

public void exportIterative(ObjectHandler<PrismContainerValueWrapper<C>> handler,
 com.evolveum.midpoint.task.api.Task task,
 OperationResult result)
                     throws CommonException

Streaming export using JDBC cursor-based streaming. This method does not load all data into memory - uses true JDBC streaming. Streaming is enabled by setting iterationPageSize to -1. Uses lightweight wrapper to skip expensive child wrapper creation.

Specified by:

exportIterative in interface IterativeExportSupport<C extends Containerable>

Overrides:

exportIterative in class BaseSearchDataProvider<C extends Containerable,PrismContainerValueWrapper<C extends Containerable>>

Parameters:

handler - Handler to process each item. Returns true to continue, false to stop.

task - Task for the operation

result - Operation result

Throws:

CommonException - if an error occurs during the search
