Interface BulkAttributeLoader

All Known Implementing Classes:

SecureSingleDependencyReducingAggregateLoader

@PublicSpi
public interface BulkAttributeLoader

An optional interface for bulk attribute preloading. If your AttributeLoader implements this interface, then Structure will call its preload(LongSet, ItemForest, AttributeContext) method once before it starts calling loadValue() or loadChildrenValues().

Method Summary

Modifier and Type	Method and Description
void	preload(com.almworks.integers.LongSet rowIds, ItemForest forest, AttributeContext context) This method is called before all calls to loadValue() or loadChildrenValues() in the current calculation.

Method Detail

preload

void preload(@NotNull
             com.almworks.integers.LongSet rowIds,
             @NotNull
             ItemForest forest,
             @NotNull
             AttributeContext context)

This method is called before all calls to loadValue() or loadChildrenValues() in the current calculation. It is given the set of all row IDs for which the values are needed, so that it can load some data more efficiently, e.g. run a JQL query for all relevant issues.

The result can be stored inside the loader instance itself or in the provided AttributeContext.

The current loader's dependencies are not yet loaded at the time of the call.

Parameters:

rowIds - The set of row IDs for which attribute values are needed.

forest - The ItemForest for which attribute values are needed.

context - The context.
