com.orchestranetworks.service.extensions.AdaptationTreeOptimizerSpec_MutualizeCommons

public class AdaptationTreeOptimizerSpec_MutualizeCommons
extends AdaptationTreeOptimizerSpec

Specifies an optimization that refactors common values in a dataset tree.

The optimization is performed by comparing each value in the specified dataset to the values in its children:

1. Every node is checked; if all children have a common value, this common value is set in their parent, and all child values become inherited.
2. The above rule only applies if it does not modify the resolved view of a dataset, if resolved view is activated.

For tables, it compares each child node of each record to the record with the same primary key in the parent node.

Constructor Detail

AdaptationTreeOptimizerSpec_MutualizeCommons

public AdaptationTreeOptimizerSpec_MutualizeCommons(Adaptation aDataSet,
                                                    boolean includeAllDescendants)

Creates a specification for factoring common values in a dataset tree.

If the parameter includeAllDescendants is set to false, the optimization will only handle the specified dataset and its children.

Parameters:

aDataSet - top parent to be targeted by the optimization of the dataset tree.

includeAllDescendants - includes all datasets, even children of delegated datasets.

public AdaptationTreeOptimizerIterator createOptimizerIterator(Session aSession)

Description copied from class: AdaptationTreeOptimizerSpec

Builds an iterator for dataset tree optimization.

Specified by:

createOptimizerIterator in class AdaptationTreeOptimizerSpec

Parameters:

aSession - session for running the optimization.
