All Implemented Interfaces:

BOp, IPropertySet, Serializable, Cloneable

public class InlineMaterializeOp<E>
extends PipelineOp

This operator is used as part of the BigdataValue materialization step inside the pipeline. Inline IVs are routes to this bop to be materialized and have their BigdataValue cached on them. The inline IVs need access to the LexiconRelation to materialize themselves, but only to the class itself, not to the data in its indices. The lexicon's LexiconConfiguration is used by the ExtensionIVs in the materialization process.

eval

public FutureTask<Void> eval(BOpContext<IBindingSet> context)

Description copied from class: PipelineOp

Return a FutureTask which computes the operator against the evaluation context. The caller is responsible for executing the FutureTask (this gives them the ability to hook the completion of the computation).

Specified by:

eval in class PipelineOp

Parameters:

context - The evaluation context.

Returns:

The FutureTask which will compute the operator's evaluation.
