INeedsMaterialization.Requirement	getRequirement() Does the bop always need materialized variables, or can it sometimes operate on inline terms without materialization? If sometimes, we'll run it before the materialization pipeline steps in an effort to avoid unnecessary materialization overhead.

Method Detail

getRequirement

public INeedsMaterialization.Requirement getRequirement()

Description copied from interface: INeedsMaterialization

Does the bop always need materialized variables, or can it sometimes operate on inline terms without materialization? If sometimes, we'll run it before the materialization pipeline steps in an effort to avoid unnecessary materialization overhead. If it fails to evaluate for a particular solution, then it will be run again after the materialization steps for that solution.

Specified by:

getRequirement in interface INeedsMaterialization

accept

public boolean accept(IBindingSet bs)
               throws SparqlTypeErrorException

Description copied from class: XSDBooleanIVValueExpression

Implement this method.

Specified by:

accept in class XSDBooleanIVValueExpression

Parameters:

bs - The source solution.

Returns:

true iff the function accepts the solution.

Throws:

SparqlTypeErrorException
