Method Detail

isApplicable

public double isApplicable(VDomainModelReference reference)

Description copied from interface: DmrSegmentGenerator

Returns a double that expresses if and how suitable this tester is for the given VDomainModelReference.

Specified by:

isApplicable in interface DmrSegmentGenerator

Parameters:

reference - The VDomainModelReference

Returns:

The value indicating how suitable this tester is, DmrSegmentGenerator.NOT_APPLICABLE if it can't work with the given VDomainModelReference.

generateSegments

public java.util.List<VDomainModelReferenceSegment> generateSegments(VDomainModelReference reference)

Description copied from interface: DmrSegmentGenerator

Takes a VDomainModelReference and generates the list of equivalent DMR Segments. Equivalent means that a DMR using the generated segments resolves exactly the same as the given DMR.

The segment generation is side-effect free. This means neither the given DMR nor any of its contained or referenced elements is changed.

Specified by:

generateSegments in interface DmrSegmentGenerator

Parameters:

reference - The VDomainModelReference to generate the segments for

Returns:

The list of generated segments; might return an empty list if the given DMR does not specify any path but never null
