Interface RelationTagParser

All Superinterfaces:

TagParser

All Known Implementing Classes:

OSMBikeNetworkTagParser, OSMFootNetworkTagParser

public interface RelationTagParser
extends TagParser

This interface serves the purpose of creating relation flags (max. 64 bits) from ReaderRelation in handleRelationTags and then allows converting the relation flags into the edge flags. A direct conversion of ReaderRelation into edge flags is not yet possible yet due to storage limitation of the 'supervisor' OSMReader. See #1775.

Method Summary

Modifier and Type	Method and Description
void	createRelationEncodedValues(EncodedValueLookup lookup, List<EncodedValue> registerNewEncodedValue)
IntsRef	handleRelationTags(IntsRef relFlags, ReaderRelation relation) Analyze the tags of a relation and create the routing flags for the second read step.

Method Detail

createRelationEncodedValues

void createRelationEncodedValues(EncodedValueLookup lookup,
                                 List<EncodedValue> registerNewEncodedValue)

handleRelationTags

IntsRef handleRelationTags(IntsRef relFlags,
                           ReaderRelation relation)

Analyze the tags of a relation and create the routing flags for the second read step. In the pre-parsing step this method will be called to determine the useful relation tags.
