protected java.util.Map<PrimitiveId,OsmPrimitive>	externalIdMap the map from external ids to read OsmPrimitives.
protected java.util.Map<java.lang.Long,java.util.Collection<RelationMemberData>>	relations Data structure for relation objects
protected Changeset	uploadChangeset
protected java.util.Map<java.lang.Long,java.util.Collection<java.lang.Long>>	ways Data structure for the remaining way objects

Constructor Summary

AbstractReader()

Method Summary

DataSet	getDataSet() Replies the parsed data set
protected void	prepareDataSet()

Field Detail

ds

protected DataSet ds

The dataset to add parsed objects to.

uploadChangeset

protected Changeset uploadChangeset

externalIdMap

protected final java.util.Map<PrimitiveId,OsmPrimitive> externalIdMap

the map from external ids to read OsmPrimitives. External ids are longs too, but in contrast to internal ids negative values are used to identify primitives unknown to the OSM server

ways

protected final java.util.Map<java.lang.Long,java.util.Collection<java.lang.Long>> ways

Data structure for the remaining way objects

relations

protected final java.util.Map<java.lang.Long,java.util.Collection<RelationMemberData>> relations

Data structure for relation objects

Constructor Detail

AbstractReader

public AbstractReader()

Method Detail

getDataSet

public DataSet getDataSet()

Replies the parsed data set

Returns:

the parsed data set

processNodesAfterParsing

protected void processNodesAfterParsing()

Processes the parsed nodes after parsing. Just adds them to the dataset

processWaysAfterParsing

protected void processWaysAfterParsing()
                                throws IllegalDataException

Processes the ways after parsing. Rebuilds the list of nodes of each way and adds the way to the dataset

Throws:

IllegalDataException - thrown if a data integrity problem is detected

processRelationsAfterParsing

protected void processRelationsAfterParsing()
                                     throws IllegalDataException

Completes the parsed relations with its members.

Throws:

IllegalDataException - thrown if a data integrity problem is detected, i.e. if a relation member refers to a local primitive which wasn't available in the data

processChangesetAfterParsing

protected void processChangesetAfterParsing()

prepareDataSet

protected final void prepareDataSet()
                             throws IllegalDataException

Throws:

IllegalDataException
