org.openstreetmap.atlas.checks.commands.AtlasChecksGeoJSONDiffSubCommand

All Implemented Interfaces:

org.openstreetmap.atlas.utilities.runtime.FlexibleSubCommand

public class AtlasChecksGeoJSONDiffSubCommand
extends JSONFlagDiffSubCommand

Takes 2 sets of atlas-checks geoJSON flag files and reports the number of additions, subtractions, and changed flags from source to target. Optionally, the reported items can be written to new geoJSON files. Additions and subtractions are based on flag ids. Changes are calculated by differences in the Atlas ids of objects in a flag.

Method Detail

mapFeatures

protected void mapFeatures(org.openstreetmap.atlas.streaming.resource.File file,
                           java.util.HashMap map)

Description copied from class: JSONFlagDiffSubCommand

Parses an atlas-checks flag file and maps each flag to its id.

Overrides:

mapFeatures in class JSONFlagDiffSubCommand

Parameters:

file - File containing the flags

map - HashMap to store the mapped flags

getDiff

protected JSONFlagDiffSubCommand.JSONFlagDiff getDiff(java.util.HashMap source,
                                                      java.util.HashMap target,
                                                      JSONFlagDiffSubCommand.DiffReturn returnType)

Description copied from class: JSONFlagDiffSubCommand

Takes two HashMaps containing atlas-checks flags mapped by id. Finds missing elements in the target based on keys. Optionally computes changes in the AtlasObject ids found in each flag.

Overrides:

getDiff in class JSONFlagDiffSubCommand

Parameters:

source - HashMap of the flags to compare from

target - HashMap of the flags to compare to

returnType - JSONFlagDiffSubCommand.DiffReturn; If this is CHANGED the changed attribute of the returned JSONFlagDiffSubCommand.JSONFlagDiff will be populated.

Returns:

an JSONFlagDiffSubCommand.JSONFlagDiff

identicalFeatureIds

protected boolean identicalFeatureIds(com.google.gson.JsonArray sourceArray,
                                      com.google.gson.JsonArray targetArray)

Description copied from class: JSONFlagDiffSubCommand

Helper function for getMissingAndChanged to check for changes in Atlas ids.

Overrides:

identicalFeatureIds in class JSONFlagDiffSubCommand

Parameters:

sourceArray - feature JsonArray to check from

targetArray - feature JsonArray to check to

Returns:

true if all Atlas ids in source are present in target, and visa versa

writeSetToGeoJSON

protected void writeSetToGeoJSON(java.util.Set<com.google.gson.JsonObject> flags,
                                 org.openstreetmap.atlas.streaming.resource.File output)

Description copied from class: JSONFlagDiffSubCommand

Writes a Set of geoJSON atlas-checks flags to a file.

Overrides:

writeSetToGeoJSON in class JSONFlagDiffSubCommand

Parameters:

flags - Set of JsonObjects representing geoJSON flags

output - File to output to
