Specified by:

getName in interface org.openstreetmap.atlas.utilities.runtime.FlexibleSubCommand

getDescription

public java.lang.String getDescription()

Specified by:

getDescription in interface org.openstreetmap.atlas.utilities.runtime.FlexibleSubCommand

switches

public org.openstreetmap.atlas.utilities.runtime.Command.SwitchList switches()

Specified by:

execute

public int execute(org.openstreetmap.atlas.utilities.runtime.CommandMap command)

Specified by:

mapFeatures

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

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

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)

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.

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)

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

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
