Method Detail

resolve

public org.openstreetmap.atlas.geography.atlas.change.FeatureChange resolve(org.openstreetmap.atlas.geography.atlas.change.FeatureChange left,
                                                                            org.openstreetmap.atlas.geography.atlas.change.FeatureChange right,
                                                                            java.util.Map<java.lang.String,java.io.Serializable> configuration)

Perform the resolution. At the moment, we do a basic resolution that tries to apply as many filters as possible. If the number that apply is not exactly 1, we fail. If both the left and right FeatureChange apply for a given rule, we decide what to do based on the leftRightExclusivity parameter. In the future, this method may respect the other parameters as well. For now, we will see what the data looks like using this simple resolution.

Specified by:

resolve in interface MergeForgivenessStrategy

Parameters:

left - the left FeatureChange

right - the right FeatureChange

configuration - the associated configuration Map

Returns:

the selected FeatureChange
