Class MappedDecimalEncodedValue

java.lang.Object

com.graphhopper.routing.profiles.SimpleIntEncodedValue

com.graphhopper.routing.profiles.MappedDecimalEncodedValue

All Implemented Interfaces:

DecimalEncodedValue, EncodedValue, IntEncodedValue

public final class MappedDecimalEncodedValue
extends SimpleIntEncodedValue
implements DecimalEncodedValue

For certain values it can be more efficient to store the mapping instead of the value and a factor. E.g. for "maximum height of a road" there might be only a few distinct values where we need full precision.
