com.thinkaurelius.titan.graphdb.database.serialize.attribute.AbstractDecimal

com.thinkaurelius.titan.core.attribute.Precision

All Implemented Interfaces:

Serializable, Comparable<AbstractDecimal>

public class Precision
extends AbstractDecimal

Data type for a decimal value that can be used in the definition of a PropertyKey instead of using Double since precision values have a fixed number of decimals places, namely 6, and as such allow for order preserving serialization. In other words, use this data type when only up to 6 decimal places are needed and ordering is important in the definition of vertex centric indices.
