com.thinkaurelius.titan.core.attribute.Decimal

All Implemented Interfaces:

Serializable, Comparable<AbstractDecimal>

public class Decimal
extends AbstractDecimal

Data type for a decimal value that can be used in the definition of a PropertyKey instead of using Double since decimals have a fixed number of decimals places, namely 3, and as such allow for order preserving serialization. In other words, use this data type when only up to 3 decimal places are needed and ordering is important in the definition of vertex centric indices.
