getIndexName

protected String getIndexName()

Description copied from class: PrimitiveTypeBase

Return the name of the DB index to create for the primitive values.

Specified by:

getIndexName in class PrimitiveTypeBase<HGHandle>

readBytes

protected HGHandle readBytes(byte[] data,
                 int offset)

Specified by:

readBytes in class PrimitiveTypeBase<HGHandle>

writeBytes

protected byte[] writeBytes(HGHandle value)

Specified by:

writeBytes in class PrimitiveTypeBase<HGHandle>

getComparator

public Comparator<byte[]> getComparator()

Description copied from interface: HGPrimitiveType

Return a java.util.Comparator instance that provides an order relation of the values of the primitive type. An implementation is allowed to return null in which case it is assumed that the type does not offer an ordering relation. However, if a non-null value is returned, it is must be of a publicly available and default constructible class.
