Examples of IndexDescriptor

com.flaptor.hounder.IndexDescriptor
Describes how this index fits into the cluster of indexes. Contains information about how many indexes make up the cluster, and about what part of the documents this index contains. @author Flaptor Development Team
org.apache.derby.catalog.IndexDescriptor
This interface describes an index. It is used in the column SYS.SYSCONGLOMERATES.DESCRIPTOR and describes everything about an index except the index name and the table on which the index is defined. That information is available in the columns NAME and TABLEID of the table SYS.SYSCONGLOMERATES.

org.nasutekds.guitools.controlpanel.datamodel.IndexDescriptor
The class used to describe the index configuration (the normal index: the one used to improve search performance on a given attribute).
