Examples of org.apache.derby.catalog.IndexDescriptor

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.
