Examples of OIndexCursor

com.orientechnologies.orient.core.index.OIndexCursor
Presentation of OrientDB index cursor for point and range queries. Cursor may iterate by several elements even if you do point query (query by single key). It is possible if you use not unique index. Contract of cursor is simple it iterates in some subset of index data till it reaches it's borders in such case {@link #nextEntry()} returns null.Cursor is created as result of index query method such as {@link com.orientechnologies.orient.core.index.OIndex#iterateEntriesBetween(Object,boolean,Object,boolean,boolean)} cursorinstance can not be used at several threads simultaneously. @author Andrey Lomakin Andrey Lomakin @since 4/4/14
