类概要

类	说明
BaseIndex	Most index implementations extend the base index.
FunctionCursor	A cursor for a function that returns a result.
FunctionCursorResultSet	A cursor for a function that returns a JDBC result set.
FunctionIndex	An index for a function that returns a result set.
HashIndex	An unique index based on an in-memory hash map.
IndexCondition	A index condition object is made for each condition that can potentially use an index.
IndexCursor	The filter used to walk through an index.
IndexType	Represents information about the properties of an index
LinkedCursor	The cursor implementation for the linked index.
LinkedIndex	A linked index is a index for a linked (remote) table.
MetaCursor	An index for a meta data table.
MetaIndex	The index implementation for meta data tables.
MultiVersionCursor	The cursor implementation for the multi-version index.
MultiVersionIndex	A multi-version index is a combination of a regular index, and a in-memory tree index that contains uncommitted changes.
NonUniqueHashCursor	Cursor implementation for non-unique hash index
NonUniqueHashIndex	A non-unique index based on an in-memory hash map.
PageBtree	A page that contains index data.
PageBtreeCursor	The cursor implementation for the page b-tree index.
PageBtreeIndex	This is the most common type of index, a b tree index.
PageBtreeLeaf	A b-tree leaf page that contains index data.
PageBtreeNode	A b-tree node page that contains index data.
PageDataIndex	The scan index allows to access a row by key.
PageDataLeaf	A leaf page that contains data of one or multiple rows.
PageDataNode	A leaf page that contains data of one or multiple rows.
PageDataOverflow	Overflow data for a leaf page.
PageDelegateIndex	An index that delegates indexing to the page data index.
PageIndex	A page store index.
RangeIndex	An index for the SYSTEM_RANGE table.
ScanCursor	The cursor implementation for the scan index.
ScanIndex	The scan index is not really an 'index' in the strict sense, because it can not be used for direct lookup.
SingleRowCursor	A cursor with at most one row.
SpatialTreeIndex	This is an index based on a MVR-TreeMap.
TreeCursor	The cursor implementation for a tree index.
TreeIndex	The tree index is an in-memory index based on a binary AVL trees.
ViewCursor	The cursor implementation of a view index.
