malte_langkabel e628241b02 data: database storage
* replaced storage by a new version that utilizes sqlite for persistence.
* added SqliteStorage to manage direct access to the database.
* added testsuit for sqlite.
* slimmed down the protected interface of the storage.
* changed tests in StorageTestSuit to avoid using protected methods of the storage.
* added functions to begin and commit a transaction to the storage.
* removed GraphFilterTestSuite.
* removed GraphFilterConductorTestSuite.
* added Node and Edge constructor that takes id as parameter
* added constructor for TokenComponentNameCached that accepts NameHierarchy as parameter
* added TokenLocation constructor that takes locationId as parameter.
* created respective construction functions in TokenLocatonLine, -File and -Collection.

malte_langkabel e17341fc43 data: parse partial template specializations
* fixed: implicit template specializations will be found even if the original template definition is located in a different file (that gets included).
* implemented correct extraction of template parameters, template arguments and template specialization edges.
* added token locations for template parameters of partial template specializations.
* graph view displays full names of template parameters and template arguments.
* added test code for features

Eberhard Graether 2c84bf20ed data: split off inner classes of SearchIndex 2014-10-28 22:06:22 +01:00
Eberhard Graether 86f4629b0d logic: preselecting SearchNodes for autocompletion by prefiltering the Graph with the entered Query
This change only shows matches in the autocompletion list that are prefiltered by the already entered query. The
autocompletion now also shows up after an operator of type . or > has been entered to show an alphabetical list of
possible tokens.

Eberhard Graether 4fd1f330ed data: added SearchIndex for fuzzy name search and rewrote name handling in the Storage
This change stores each Token name in the separate singleton class Dictionary. The Dictionary gives each saved word an
Id and thereby avoids duplicated names. E.g if the constructor method "Graph::Graph" is stored then the word "Graph"
only appears once in memory.

The class SearchIndex is now responsible for the name hierarchy and is instantiated by the Storage. The SearchIndex
builds the name hierarchy using SearchNodes, each holding a Dictionary string reference of the name it holds. E.g if the
names "math::ceil" and "math::floor" are added to the SearchIndex then 3 nodes get created, the SearchNode "math" will
hold the two childs "ceil" and "floor".

The hierarchical graph creation functionality got split off from Graph into the new subclass StorageGraph. The
StorageGraph creates nodes with a passed SearchNode pointer of the name it represents in the SearchIndex. Thereby the
StorageGraph reuses the hierarchical information in the SearchIndex and can create nodes much quicker by avoiding node
searches and name comparisions.

The name information is now stored in the Nodes via the TokenComponentName class, which is subclassed into
TokenComponentNameReferenced and TokenComponentNameCached. The StorageClass creates nodes with the component
TokenComponentNameReferenced, which holds a pointer to the SearchNode instance holding the name. This allows for
retrieving the full name of the node, without using other Nodes int the Graph, which might not be present. If the Node
is copied then the component changes to a TokenComponentNameCached, which holds the full name as a string, so the
memory in the Storage doesn't have to be accessed anymore.

TokenComponentSignature is now only holding an Id of the signature string saved in the Dictionary, which speeds up the
signature comparison. A follow-up will change saving the whole signature as string to reusing the wordIds it is
consisting of.

Lastly the SearchIndex holds basic fuzzy search functionality. A passed query gets compared down the SearchNode
hierarchy as long as matches for each letter are found. Matches must contain all letters of the query. The search is
case-insensitive. If letters are found in front positions, next to each other or written in uppercase they are weighed
higher in the match ranking. The character ':' is also interpreted and found, although the '::' delimiter is not stored.

E.g. the query "m:l" used on the example above will return both "math::floor" and "math::ceil", but "floor" is ranked
higher because the 'l' appears closer to the start.
