This change allows the user to use a simple query syntax in the search field to filter the results using names,
operators and predefined filters.
The class QueryTree is capable of parsing a simple query language consiting of QueryNodes, subclassed as
QueryOperators, QueryCommands and QueryTokens. QueryToken identifies a Token by name. QueryCommand represents predefined
filters. QueryOperator defines the syntactic relationship.
QueryNode examples:
"A" -> QueryToken that identifies the Token named A
class -> QueryCommand that filters all Nodes that are classes
. -> QueryOperator that concatenates filters
QueryExamples:
"A".class -> All Tokens named A that are classes
method.(private|protected) -> All methods that are private or protected
"A".member -> All members of A
"A":field.!const -> All fields of A that are not const (':' can be used instead of '.member')
QueryTree checks for correct operator precedence and validity of the query.
All QueryCommands can be found in data/query/QueryCommand.cpp
All QueryOperators can be found in data/query/QueryOperator.cpp
The parsed QueryTree is then passed to the class GraphFilterConductor, which is capable of applying the query on a
Graph. Each part of the query gets assigned a GraphFilter that filters the input Graph in order of node precedence. The
class SubGraph is used as intermediate container, only holding bare pointers to Nodes and Edges. The output Graph holds
all Nodes that match the query.
MessageActivateTokens is used to show all of the results in the CodeView. The GraphView currently only shows the first
Node of the results.
bug id = #6
* Annotations updated when active token Id changes
* FileName in window title
* Maximize button not shown
* Scrolls roughly to the maximized location.
* Maximizing also on double click in code snippet
Moved Storage instantiation into the Project. Storage access is still handled via the GraphAccess and LocationAccess
interfaces, but the ComponentFactory now only serves proxy implementations of these access classes. Project is
responsible for setting the subject of the proxies to the current Storage instance.
* activate token of most nested location
* show parts of locations with start or end outside of snippet
* (fix for multiple parsing of function and method bodies)
- Renamed MessageActivateTokenLocation to MessageActivateToken, since it uses the Token id (not the TokenLocation id).
- Implemented CodeController to add one snippet for each location where the activated token occurred.
- Added Semaphore to QtThreadedFunctor to prevent an evil race-condition.
- CodeView dispatches message when a token is clicked.
Added some features to QTCodeSnippet:
* Code is now annotated using information from TokenLocationFile
* Start of line numbering can be set
* Clicking on an annotation in the code gives the corresponding Token Id

- Replaced CodeAccess with LocationAccess.
- Implemented basic functionality for CodeController.
- Added messaging to the project.
- Added QtThreadedFunctor to enable our Messaging thread to invoke calls on the QtThread.
- Added GraphController.
