 Abstract
 \layout Standard
 
 The Opie-Pim API provides a powerfull access interface to the PIM (Personal
  Information Management) data which contains your contact information, the
  dates in your calendar tool (in this paper called datebook events) and
  your todo events.
  Beside providing full featured access to this information, it covers the
  real management of this informantion - the access of the databases - from
  the user.
  
 \layout Standard
 
 While starting to read the automatically generated API-documentation, the
  user may be confused by a lot of unnecessary classes and details which
  makes the quick start not as easy as possible.
  Due to the fact that a user will not need most of the details, this paper
  should help to start to become confortable with those details he need to
  solve his problems.

 Introduction
 \layout Standard
 
 Before starting to jump into the work, we should introduce some specialties
  of the PIM API, first.
  To know these facts should help to avoid possible irritations and misunderstand
 ings:
 \layout Enumerate
 
 The PIM-API heavily uses C++ templates (as known as generic classes), but
  you don't have to understand very deeple what templates are doing and how
  they work! Most of the API works without even seeing the templates.
  In some cases we have to use them (for instance to use the factory classes),
  but this guide will provide examples which should help to find the path
  through.
  But it is a good idea to read some short introduction of templates to avoid
  unnecessary mistakes.
 \layout Enumerate
 
 The PIM-API is split into two parts: The 
 \emph on 
 frontend
 \emph default 
  and the 
 \emph on 
 backend.
 
 \emph default 
  While the frontend provides the API for the user, the backend implements
  how to access the databases and what to do with the data.
  As we just want to access data, this paper just focuses the frontend.
  Thus, you should ignore all classes which contains something like

  easy as possible.

  the PIM data.

 Quick Guide to access the Database
 \layout Standard
 
 In this chapter we will introduce very quickly how to get access to the
  database and how to access data.
  It should help to find the right directions.
  If it is too short for you, you should read the next chapter afterwards
  to find a more complete and detailed view into the system.

 Instantiate the access-object
 \begin_inset LatexCommand \label{sec:Instantiate-the-Access}
 
 \end_inset 
 
 
 \layout Standard
 
 To gain access to the database you need something we will call
 \emph on 
  access-object
 \emph default 
  (an instance of the access-class for the database) which handles the database
  access.
  Requesting such an object is very easy by using the operation 
 \emph on 
 defaultAccess()
 \emph default 
  of the factory class

  (see 
 \begin_inset LatexCommand \url{http://www.sra.uni-hannover.de/~eilers/apidocs/pim2/html/classOpie_1_1OPimAccessFactory.html}

 ).
  This operation is defined like this:

+T* defaultAccess ( 
+\newline 
+typename OPimGlobal::PimType type,
+\newline 
+const QString &appName)
 \layout Standard
 
 You just have to add the following lines to your source code to use it (this
  example is for accessing the contact database):
 \layout LyX-Code
 
+\layout LyX-Code
+
 #include <opie2/opimaccessfactory.h>

+OPimAccessFactory<OPimContactAccess>::defaultAccess(
+\newline 
+OPimGlobal::CONTACTLIST,

 If everything works as expected, you will receive a pointer to the contact
  access-class which has to be used for accessing the database.

 How to Access PIM-Data: Detailed View
 \layout Standard
 
 As shown in the previous chapter, all we need to access the PIM-Database
  is to request an access-object from the OPimAccessFactory and to use it.
  We will now introduce some special features of this factory (see section
  
 \begin_inset LatexCommand \ref{sec:Advanced-Factory-Features}
 
 \end_inset 
 
 ), followed by some very important features like searching and sorting in
  section 
 \begin_inset LatexCommand \ref{sec:Special-Features:-Searching}

 .
  If you are interested in accessing data without take care about their types,
  section 
 \begin_inset LatexCommand \ref{sec:Generic-Access:-OPimBase}
 
 \end_inset

  loading in section 
 \begin_inset LatexCommand \ref{sec:Internal-Signal-Handling:}

 In most cases it is not sufficient to receive just a list of all information
  in a database.
  It is essential to get a subset of the information available and to be
  able to sort it.
  For this kind of exercise we provide some special operations which provide
  searching and sorting in an incremental manner

  Before we will take a close look into sorting, we will start with searching.
  There exist two different ways of searching:

 Search a complete database for a special regular expression, using

  This search type returns all records which contains the given regular expressio
 n 
 \emph on

 \emph default 
  in the dataset.
  This search type is used for example by the opie search tool (OSearch)
  (see

 Searching with Query By Example
 \layout Standard
 
 The query by example search style is working is using a data object (for
  instance an OPimContact) to store the search query.
  For instance, if you want to request all entries which contains the last
  name 
 \begin_inset Quotes gld
 \end_inset 
 
 Eilers
 \begin_inset Quotes grd
 \end_inset 
 
  and the home zip number should start with 
 \begin_inset Quotes gld
 \end_inset 
 
 3
 \begin_inset Quotes grd
 \end_inset 
 
  you have to do the following:
 \layout LyX-Code
 
 OPimContact searchQuery;
 \layout LyX-Code
 
-searchQuery.setLastName( 
-\begin_inset Quotes eld
-\end_inset 
-
-Eilers
-\begin_inset Quotes erd

- );
+searchQuery.setLastName( "Eilers" );
 \layout LyX-Code
 
-searchQuery.setHomeZip( 
-\begin_inset Quotes eld
-\end_inset 
-
-3*
-\begin_inset Quotes srd
-\end_inset 
-
- );
+searchQuery.setHomeZip( "3*" );
 \layout Standard
 
 We use an usual 
 \begin_inset Quotes gld
 \end_inset 
 
 OPimContact
 \begin_inset Quotes grd
 \end_inset 
 
  and fill into two fields the query information.
  All filled fields are taken for the search operation (using an 
 \begin_inset Quotes gld
 \end_inset 
 
 AND
 \begin_inset Quotes grd
 \end_inset 
 
  operation), the unused ones are simply ignored.
  As we just want to search for entries which zip number starts with a 
 \begin_inset Quotes gld
 \end_inset 
 
 3
 \begin_inset Quotes grd
 \end_inset 
 
  we use the Wildcard 
 \begin_inset Quotes gld
 \end_inset 
 
 *
 \begin_inset Quotes grd
 \end_inset 
 
  as we would do to find files in a filesystem.
 \layout Standard
 
 The next step is to put this query into the operation which is defined like
  this:
 \layout LyX-Code
 
-List queryByExample (const T& query, int querySettings, const QDateTime&
- startperiod=QDateTime())
+OPimRecordList<T> queryByExample (const T& query,

 The first parameter 
 \begin_inset Quotes gld
 \end_inset

  should used to set our query, but we have to set the parameter 
 \begin_inset Quotes gld
 \end_inset 
 
 querySettings
 \begin_inset Quotes grd
 \end_inset 
 
  to configure the search properly.
  This settings are defined by the enumeration

  The meaning of all settings will be discussed later.
  For the first turn we will just concentrate on the things we need in this
  case.

 It should be clear at this stage, that this query is very powerful and -
  depending to the querySettings - could be very complicated to implement.
  Thus, not all backends do support all features defined by querySettings

 At this time, just the contact database for XML and VCard is supporting
  all queries and combination of them.
  All others just support subsets.
 \end_inset 
 
 .
  To check which settings are supported and to be able to react dynamically
  on missing features (for instance to disable some search features in the
  application) we provide the following operations:
 \layout LyX-Code
 
 bool hasQuerySettings( uint querySettings );
 \layout LyX-Code
 
 uint querySettings();
 \layout Standard
 
 The first operation 
 \begin_inset Quotes gld
 \end_inset 
 
 hasQuerySettings()
 \begin_inset Quotes grd
 \end_inset 
 
  may be used to ask whether the database can handle the given query settings.
