Detailed Description

Loads plugins from a shared library.

This class is used to handle dynamic loading of module/classes. It is rarely used directly but instead is inherited for a particular purpose such as managing class specific map projections or camera models. The class is derived from a PVL which aides in the selection of the shared library and plugin routine to load. For example, assume the file my.plugin contained:

OBJECT=SINUSOIDAL
LIBRARY=libisis3.so
END_OBJECT
OBJECT=SIMPLECYLINDRICAL
LIBRARY=libisis3.so
END_OBJECT
Isis::Projection * SimpleCylindricalPlugin(Isis::Pvl &lab, bool allowDefaults)
This is the function that is called in order to instantiate a SimpleCylindrical object.
Definition SimpleCylindrical.cpp:275
Isis::TProjection * SinusoidalPlugin(Isis::Pvl &lab, bool allowDefaults)
This is the function that is called in order to instantiate a Sinusoidal object.
Definition Sinusoidal.cpp:292

The desired routine can be selected in code as follows:

p.Read("my.plugin");
string proj;
cin >> proj; // Enter either SINUSOIDAL or SIMPLECYLINDRICAL
p.Find(proj);
void *ptr = p.GetPlugin();
Loads plugins from a shared library.
Definition Plugin.h:55
QFunctionPointer GetPlugin(const QString &group)
This method returns a void pointer to a C function (i.e., the plugin) It does this by looking in itse...
Definition Plugin.cpp:39

Obtaining plugins can be difficult to understand. It is suggested you look at ProjectionFactory to get a better understanding of how they are used.

◆ addKeyword() [1/2]

void Isis::PvlContainer::addKeyword ( const PvlKeyword & keyword,

Add a keyword to the container.

Add a keyword to the PvlContainer object.

Parameters
keywordThe PvlKeyword object to append.
modeUsing the InsertMode value of Append.
keyThe PvlKeyword object to add.
modeThe enum InsertMode has two possible values, Append or Replace. Use Append if you just want to add it to the end, Replace if you want to replace it.

◆ addKeyword() [2/2]

PvlContainer::PvlKeywordIterator Isis::PvlContainer::addKeyword ( const PvlKeyword & keyword,
PvlKeywordIterator pos )
inherited

Insert a keyword at the specified iterator position.

This method provides the capability to insert a keyword at the specified iterator position. The process follows the description of the STL vector definition along with all the caveats (e.g., invalidation of iterators upon insert operations).

This method will not perform any checks for the existance of the keyword. This could lead to multiple instances of the same keyword in the same container. It is up to the caller to manage this issue.

Parameters
keyKeyword to insert
posIterator position where to insert the new keyword
Returns
PvlContainer::PvlKeywordIterator Returns the position of the inserted keyword per the STL vector documentation.

Parameters
groupThe group name.
Returns
A void pointer to a C function (i.e., the plugin)
