#define SCF_CONSTRUCT_EMBEDDED_IBASE ( Interface   ) 

Value:

Interface.scfParent = this;                                             \
  csRefTrackerAccess::AddAlias (&Interface, this);
The SCF_CONSTRUCT_EMBEDDED_IBASE macro should be invoked inside the constructor of a class that has an embedded interface (not inside the constructor of the embedded interface).

The macro will initialize the pointer to the parent object (to the object this one is embedded into). The argument to this macro is the name of the parent's instance variable by which the embedded object is known (typically something like `scfiFooBar').

Definition at line 145 of file scf.h.

#define SCF_CONSTRUCT_IBASE ( Parent   ) 

Value:

csRefTrackerAccess::TrackConstruction (this);                           \
  csRefTrackerAccess::SetDescription (this, CS_TYPENAME(*this));        \

  scfParent = Parent; if (scfParent) scfParent->IncRef();               \
  SCF_INIT_TRACKER_ALIASES
The SCF_CONSTRUCT_IBASE macro should be invoked inside the constructor of a class (not inside an embedded interface).

Normally each constructor should accept an iBase* parameter (that is passed by scfCreateInstance function) which should be passed to this macro. The macro will zero the reference count and initialize the pointer to the parent object. If the object is unparented (a common case), it is okay to use null as the argument to this macro.

#define SCF_DECLARE_IBASE_EXT ( ParentClass   ) 

Value:

typedef ParentClass __scf_superclass;                                   \
  virtual void IncRef ();                                               \

  virtual void RemoveRefOwner (void** ref_owner);                       \
  virtual void *QueryInterface (scfInterfaceID iInterfaceID, int iVersion)
The following macro is used in "expansion SCF classes".

An expansion class is a class that extends the functionality of another SCF class. For example, suppose a class TheWolf that implements the iWolf interface. Separately it is a useful class per se, but if you want to implement an additional class TheDog that is a subclass of TheWolf and which implements an additional interface iDog in theory you should just override the QueryInterface method and return the corresponding pointer when asked. The following macro makes such overrides simpler to write.

{ Class ## _scfUnitInitialize(SCF); }
The SCF_IMPLEMENT_FACTORY_INIT macro defines initialization code for a plugin module.

This function should set the plugin-global iSCF::SCF variable, and otherwise initialize the plugin module. Although a version of this function will be created for each SCF factory exported by the plugin, SCF will call one, and only one, to perform the plugin initialization. The choice of which function will be invoked to initialize the plugin is an SCF implementation detail. You should not attempt to predict which class_scfInitialize() function will be used, nor should use try to sway SCF's choice. Implementation note: There are some rare instances where a particularly picky (and probably buggy) compiler does not allow C++ expressions within a function declared `extern "C"'. For this reason, the iSCF::SCF variable is instead initialized in the Class_scfUnitInitialize() function which is not qualified as `extern "C"'.

The SCF_IMPLEMENT_IBASE_DECREF() macro implements the DecRef() method for a class in a C++ source module.

Typically, this macro is automatically employed by the SCF_IMPLEMENT_IBASE() convenience macro.

#define SCF_IMPLEMENTS_INTERFACE_COMMON ( Interface,
Object   ) 

Value:

if (iInterfaceID == scfInterfaceTraits<Interface>::GetID() &&           \
    scfCompatibleVersion (iVersion, scfInterfaceTraits<Interface>::GetVersion())) \
  {                                                                     \
    (Object)->IncRef ();                                                \
    return static_cast<Interface*> (Object);                            \
  }
This is a common macro used in all IMPLEMENTS_XXX_INTERFACE macros.

#define SCF_INTERFACE ( Name,
Major,
Minor,
Micro   ) 

Value:

struct InterfaceTraits {                                  \
  typedef Name InterfaceType;                             \
  CS_FORCEINLINE static scfInterfaceVersion GetVersion() \
  { return SCF_CONSTRUCT_VERSION(Major, Minor, Micro); }  \
  CS_FORCEINLINE static char const * GetName() { return #Name; }  \
}
SCF_INTERFACE can be used to define an interface's version number; you should specify interface name and major, minor and micro version components.

This way:

 struct iSomething : public iBase
 {
 public:
   SCF_INTERFACE(iSomething, 0, 0, 1);
   ...
 };

Automatically register a built-in class with SCF during startup.

When SCF classes are statically linked (vs dynamic linking) they should be referenced from somewhere inside your program, otherwise the static libraries won't be linked into the static executable. This macro defines a dummy variable that registers the class during initialization and ensures that it gets linked into the program

FOR COMPATIBILITY! SCF_VERSION can be used to define an interface's version number; you should specify interface name and major, minor and micro version components.

This way:

 SCF_VERSION (iSomething, 0, 0, 1);
 struct iSomething : public iBase
   ...
 };
 
Notice that SCF_VERSION cannot be used on interfaces in namespaces

csPtr<Interface> csLoadPluginCheck ( iPluginManager mgr,
const char *  ClassID 
) [inline]

Tell plugin manager to load a plugin but first check if the plugin is not already loaded.

Interface: Desired interface type (ex. iGraphics2D, iVFS, etc.).

Parameters:
mgr An object that implements iPluginManager.
ClassID The SCF class name (ex. crystalspace.graphics3d.software).

template<class Interface>
csPtr<Interface> csQueryPluginClass ( iPluginManager mgr,
const char *  ClassID 
) [inline]

Find a plugin by its class ID.

First the plugin with requested class identifier is found, and after this it is queried for the respective interface; if it does not implement the requested interface, 0 is returned. Interface: Desired interface type (ex. iGraphics2D, iVFS, etc.).

Parameters:
mgr An object that implements iPluginManager.
ClassID The SCF class name (ex. crystalspace.graphics3d.software).

template<class Interface>
csPtr<Interface> csQueryRegistryOrLoad ( iObjectRegistry Reg,
const char *  classID,
bool  report = true 
) [inline]

Use this macro to query the object registry, loading a plugin if needed.

If an object with a given interface exists in an object registry, get that object from the registry. If the registry query fails, try to load a plugin and get the interface from there. If that succeeds, the interface is added to the registry for future use and given a tag the same name as the requested interface. Example use:

 csRef<iDynamics> dynamic_system = csQueryRegistryOrLoad<iDynamics> (
        object_reg, "crystalspace.dynamics.ode");

Parameters:
Reg The object registry (of type iObjectRegistry).
classID The requested SCF class name (ex. "crystalspace.dynamice.ode")
report if true then we will report an error in case of error.
Todo:
This probably ought to be made more thread-safe by locking the object registry if possible.
Returns:
a reference to the requested interface if successful. Otherwise this function returns 0.

void scfInitialize ( int  argc,
const char *const   argv[] 
)

This function should be called to initialize client SCF library.

It uses the default plugin paths provided by csGetPluginPaths().

void scfInitialize ( csPathsList const *  pluginPaths,
unsigned int  verbose = SCF_VERBOSE_NONE 
)

This function should be called to initialize client SCF library.

If a number of plugin paths are provided, the directories will be scanned for plugins and their SCF-related registry data will be retrieved. The root node within the registry data document should be named "plugin", and the SCF-related information should be in a child node of the root named "scf". It is legal to call scfInitialize more than once (possibly providing a different set of directories each time).

Parameters:
pluginPaths Directories that will be scanned for plugins. If this parameter is 0, the paths returned by csGetPluginPaths() will be scanned.
verbose One or more of the SCF_VERBOSE_FOO flags combined with bitwise-or which control SCF verbosity.
Remarks:
The path list is ignored for static builds.
