Macro Definition Documentation

◆ ML_PERSISTENCE_VERSION

#define ML_PERSISTENCE_VERSION (   v)    ML_SET_ADDSTATE_VERSION(v)

Nicer name for ML_SET_ADDSTATE_VERSION.

Definition at line 37 of file mlBase.h.

◆ ML_SET_ADDSTATE_VERSION

#define ML_SET_ADDSTATE_VERSION (   v)    static int getAddStateVersion(void) { return v; };

Class representing general ML objects that support import/export via strings (setPersistentState() and getPersistentState()), arbitrary tree structures (using addStateToTree() and readStateFromTree()) or a data stream (using writeTo() and readFrom()).

Macro to add the static function getAddStateVersion(void) to the implementation.

Function Documentation

◆ mlbase_cast() [1/2]

template<typename ToTypePtr >
ToTypePtr mlbase_cast ( const ml::Base from)
inline

Overload of the above template function, which makes conversion of const-pointers possible.

Definition at line 231 of file mlBase.h.

◆ mlbase_cast() [2/2]

template<typename ToTypePtr >
ToTypePtr mlbase_cast ( ml::Base from)
inline

Template function to allow type-safe casting of a base object to a derived object.

Template function to allow type-safe casting of a base object to a derived object. The function takes a from base object and returns a pointer to the desired object if the from pointer is derived from that ToTypePtr type. Otherwise a NULL pointer is returned. If NULL is passed to the function, NULL is returned. This function should be preferred to the ML_BASE_IS_A macro.

Example 1:

if (mlbase_cast<GVRVolume*>(someBaseObject)) {
GVRVolume* volume = static_cast<GVRVolume*>(someBaseObject);
...
} else if (mlbase_cast<OtherType*>(someBaseObject)) {
...
}

Example 2:

GVRVolume* volume = mlbase_cast<GVRVolume*>(someBaseObject);
if (volume) {
...
}
