ensure
Description:
[ Version ( since = "2.34" ) ]
public void ensure ()
public void ensure ()
Ensures that the indicated type
has been registered with the type system, and its _class_init
method has been run.
In theory, simply calling the type's _get_type
method (or using the corresponding macro) is supposed take care of this. However,
_get_type
methods are often marked g_gnuc_const for performance reasons, even though this is
technically incorrect (since g_gnuc_const requires that the function not have side effects, which
_get_type
methods do on the first call). As a result, if you write a bare call to a _get_type
macro, it may get optimized
out by the compiler. Using ensure guarantees that the type's _get_type
method is called.
