A default allocator implementation based on global new and delete.
This implementation realizes the singleton pattern. An instance of the default allocator can be obtained through the static inline method mi::base::Default_allocator::get_instance().

Declares the interface ID (IID) of this interface.

Own type.

Compares the interface ID iid against the interface ID of this interface and of its ancestors.
true if iid == IID() or is equal to one of the interface IDs of its ancestors, and false otherwise.

inlinevirtualinherited |
Returns the interface ID of the most derived interface.
Implements mi::base::IInterface.

Acquires a mutable interface.
If this interface is derived from or is the interface with the passed interface_id, then return a non-NULL mi::base::IInterface* that can be casted via static_cast to an interface pointer of the interface type corresponding to the passed interface_id. Otherwise return NULL.
In the case of a non-NULL return value, the caller receives ownership of the new interface pointer, whose reference count has been retained once. The caller must release the returned interface pointer at the end to prevent a memory leak.
Implements mi::base::IInterface.

Acquires a const interface.
If this interface is derived from or is the interface with the passed interface_id, then return a non-NULL const mi::base::IInterface* that can be casted via static_cast to an interface pointer of the interface type corresponding to the passed interface_id. Otherwise return NULL.
In the case of a non-NULL return value, the caller receives ownership of the new interface pointer, whose reference count has been retained once. The caller must release the returned interface pointer at the end to prevent a memory leak.
