XPCOM glue classes 编辑

These "glue" classes are provided to make it easier to use XPCOM from C++ code. When these classes are used by a component, you may need to link the component against the XPCOM glue library.

NS_OVERRIDE

NS_OVERRIDE is a macro which allows C++ code in Mozilla to specify that a method is intended to override a base class method. If there is no base class method with the same signature, a compiler with static-checking enabled will fail to compile.

nsACString

The nsACString abstract class represents a character string composed of single-byte storage units. This class is typically used to represent ASCII or UTF-8 character arrays.

nsAutoRef

nsAutoRef<t> is a template class implementing an object that holds a handle to a resource that must be released, typically on destruction of the object.</t>

nsAutoRefTraits

nsAutoRefTraits<t> is a template class describing traits of resources held by objects of class nsAutoRef<T> and/or nsCountedRef<T>.</t>

nsMemory

The nsMemory class provides static helper routines to manage memory. These routines allow easy access to XPCOM's global nsIMemory implementation without having to go through the service manager to get it.

nsRefPtr

RefPtr (formerly known as nsRefPtr, see bug 1207245) is a general class to implement reference counting pointers for objects. It is similar to nsCOMPtr, but does not require that the type be an XPCOM interface.  Like with nsCOMPtr, it is the responsibility of the object itself to implement reference counting. This is done using the functions AddRef() and Release(), which respectively modify a variable of type nsAutoRefCnt, which basically is a wrapper around a count of the number of references refering to the class.
