Optional aInstancePtr: objectA run time mechanism for interface discovery.
NS_OK if the interface is supported by the associated instance, NS_NOINTERFACE if it is not.
aInstancePtr must not be null.
[in] A requested interface IID
[out] A pointer to an interface pointer to receive the result.
Initialize the object implementing nsISerializable, which must have been freshly constructed via CreateInstance. All data members that can't be set to default values must have been serialized by write, and should be read from aInputStream in the same order by this method.
Serialize the object implementing nsISerializable to aOutputStream, by writing each data member that must be recovered later to reconstitute a working replica of this object, in a canonical member and byte order, to aOutputStream.
NB: a class that implements nsISerializable must also implement nsIClassInfo, in particular nsIClassInfo::GetClassID.
Generated using TypeDoc
Increases the reference count for this interface. The associated instance will not be deleted unless the reference count is returned to zero.
Returns
The resulting reference count.
