CArchive::ReadObject

CObject*ReadObject(constCRuntimeClass*pClass);
throw(CFileException,CArchiveException,CMemoryException);

Return Value

A CObject pointer that must be safely cast to the correct derived class by using CObject::IsKindOf.

Parameters

pClass

A constant pointer to the CRuntimeClass structure that corresponds to the object you expect to read.

Remarks

Reads object data from the archive and constructs an object of the appropriate type.

This function is normally called by the CArchive extraction (>>) operator overloaded for a CObject pointer. ReadObject, in turn, calls the Serialize function of the archived class.

If you supply a nonzero pClass parameter, which is obtained by the RUNTIME_CLASS macro, then the function verifies the run-time class of the archived object. This assumes you have used the IMPLEMENT_SERIAL macro in the implementation of the class.

Example
