Do COM keep track of all the object references(Accounting)?
Answer Posted / vidhya
Component uses reference count for memory
management.whenever a client gets an interface,reference
count get incremented. When client finishes using interface
reference count get decremented. If the reference count
goes to 0, component deletes itself from memory. When
client uses existing interface to create another reference
client has to increment reference count by calling "AddRef"
and release when client finshes using interface.
