Saving the ICS stream to memory

[DrJohannessen]

This is kind of a noob question, but as far as i understand the library if i use the load functioin to load a stream, then it puts the stream into a calendar object, and then i can iterate over it. is there any possibility of parsing it while its is streaming, so that i dont have to safe the whole calender, but can just throw away the parts that i dont need?
