Today, I was having a trouble shooting about Calibration LCD. I creates a map to handle an interface between the physical x and y position on the LCD and virtual x and y position.
Customized Binary Search Tree is created and it stores a raw data associated with x and y position. The computation time is a constant time, the search time is log(n) if there is no data in the look up table (Hashtable), otherwise a constant time to search.
I joined OpenJPA open source project. now I am reading the Java Persistence 2.0 Early version of specification. It might help our DataMinder product improve data utilization.
so...tired.
