Abstract
A method of creating drive component object and realizing device drive program multiplicity on basis of category, in which the drive component class is defined and realized at first, then the component customer program creates drive object with category intellectual pointer. In present invention, the operation system selects automatically the corresponding component based on specified component kind by customer specification and realizes further a multi-mode access to drive program from application program. In present invention, certain overheads for efficiency are needed to be added only in the dynamic binding in course of drive object creating; once drive object is created, the operation system would returns the common interface realized by drive object back to the application program and application program may invoke directly the particular drive object method, it has no extra efficiency overhead and realizes a multi-mode access to drive program from application program.
