Abstract

A method of calling a method in a virtual machine environment is provided. The method includes reading a command of a first method; storing an address of the command code in predetermined memory space if the command is a command that calls a second method; changing an address of previously-compiled code of the second method and writing the address in the stored address; and directly branching to the address of newly-compiled code of the second method and calling the second method if the first method is performed.

Description

[0001] This application is based on and claims priority from Korean Patent Application No. 10-2006-0016216 filed with the Korean Intellectual Property Office on February 20, 2006, which is hereby incorporated by reference in its entirety. technical field [0002] The methods and devices according to the present invention involve invoking methods in a virtual machine environment. More specifically, the present invention relates to an improved method of invoking a method using a table comprising a plurality of slots in which the address of the method is written, and a system comprising a virtual machine processing the method. Background technique [0003] Since applications are hardware dependent, different versions of the same application must be designed for each application platform. In order to develop platform-independent applications, virtual machines that abstract hardware platforms have been developed. A representative virtual machine is the Java virtual machine. [...
