Abstract

A JAVA-based virtual machine that supports input method editor (IME) functionality in three contexts: (1) using JAVA-based IMEs with a JAVA virtual machine; (2) writing JAVA-based IMEs; and (3) integrating a JAVA virtual machine to system IMEs. The virtual machine includes a windows manager, an input method manager, one or more IMEs and/or keyboard drivers (KBDs), and a component. The virtual machine may also include an IME bridge for integrating the virtual machine with a system IME. The windows manager serves as a gateway between the operating system and the virtual machine. The input method manager (IMM) serves as a router between the windows manager and a plurality of IMEs and keyboards driver (KBDs). The IME includes a look-up table of composed characters that are indexed by Unicode keyboard commands. The component typically renders a user interface that allows the user to manipulate the composed characters returned by the IME. The functionality of the IME and the component may vary from platform to platform, and from user to user. The virtual machine can implement a predefined set of interfaces that allow the IME and the component to communicate with each other and with the windows manager and the input method manager. These predefined interfaces allow users to modify the functionality of the IME and component and integrate these modified elements with the virtual machine.
