SuperWaba is a discontinued Java-like virtual machine (VM) that targets portable devices. Software developers use application programming interfaces (APIs), accessed through associated libraries (packaged as Jars) and small tools (together composing a software development kit), to create applications that can run within the VM on supported platforms. ==Architecture== The SuperWaba VM and API implement a subset of the Java programming language, which allows it to run under a standard Java VM or as a Java applet. This is in contrast to the Java Micro Edition which was designed under a different Java specification than that used by the Java Standard Edition. Classes compiled for the SuperWaba VM must be compiled for Java 2, Standard Edition 1.2 compatibility. Note that the SuperWaba VM does not conform to a particular specification. However, the SuperWaba API allows recompiling an application's classes to the Java Standard Edition. When an application is retargeted in this way, all versions of the Java Standard Edition are supported. Despite its likeness to the Java 2 standard edition specification, SuperWaba is appropriately constrained for hardware limitations typically encountered on portable devices. Especially, the SuperWaba VM has been optimized for use on devices with small screens. Compiled code runs at 1/3 to 1/2 the speed of a pure C application on a Palm platform, and on a Windows API (Win32) platform is approximately three to four times faster than a JIT-compiled Java due partly to its integer-only implementation. Additional mathematics libraries for non-integer arithmetic are provided with the SDK. The SuperWaba VM and API are both extensible. They are published under the GPL free software license. Also, licensees may buy an LGPL version, that lets them link it with proprietary software. Applications and libraries written for SuperWaba may be sold, but most appear to be available as free software from the main website. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SuperWaba」の詳細全文を読む スポンサード リンク
