OpenJava is an extensible language based on Java. The extended +features of OpenJava are specified by a meta-level program given at +compile time. For distinction, programs written in OpenJava are called +base-level programs. If no meta-level program is given, OpenJava is +identical to regular Java. + +

The meta-level program extends OpenJava through the interface +called the OpenJava MOP (Metaobject Protocol). The OpenJava compiler +consists of three stages: preprocessor, source-to-source translator +from OpenJava to Java, and the back-end Java compiler. The OpenJava +MOP is an interface to control the translator at the second stage. It +allows to specify how an extended feature of OpenJava is translated +into regular Java code. + +

An extended feature of OpenJava is supplied as an add-on software +for the compiler. The add-on software consists of not only the +meta-level program but runtime support code. The runtime support code +provides classes used by the base-level program translated into +Java. The base-level program in OpenJava is first translated into Java +by the meta-level program and is dynamically linked with the runtime +support code. + +

The meta-level program is written in Java, accurately in OpenJava +because OpenJava is a self-reflective language. It defines new +metaobjects to control source-to-source translation. The metaobjects +are the meta-level representation of the base-level program and they +perform the translation. Details of the metaobjects are specified by +the OpenJava MOP. In the following, we go through a few examples so +that we illustrate how the OpenJava MOP is used to implement language +extensions. +
