jclass

Arguments: name-class-ref

If the argument is a string or symbol, this function returns a reference to the Java class with that name. If the class lookup triggers a Java error, a Lisp error is signaled. When caching is enabled, a new class reference is added to a local cache hashtable. If the argument is a class reference, it is returned with no further processing.

The strings "int", "short", ... are used to denote the classes that represent primitive, non-reference, values in Java.

Strings of the form "[class-or-type" are used to denote classes that represent array types.

All other classes must be specified with a fully qualified class name.

There is also a compiler macro associated with this function. It allows compile-time collection of Java class names and method signatures. This information is used to generate a file of class and method definitions that may be loaded to initialize an application, and avoid the class and method lookup overhead in the body of the application (see jlookup).
