ClassMap is a class that maps short names (i.e. short, lower case strings) to java classes and can instantiate them. This is useful for dynamic resolution of classes but with a small set of known defaults that have a short name. If the short name is not in the default set, this class will treat the short name as a fully qualified Java class name and load it. This class does the requisite checking--that the class exists, that it can be loaded, that it is of the appropriate type, that it can be instantiated, etc.

This hashtable is used for replacing class names in a class definition or a method body. Define a subclass of this class if a more complex mapping algorithm is needed. For example,
class MyClassMap extends ClassMap { public Object get(Object jvmClassName) { String name = toJavaName((String)jvmClassName); if (name.startsWith("java.")) return toJvmName("java2." + name.substring(5)); else return super.get(jvmClassName); } } This subclass maps java.lang.String to java2.lang.String. Note that get() receives and returns the internal representation of a class name. For example, the internal representation of java.lang.String is java/lang/String.
Note that this is a map from String to String.
