Classes:

• JavaFactory: JavaFactory provides generators for Java constructs. Once Java constructs have been connected into a complete class definition, the class can be generated from them. The generated class is created as a byte-code array that can then be loaded by a class loader or, in our case, the class utilities wrapper around our special class loader. Each method shows the equivalent Java in the line starting "Java:" in the header comment. Items in the java code that begin with # refer to parameters used in constructing the object. So, for example, newReturnStatement takes a parameter named value; its Java code ...
• ClassBuilder: ClassBuilder is used to construct a java class's byte array representation. Limitations: No checking for language use violations such as invalid modifiers or duplicate field names. All classes must have a superclass; java.lang.Object must be supplied if there is no superclass. When a class is first created, it has: a superclass modifiers a name a package no superinterfaces, methods, fields, or constructors an empty static initializer MethodBuilder implementations are required to get code out of the constructs within their bodies in some manner. Most typically, they may have a stream to which the ...
• MethodBuilder: MethodBuilder is used to generate the code for a method. The code for a method is built in a way that corresponds to the layout of the stack machine that is the Java Virtual Machine. Values are pushed on the stack, moved about on the stack and then popped off the stack by operations such as method calls. An understanding of hoe the JVM operates is useful before using this class. All the method descriptions below are generating bytecode to achieved the desired behaviour when the generated class is loaded. None of this class's methods calls actually invoke methods or create objects described by the ...
• LocalField: A field within the generated class.
