Class Hierarchy
• FJ-JAVA-BASE: Super class of every adapter class
• FJ-JAVA-CONTROL: Initializes or terminates the Java VM, or connects or
disconnects a thread to the Java VM.
• FJ-JAVA-ERROR: Class of exception object generated in the adapter class.
• Class adapter class: An adapter class (java-lang-Object) of the java.lang.Object
class is generated as a subclass of FJ-JAVA-BASE. Other adapter classes having
the same inheritance relationships as Java classes are generated. An adapter
class of the class in which a Java interface is installed inherits an interface
adapter class as well.
• Interface adapter class: The adapter class of an interface that inherits no other
interface is generated as a subclass of java-lang-Object. The adapter class of an
interface that inherits another interface is generated so that it has the same
inheritance relationship as the Java interface.
• Array adapter class: Every array adapter class is generated as a subclass of
java-lang-Object.
