The sources read by theJava code reverse are the ones having the extension specified in the generation settings. The tree formed by the sub-directories producean equivalent tree of sub-packages, on whose the needed class view and deployment view are made to support the classes and artifacts.When a type is referenced but not defined in the reverse files, a class having the same name is defined under an additional package namedunknown.Obviously the Java code reverse tries to produce the definitions made in BOUML at the artifact / class / operation / relation / attributelevels. When it is possible it creates a relation rather than an attribute.A artifact is created for each type definition, then a future Java code generation may not produce a list of files similar to the reversed ones.The Java code reverse works in two steps, during the first step it scans all the files to establish the list of defined types, then the secondstep may reverse the files.When the Java code reversehas a problem, for instance on a syntax error, it produces a warning in the trace window. The trace window is automatically openeBOUML, it may also be manually opened through the Tools menu.When the reverse is done, the number of reversed classes, operations, attributes and relations is written, for instance in case I reverse afull JDK Java distribution :See also Java catalog.Previous : Java generatorNext : Java catalog
