Reverse engineering is a processus to rebuild UML model from language implementation. In Java, some information can be retrieved easily by parsing syntaxly Java source code or by decoding class binary file structure, such as:

• Java type class/interface
• Inheritance
• Attributes

Others need a complex code semantic analysis, such as:

• Getter/setter methods
• Cardinality of association
• Element type in a collection
• Inverse association resolution
• Qualified association

Precisely, it is necessary to analyze method implementation content to capture them. EclipseUML Enterprise Edition provides a very powerful reverse engineering engine to meet these requirements based on the byte-code analysis. Additionally, it provides following features:

• Model attribute detection
• Alive dependance detection between classes and packages
• Customizable dependance definition

EclipseUML Enterprise Edition uses the reverse engineering engine in two ways:

• UML model reverse engineering
• Dependancy detection
