Class JavaElement

java.lang.Object

aQute.bnd.differ.JavaElement

class JavaElement
extends java.lang.Object

An element that compares the access field in a binary compatible way. This element is used for classes, methods, constructors, and fields. For that reason we also included the only method that uses this class as a static method.

Constructor Detail

JavaElement

JavaElement(Analyzer analyzer)
     throws java.lang.Exception

Create an element for the API. We take the exported packages and traverse those for their classes. If there is no manifest or it does not describe a bundle we assume the whole contents is exported.

Throws:

java.lang.Exception

Method Detail

getAPI

static Element getAPI(Analyzer analyzer)
               throws java.lang.Exception

Throws:

java.lang.Exception

getLocalAPI

private Element getLocalAPI()
                     throws java.lang.Exception

Throws:

java.lang.Exception

classElement

Element classElement(Clazz clazz)
              throws java.lang.Exception

Calculate the class element. This requires parsing the class file and finding all the methods that were added etc. The parsing will take super interfaces and super classes into account. For this reason it maintains a queue of classes/interfaces to parse.

Throws:

java.lang.Exception

toString

private java.lang.String toString(Descriptors.TypeRef[] prototype)

getReturn

private Element getReturn(Descriptors.TypeRef type)

access

private static void access(java.util.Collection<Element> children,
                           int access,
                           boolean deprecated,
                           boolean provider)
