Re: [jdt-core-dev] Creating an IClassFileReader
|
Actually, it doesn't quite handle internal classfiles. Will add instead the
following:
public static IClassFileReader
createDefaultClassFileReader(IClassFile classfile, int decodingFlag){
IPath filePath = classfile.getPath();
IPackageFragmentRoot root = (IPackageFragmentRoot)
classfile.getAncestor(IJavaElement.PACKAGE_FRAGMENT_ROOT);
if (root != null){
try {
IPath rootPath = root.getPath();
if (root instanceof JarPackageFragmentRoot) {
String archiveName =
((JarPackageFragmentRoot)root).getJar().getName();
String entryName = classfile.getParent
().getElementName();
entryName = entryName.replace('.', '/');
if (entryName.equals("")) { //$NON-NLS-1$
entryName += classfile.getElementName
();
} else {
entryName += '/' +
classfile.getElementName();
}
return
createDefaultClassFileReader(archiveName, entryName, decodingFlag);
} else {
return
createDefaultClassFileReader(classfile.getCorrespondingResource
().getLocation().toOSString(), decodingFlag);
}
} catch(CoreException e){
}
}
return null;
}

You're right, this should do the trick. I'll add it onto the ToolFactory.
/**
* Helper method to create a classfile reader onto a classfile Java
element.
* Create a default classfile reader, able to expose the internal
representation of a given classfile
* according to the decoding flag used to initialize the reader.
* Answer null if the file named fileName doesn't represent a valid
.class file.
*
* The decoding flags are described in IClassFileReader.
*
* @param classfile the classfile element to introspect
* @param decodingFlag the flag used to decode the class file reader.
* @return a default classfile reader
*
* @see IClassFileReader
*/
public static IClassFileReader
createDefaultClassFileReader(IClassFile classfile, int decodingFlag){
IPath filePath = classfile.getPath();
IPackageFragmentRoot root = (IPackageFragmentRoot)
classfile.getAncestor(IJavaElement.PACKAGE_FRAGMENT_ROOT);
if (root != null) {
try {
IResource rootRsc = root.getCorrespondingResource
();
IPath rootPath = root.getPath();
if ((rootRsc == null || rootRsc.getType() ==
IResource.FILE)
&&
Util.isArchiveFileName(rootPath.lastSegment())) {
String archiveName = filePath.toString();
String entryName = classfile.getParent
().getElementName();
entryName = entryName.replace('.', '/');
if (entryName.equals("")) { //$NON-NLS-1$
entryName += classfile.getElementName
();
} else {
entryName += '/' +
classfile.getElementName();
}
return
createDefaultClassFileReader(archiveName, entryName, decodingFlag);
}
} catch(JavaModelException e){
return null;
}
}
return createDefaultClassFileReader(filePath.toString(),
decodingFlag);
}

Please respond to
jdt-core-dev
In the case of a jar, the current implementation returns the file path of
the enclosing jar for classfile.getPath().
