Class NestedDirBundleFile

java.lang.Object

org.eclipse.osgi.baseadaptor.bundlefile.BundleFile

org.eclipse.osgi.baseadaptor.bundlefile.NestedDirBundleFile

public class NestedDirBundleFile
extends BundleFile

A NestedDirBundleFile uses another BundleFile as its source but accesses all of its resources relative to a nested directory within the other BundleFile object. This is used to support zipped bundles that use a Bundle-ClassPath with an nested directory specified.

For Example:

 Bundle-ClassPath: nested.jar,nesteddir/

getEntry

public BundleEntry getEntry(String path)

Description copied from class: BundleFile

Parameters:

path - path of the entry to locate in the bundle

Returns:

BundleEntry object or null if the file name does not exist in the bundle

containsDir

public boolean containsDir(String dir)

Description copied from class: BundleFile

Determines if any BundleEntries exist in the given directory path.

Specified by:

containsDir in class BundleFile

Parameters:

dir - The directory path to check existence of.

Returns:

true if the BundleFile contains entries under the given directory path; false otherwise.

getEntryPaths

public Enumeration<String> getEntryPaths(String path)

Description copied from class: BundleFile

Allows to access the entries of the bundle. Since the bundle content is usually a jar, this allows to access the jar contents. GetEntryPaths allows to enumerate the content of "path". If path is a directory, it is equivalent to listing the directory contents. The returned names are either files or directories themselves. If a returned name is a directory, it finishes with a slash. If a returned name is a file, it does not finish with a slash.

Specified by:

getEntryPaths in class BundleFile

Parameters:

path - path of the entry to locate in the bundle

Returns:

an Enumeration of Strings that indicate the paths found or null if the path does not exist.

getFile

public File getFile(String entry,
           boolean nativeCode)

Description copied from class: BundleFile

Returns a File for the bundle entry specified by the path. If required the content of the bundle entry is extracted into a file on the file system.

Specified by:

getFile in class BundleFile

Parameters:

entry - The path to the entry to locate a File for.

nativeCode - true if the path is native code.

Returns:

A File object to access the contents of the bundle entry.
