Method Detail

close

void close()
           throws IOException

closes this archive and releases all resources

Throws:

IOException

entries

Enumeration<String> entries()

Returns an enumeration of the module file entries. All elements in the enumeration are of type String. Each String represents a file name relative to the root of the module.

Returns:

an enumeration of the archive file entries.

entries

Enumeration<String> entries(String prefix)

Returns an enumeration of the module file entries with the specified prefix. All elements in the enumeration are of type String. Each String represents a file name relative to the root of the module.

Parameters:

prefix - the prefix of entries to be included

Returns:

an enumeration of the archive file entries.

getDirectories

Collection<String> getDirectories()
                                  throws IOException

Returns the enumeration of first level directories in this archive

Returns:

enumeration of directories under the root of this archive

Throws:

IOException

isDirectory

boolean isDirectory(String name)

Returns true if the entry is a directory or a plain file

Parameters:

name - name is one of the entries returned by entries()

Returns:

true if the entry denoted by the passed name is a directory

getManifest

Manifest getManifest()
                     throws IOException

Returns the manifest information for this archive

Returns:

the manifest info

Throws:

IOException

getURI

URI getURI()

Returns the path used to create or open the underlying archive

TODO: abstraction breakage: Several callers, most notably DeploymentContext.getSourceDir() implementation, assumes that this URI is an URL, and in fact file URL.

If this needs to be URL, use of URI is misleading. And furthermore, if its needs to be a file URL, this should be File.

Returns:

the path for this archive.

getArchiveSize

long getArchiveSize()
                    throws SecurityException

Returns the size of the archive.

Returns:

long indicating the size of the archive

Throws:

SecurityException

getName

String getName()

Returns the name of the archive.

Implementations should not return null.

Returns:

the name of the archive
