InputJarArchive

public InputJarArchive()

Method Detail

getArchiveSize

public long getArchiveSize()
                    throws java.lang.NullPointerException,
                           java.lang.SecurityException

Get the size of the archive

Specified by:

getArchiveSize in interface Archive

Returns:

tje the size of this archive or -1 on error

Throws:

java.lang.NullPointerException

java.lang.SecurityException

addEntry

public java.io.OutputStream addEntry(java.lang.String name)
                              throws java.io.IOException

Parameters:

name - the entry name

Returns:

an @see java.io.OutputStream for a new entry in this current abstract archive.

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

close the abstract archive

Specified by:

close in interface Archive

Throws:

java.io.IOException

getDirectories

public java.util.Collection<java.lang.String> getDirectories()
                                                      throws java.io.IOException

Returns the collection of first level directories in this archive.

Avoid having to fetch all the entries if we can avoid it. The only time we must do that is if size() is invoked on the collection. Use the CollectionWrappedEnumeration for this optimization which will create a full in-memory list of the entries only if and when needed to satisfy the size() method.

Specified by:

getDirectories in interface Archive

Returns:

collection of directories under the root of this archive

Throws:

java.io.IOException

create

public void create(java.net.URI uri)

Parameters:

uri - the path to create the archive

java.io.IOException

entries

public java.util.Enumeration<java.lang.String> entries()

Specified by:
