Method Detail

emulateArchiveScheme

protected boolean emulateArchiveScheme()
Description copied from class: ArchiveURLConnection

Returns whether the implementation will handle all the archive accessors directly. For example, whether
  archive:jar:file:///c:/temp/example.zip!/org/example/nested.zip!/org/example/deeply-nested.html
will be handled as if it were specified as
  archive:file:///c:/temp/example.zip!/org/example/nested.zip!/org/example/deeply-nested.html
Override this only if you are reusing the logic of retrieving an input stream into an archive and hence are likely to be overriding createInputStream, which is the point of delegation to the nested URL for recursive stream creation.

Overrides:
emulateArchiveScheme in class ArchiveURLConnection
Returns:
whether the implementation will handle all the archive accessors directly.

useZipFile

protected boolean useZipFile()
Description copied from class: ArchiveURLConnection
Returns whether to handle the special case of a nested URL with file: schema using a ZipFile. This gives more efficient direct access to the root entry, e.g.,
  archive:file:///c:/temp/example.zip!/org/example/nested.html

Overrides:
useZipFile in class ArchiveURLConnection
Returns:
whether to handle the special case of a nested URL with file: schema using a ZipFile.

createInputStream

protected java.io.InputStream createInputStream(java.lang.String nestedURL)
                                         throws java.io.IOException
Description copied from class: ArchiveURLConnection
Creates an input stream for the nested URL by calling opening a stream on it.

Overrides:
createInputStream in class ArchiveURLConnection
Parameters:
nestedURL - the nested URL for which a stream is required.
Returns:
the open stream of the nested URL.
Throws:
java.io.IOException

createOutputStream

protected java.io.OutputStream createOutputStream(java.lang.String nestedURL)
                                           throws java.io.IOException
Description copied from class: ArchiveURLConnection
Creates an output stream for the nested URL by calling opening a stream on it.

Overrides:
createOutputStream in class ArchiveURLConnection
Parameters:
nestedURL - the nested URL for which a stream is required.
Returns:
the open stream of the nested URL.
Throws:
java.io.IOException
