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

yield

protected java.io.InputStream yield(java.util.zip.ZipEntry zipEntry,
                                    java.io.InputStream inputStream)
                             throws java.io.IOException

Overrides:

yield in class ArchiveURLConnection

Throws:

java.io.IOException

yield

protected java.io.OutputStream yield(java.util.zip.ZipEntry zipEntry,
                                     java.io.OutputStream outputStream)
                              throws java.io.IOException

Overrides:

yield in class ArchiveURLConnection

Throws:

java.io.IOException

getAttributes

public java.util.Map<java.lang.String,?> getAttributes()

setAttributes

public void setAttributes(java.util.Map<java.lang.String,?> attributes)
                   throws java.io.IOException

Throws:

java.io.IOException
