Method Detail

openArchive

void openArchive(String archiveName)
                 throws IOException,
                        AutomationException

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

archiveName - The archiveName (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

createArchive

void createArchive(String archiveName)
                   throws IOException,
                          AutomationException

Creates a new archive.

Description

Creates a new zip archive with the specified file name. The file name must include the zip extension (*.zip).

If a zip archive with the specified file name already exists it will automatically be replaced with a new empty zip archive and the contents of the previous zip archive will be lost.

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

archiveName - The archiveName (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

closeArchive

void closeArchive()
                  throws IOException,
                         AutomationException

             throws IOException,
                    AutomationException

Compresses a file and adds it to the archive.

Description

Compresses and adds the specified file to the zip archive. Ensure the zip archive is open before using the AddFile method by either using the CreateArchive (if you just created an archive) or OpenArchive (if you are using a previously created archive) methods.
