installPackage

public Package installPackage(java.io.File pkg,
                              boolean force,
                              UserInteractionStrategy interact)
                       throws PackageException

Install a package from a file.

Parameters:

pkg - The package file (typically a *.xar or *.xaw file).

force - If false, an error is thrown if the package already exists. If true, the package is first deleted from the repository if it already exists.

interact - How the repository interacts with the user.

Returns:

The freshly installed package.

Throws:

PackageException - If any error occurs.

installPackage

public Package installPackage(java.net.URI pkg,
                              boolean force,
                              UserInteractionStrategy interact)
                       throws PackageException

Install a package from a URI location.

Parameters:

pkg - The package file (typically a *.xar or *.xaw file).

force - If false, an error is thrown if the package already exists. If true, the package is first deleted from the repository if it already exists.

interact - How the repository interacts with the user.

Returns:

The freshly installed package.

Throws:

PackageException - If any error occurs.

removePackage

public boolean removePackage(java.lang.String pkg,
                             boolean force,
                             UserInteractionStrategy interact)
                      throws PackageException

Remove a package from the repository, by name. If a package with that name does not exist, or if there are several versions installed, this is an error (except if the package does not exist and force is true, then simply returns false).

Parameters:

pkg - The package name.

force - To silently ignore a non existing package (simply returns false in that case).

interact - How the repository interacts with the user.

Returns:

True if the package has been successfully removed, false if not (false is returned when the user canceled removing interactively, or if the package does not exist and force is true).

Throws:

PackageException - If any error occurs during removal.

resolve

public javax.xml.transform.Source resolve(java.lang.String href,
                                          URISpace space)
                                   throws PackageException

Resolve a Saxon-specific stuff in this repository, in the specified space, return a File. TODO: FIXME: To handle empty wrappers, just forget about the generated files and so on. Just return a StreamSource over a StringReader over a generated string with the empty stylesheet or query module. That small enough to be all dealt in memory, without filesystem access. Even better! And no need for install step! TODO: Regarding versionning, see comments of Repository.resolve(String,URISpace) (AKA we don't always want the latest version).

Throws:

PackageException

getModuleURIResolver

public net.sf.saxon.lib.ModuleURIResolver getModuleURIResolver()
                                                        throws PackageException

Throws:

PackageException

getURIResolver

public javax.xml.transform.URIResolver getURIResolver(URISpace space)
                                               throws PackageException

Throws:

PackageException

registerExtensionFunctions

public void registerExtensionFunctions(net.sf.saxon.Configuration config)
                                throws PackageException

TODO: Regarding versionning, see comments of Repository.resolve(String,URISpace) (AKA we don't always want the latest version).

Throws:

PackageException
