Description

Class Summary
Catalog	A `Catalog` is the list of packages (Fmris) that are available from an authority.
Fmri	An `Fmri` is an identifier for a package.
Image	An `Image` is a directory tree containing the laid-down contents of a self-consistent graph of Packages.
Image.FmriState	An `FmriState` represents the current state of an Fmri within the image.
Manifest	A `Manifest` is a list of actions within a package.
Version	A `Version` represents the version part of an IPS package FMRI.
Version.DotSequence	The `DotSequence` class represents the x.y.z parts of a Version object.

Package com.sun.pkg.client Description

Provides for client-side access to the Image Packaging System (IPS) for Java clients. The primary class for using this API is the Image class.

Usage Examples

This section contains some examples of how to use this API to accomplish some typical tasks.

Install the most recent version of a given package

The objective of this example is to install the most recent version of the "foo" package into the image rooted at "bar" in the user's home directory.

    File dir = new File(System.getProperty("user.home"), "bar");
    Image img = new Image(dir);
    String pkgs[] = {"foo"};
    img.installPackages(pkgs);

Check to see if a given package is installed

The objective of this example is to determine whether the "foo" package has been installed into the image. This example uses the Image object from the previous example.

    List list = img.getInventory(pkgs, false);
    if (list.size() > 0) {
        System.out.println("package foo is installed");
    }

Update the packages in an image

The objective of this example is to print a list of the packages that have available updates in the image and then install those updates. This example uses the Image object from the previous example.

    List list2 = img.getInventory(null, false);
    ArrayList pkgs2 = new ArrayList();
    for (Image.FmriState fs : list2) {
      if (fs.upgradable) {
        pkgs2.add(fs.fmri);
        Fmri p = img.getCatalog().getMatchingFMRI(fs.fmri.getName());
        System.out.println("available update: " + p.toString());
      }
    }
    img.installPackages(pkgs2);

Logging

The pkg Java API generates log information to the com.sun.pkg.client Logger. The following code can be used to manipulate the properties of this logger before calling the various methods of the API:

     Logger cl = Logger.getLogger("com.sun.pkg.client");
     cl.setLevel(Level.FINER);

Limitations

The pkg Java API is not (yet) a complete implementation of the client side capabilities of the Image Packaging System. Here is a partial list of the limitations of the API. The number in parenthesis is the issue that is tracking completion of that feature.

No support for making use of multiple authorities. This includes not recognizing an authority in an FMRI (544)
No access to the license to display it before an install (452)
No ability to access the list of dependencies during the install process
No support for progress tracking during an install via callbacks
No support for being able to cancel an install
No support for search (pkg search)
No support for image properties (pkg set-property)
No support for managing authorities
Cannot create an image (pkg image-create)
No image verify support (pkg verify)
No support for accessing the contents of an image (pkg contents)
The following actions are not supported: driver, user, group, legacy, hardlink
No support for optional dependencies
No support for exclude dependencies (not available in pkg(5) either)
No support for filters
No check for action duplicates in packages that are being installed
No removal of implicitly created directories during package removal
No support for ZFS boot environments
No support for package rename records in catalogs
Installed packages are not included in inventory if they are not in the catalog
