Package org.apache.uima.pear.tools

Class InstallationController

java.lang.Object
org.apache.uima.pear.tools.InstallationController
public class InstallationController extends Object
The InstallationController class allows installing PEAR files that contain UIMA compliant components.
Note: current version works both in Windows and Linux.
This class may be used in the following ways:
  • As a standalone Java application -
    java -DUIMA_HOME=%UIMA_HOME% org.apache.uima.pear.tools.InstallationController {-local pear_file | component_id} [-root] [installation_directory]
    where the -local pear_file option allows to install local PEAR file in the local file system (without using SITH services);
    the component_id is the ID of the component to be installed using SITH services;
    the -root option enables component installation directly in the specified installation directory, as opposed to installing component in a component_id subdirectory of the specified installation directory;
    the installation_directory is the directory where the new component will be installed - if the -root option is specified, the component is installed in this directory, otherwise it is installed in a component_id subdirectory of this directory; by default - current working directory.
  • As a Java object -
    in this case, the caller is expected to set the UIMA_HOME variable, using the setUimaHomePath() method, immediately after creating a new instance of the InstallationController class.
    Installation is performed by using the installComponent() method.
    Installation verification is performed by using the verifyComponent() method.
    Error messages can be retrieved by using the getInstallationMsg() and getVerificationMsg() methods.
    Note 1: Starting from version 0.6, the InstallationController class utilizes intra-process message routing (see MessageRouter). Applications need to call the terminate() method on each instance of the InstallationController class after all their operations are completed.
    The application can get output and error messages, printed by the InstallationController, by adding standard channel listeners (see the addMsgListener() method). By default, the output and error messages are printed to the standard console streams. Alternatively, the application can use the InstallationController constructor that accepts a custom message listener. In this case, the output and error messages will not be printed to the standard console streams.
    Note 2: Starting from version 1.4, the InstallationController class defines the InstallationController.PackageSelector interface and allows to plug-in custom package selectors for manually or automatically selecting root directories of installed PEAR packages, as well as PEAR package files that need to be installed.
    Note 2: Starting from version 1.5, the InstallationController class defines the InstallationController.InstallationMonitor interface and allows to plug-in custom installation monitors for reporting component installation status and location of installed components.

    • InstallationController

      public InstallationController(String componentId, String rootDirPath)
      Constructs an instance of the InstallationController class for a given component and a given installation root directory.
