## 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.

      Internal constructor that creates an instance of the `InstallationController` class for a given component and a given installation root directory. If the `installInRootDir` flag is `true`, the component will be installed in the given root directory, otherwise the `InstallationController` will create a `component_id` subdirectory for the component code and resources. If a given custom `MessageRouter` is not `null`, the new `InstallationController` instance will use the given message router, otherwise it will create a new message router object. If a given custom message listener is not `null`, the `InstallationController` instance will send all stdout and stderr messages to the given message listener, otherwise these messages are sent to the default message listener, which prints them to the standard console streams.

If the `installInRootDir` flag is `true`, the component code and resources will be installed in the specified root directory, otherwise the `InstallationController` will create a `component_id` subdirectory for the component code and resources. If the custom message listener is not `null`, the `InstallationController` class sends all stdout and stderr messages to this message listener, otherwise these messages are sent to the default message listener, which prints them to the standard console streams.
