    • getCommandLineArgs

      String[] getCommandLineArgs()
      Returns all command line arguments specified when the running framework was started.
      Returns:
      the array of command line arguments.
    • getFrameworkArgs

      String[] getFrameworkArgs()
      Returns the arguments consumed by the framework implementation itself. Which arguments are consumed is implementation specific.
      Returns:
      the array of command line arguments consumed by the framework.
    • getNonFrameworkArgs

      String[] getNonFrameworkArgs()
      Returns the arguments not consumed by the framework implementation itself. Which arguments are consumed is implementation specific.
      Returns:
      the array of command line arguments not consumed by the framework.
    • getOSArch

      String getOSArch()
      Returns the string name of the current system architecture. The value is a user-defined string if the architecture is specified on the command line, otherwise it is the value returned by java.lang.System.getProperty("os.arch").
      Returns:
      the string name of the current system architecture
    • getNL

      String getNL()
      Returns the string name of the current locale for use in finding files whose path starts with $nl$.
      Returns:
      the string name of the current locale
    • getOS

      String getOS()
      Returns the string name of the current operating system for use in finding files whose path starts with $os$. Return Constants.OS_UNKNOWN if the operating system cannot be determined.

      The value may indicate one of the operating systems known to the platform (as specified in org.eclipse.core.runtime.Platform#knownOSValues) or a user-defined string if the operating system name is specified on the command line.

      Returns:
      the string name of the current operating system
    • getWS

      String getWS()
      Returns the string name of the current window system for use in finding files whose path starts with $ws$. Return null if the window system cannot be determined.
      Returns:
      the string name of the current window system or null
    • inDebugMode

      boolean inDebugMode()
      Returns true if the framework is in debug mode and false otherwise.
      Returns:
      whether or not the framework is in debug mode
    • inDevelopmentMode

      boolean inDevelopmentMode()
      Returns true if the framework is in development mode and false otherwise.
      Returns:
      whether or not the framework is in development mode
    • getProperty

      String getProperty(String key)
      Returns the value for the specified property. Environment Properties are backed by the Java system properties. When the option osgi.framework.useSystemProperties is used then the environment properties are specific for each instance of the framework.

      This method should be used instead of the System.getProperty(String) method to avoid the global nature of system properties.

      Parameters:
      key - the property key
      Returns:
      the value of the property, or null
      Since:
      3.4
    • setProperty

      String setProperty(String key, String value)
      Sets the value for the specified property. Environment Properties are backed by the Java system properties. When the option osgi.framework.useSystemProperties is used then the environment properties are specific for each instance of the framework.

      This method should be used instead of the System.setProperty(String, String) method to avoid the global nature of system properties.

      Parameters:
      key - the property key
      value - the value of the property
      Returns:
      the old value of the property, or null
