Package ghidra.framework

Class Application

  • public class Application
extends java.lang.Object
    The Application class provides a variety of static convenience methods for accessing Application elements that can be used once the initializeApplication(utility.application.ApplicationLayout, ghidra.framework.ApplicationConfiguration) call has been made.

    In order to initialize an application, an ApplicationLayout and an ApplicationConfiguration must be provided. The layout and configuration come in a variety of flavors, and are what makes the Application class usable across a range of tools.

    Example use case: 

       ApplicationLayout layout = new GhidraApplicationLayout();
   ApplicationConfiguration configuration = new GhidraApplicationConfiguration();
   Application.initalizeApplication(layout, configuration);

    • Method Detail

      • initializeApplication

        public static void initializeApplication​(ApplicationLayout layout,
                                         ApplicationConfiguration configuration)
        Initializes the application. The static methods of this class cannot be used until the application is initialized.
        Parameters:
        layout - The application layout to be used by the application.
        configuration - The application configuration to be used by the application.

      • isInitialized

        public static boolean isInitialized()
        Checks to see if the application has been initialized.
        Returns:
        true if the application has been initialized; otherwise, false.

      • initializeLogging

        public static void initializeLogging​(java.io.File logFile,
                                     java.io.File scriptLogFile)
        If the Application was previously initialized with logging disabled, this method may be used to perform delayed logging initialization.
        Parameters:
        logFile - application log file, if null the default application.log will be stored within the user's application settings directory
        scriptLogFile - scripting log file, if null the default script.log will be stored within the user's application settings directory
        Throws:
        AssertException - if Application has not yet been initialized, or logging was previously configured for the application.

      • getApplicationRootDirectories

        public static java.util.Collection<ResourceFile> getApplicationRootDirectories()
        Returns a list of the application root directories. An application root directory is a directory containing one or more modules. Applications support multiple application root directories so that it can contain modules that don't have a common file system root. This is useful if the application contains modules from more than one source code repository. Application roots are returned in the order they appear in the classpath.
        Returns:
        a list of root directories containing modules for this application.

      • getApplicationRootDirectory

        public static ResourceFile getApplicationRootDirectory()
        Returns the application root directory. An application root directory is a directory containing one or more modules. In development mode there may be multiple application root directories, which can be retrieved via getApplicationRootDirectories().

        In an installation of the application, there will only be one application root directory.

        Note: Be sure you understand that there may be multiple application root directories in development mode. In general you should not be using this method for searching for files yourself, but instead using the various find* methods of this class.

        Returns:
        Returns the application root directory.

      • getUserTempDirectory

        public static java.io.File getUserTempDirectory()
        Returns the temporary directory specific to the user and the application. Directory has name of <username>-<appname> This directory may be removed at system reboot or during periodic system cleanup of unused temp files. This directory is specific to the application name but not the version. Resources stored within this directory should utilize some form of access locking or unique naming. Transient resources should be deleted when no longer in use.
        Returns:
        temp directory

      • getUserCacheDirectory

        public static java.io.File getUserCacheDirectory()

This directory is specific to the application name but not the version. Resources stored within this directory should utilize some form of access locking and/or unique naming.
        Returns:
        cache directory
