    • Method Detail

      • threadSafeTerminate

        public static void threadSafeTerminate()
        Allows for thread safe termination when other threads may be attempting clean-up concurrently with the current thread. Waits for any threads currently holding the clean-up lock to release the lock and then calls terminate().
      • terminate

        public static void terminate()
        Destroys Tomcat Native's global APR pool. This has to be the last call to TCN library. This will destroy any APR root pools that have not been explicitly destroyed.

        This method should only be used if the caller is certain that all other threads have finished using the native library.

      • versionString

        public static java.lang.String versionString()
      • aprVersionString

        public static java.lang.String aprVersionString()
      • globalPool

        @Deprecated
        public static long globalPool()
        Deprecated.
      • initialize

        public static boolean initialize​(java.lang.String libraryName)
                                  throws java.lang.Exception
        Setup any APR internal data structures. This MUST be the first function called for any APR library.
        Parameters:
        libraryName - the name of the library to load
        Returns:
        true if the native code was initialized successfully otherwise false
        Throws:
        java.lang.Exception - if a problem occurred during initialization
      • tryCleanUpLock

        public static boolean tryCleanUpLock​(long cleanupGeneration)
      • getGeneration

        public static long getGeneration()
      • returnCleanUpLock

        public static void returnCleanUpLock()
      • load

        @Deprecated
        public static void load​(java.lang.String filename)
        Deprecated.
        Unused. Will be removed in Tomcat 10.1.x
        Calls System.load(filename). System.load() associates the loaded library with the class loader of the class that called the System method. A native library may not be loaded by more than one class loader, so calling the System method from a class that was loaded by a Webapp class loader will make it impossible for other Webapps to load it. Using this method will load the native library via a shared class loader (typically the Common class loader, but may vary in some configurations), so that it can be loaded by multiple Webapps.
        Parameters:
        filename - - absolute path of the native library
      • loadLibrary

        @Deprecated
        public static void loadLibrary​(java.lang.String libname)
        Deprecated.
        Unused. Will be removed in Tomcat 10.1.x
        Calls System.loadLibrary(libname). System.loadLibrary() associates the loaded library with the class loader of the class that called the System method. A native library may not be loaded by more than one class loader, so calling the System method from a class that was loaded by a Webapp class loader will make it impossible for other Webapps to load it. Using this method will load the native library via a shared class loader (typically the Common class loader, but may vary in some configurations), so that it can be loaded by multiple Webapps.
        Parameters:
        libname - - the name of the native library
