Class AprLibrary

java.lang.Object
org.apache.mina.transport.socket.apr.AprLibrary
class AprLibrary extends Object
Internal singleton used for initializing correctly the APR native library and the associated root memory pool. It'll finalize nicely the native resources (libraries and memory pools). Each memory pool used in the APR transport module needs to be children of the root pool AprLibrary#getRootPool().

    • AprLibrary

      private AprLibrary()
      APR library singleton constructor. Called only when accessing the singleton the first time. It's initializing an APR memory pool for the whole package (a.k.a mother or root pool).

  • Method Details

    • getInstance

      static AprLibrary getInstance()
      get the shared instance of APR library, if none, initialize one
      Returns:
      the current APR library singleton

    • initialize

      private static void initialize()
      initialize the APR Library by loading the associated native libraries and creating the associated singleton

    • isInitialized

      static boolean isInitialized()
      is the APR library was initialized.
      Returns:
      true if the Library is initialized, false otherwise

    • finalize

      protected void finalize() throws Throwable
      Overrides:
      finalize in class Object
      Throws:
      Throwable

    • getRootPool

      long getRootPool()
      get the package wide root pool, the mother of all the pool created in APR transport module.
      Returns:
      number identifying the root pool
