  • Method Details

    • setLockDir

      void setLockDir(File lockDir)

    • create

      GHLock create(String fileName, boolean writeAccess)
      This creates a file for write or read locks depending on the specified writeAccess property. Important note: even for read locks we need write access to the underlying filesystem in order to avoid writes from other processes.

      void forceRemove(String fileName, boolean writeAccess)
      Removes the specified lock. Note: on windows we cannot forcefully remove an unreleased native lock
