    • gets

      public java.lang.String gets​(java.lang.String sKey, java.lang.String sDefault, boolean bProcessQueries)
      Description copied from class: ExtProperties
      Get the String value for a given key, returning the given default value if the key is not defined. The value that is returned is also stored in a cache so that future requests to the same key will return the value from the cache. This also means that if the key is not defined then the given default value will be cached and returned the next time this function is called. null values are not cached.
      Overrides:
      gets in class ExtProperties
      Parameters:
      sKey - the key to get the value for
      sDefault - default value to return in case the key is not defined.
      bProcessQueries - flag to process or not process the database/memory cache queries
      Returns:
      value for this key

    • set

      public void set​(java.lang.String sKey, java.lang.String sValue)
      Description copied from class: ExtProperties
      Modify an entry of the dictionary.
      Overrides:
      set in class ExtProperties
      Parameters:
      sKey - key to change
      sValue - new value

    • isReadOnly

      public boolean isReadOnly()
      Description copied from class: ExtProperties

      Returns:
      true if changes are blocked

    • getProperties
