      Add a child Configuration to this configuration element.
      Parameters:
      configuration - a Configuration value

    • addAll

      void addAll(Configuration other)
      Add all the attributes, children and value from specified configuration element to current configuration element.

    • getMutableChild

      MutableConfiguration getMutableChild(String name) throws ConfigurationException
      Equivalent to getMutableChild( name, true )
      Throws:
      ConfigurationException

    • getMutableChild

      MutableConfiguration getMutableChild(String name, boolean autoCreate) throws ConfigurationException
      Gets a child node of this configuration. If a mutable child with the given name exists, it is returned. If an immutable child with the given name exists, it is converted into a mutable child and returned. In this case, the immutable child will be replaced with the mutable child in this configuration (that is, it will be as if the child node always had been mutable). If no child with the given name exists, and autoCreate is true, a new mutable child is created and added to this configuration before being returned.
      Parameters:
      name - the name of the child.
      autoCreate - set to true to create the child node if it doesn't exist.
      Returns:
      the child MutableConfiguration, or null if autoCreate was false and no child by the given name existed.
      Throws:
      ConfigurationException - if an error occurrs.

    • getMutableChildren

      MutableConfiguration[] getMutableChildren() throws ConfigurationException
      Returns an array of mutable children. Immutable children are converted just as for getMutableChild.
      Throws:
      ConfigurationException - if an error occurrs.

    • getMutableChildren

      MutableConfiguration[] getMutableChildren(String name) throws ConfigurationException
      Returns an array of mutable children with the given name. Immutable children are converted just as for getMutableChild.
      Throws:
      ConfigurationException - if an error occurrs.
