- ## Constructor Details

  - ### JSONConfiguration

    Creates a new instance of `JSONConfiguration`.

  - ### JSONConfiguration

    public JSONConfiguration(HierarchicalConfiguration<ImmutableNode> c)
    Creates a new instance of `JSONConfiguration` as a copy of the specified configuration.
    Parameters:
      `c` - the configuration to be copied

- ## Method Details

  - ### read

    public void read(InputStream in) throws ConfigurationException
    Loads the configuration from the given input stream.
    Specified by:
      `read` in interface `InputStreamSupport`
    Parameters:
      `in` - the input stream
    Throws:
      `ConfigurationException` - if an error occurs

  - ### read

    public void read(Reader in) throws ConfigurationException
    Description copied from interface: `FileBased`
    Reads the content of this object from the given reader. Client code should not call this method directly, but use a `FileHandler` for reading data.
    Specified by:
      `read` in interface `FileBased`
    Parameters:
      `in` - the reader
    Throws:
      `ConfigurationException` - if a non-I/O related problem occurs, for example the data read does not have the expected format

  - ### write

    public void write(Writer out) throws ConfigurationException, IOException
    Description copied from interface: `FileBased`
    Writes the content of this object to the given writer. Client code should not call this method directly, but use a `FileHandler` for writing data.
    Specified by:
      `write` in interface `FileBased`
    Parameters:
      `out` - the writer
    Throws:
      `ConfigurationException` - if a non-I/O related problem occurs, for example the data read does not have the expected format
      `IOException` - if an I/O error occurs.
