## org.apache.commons.configuration
Interface PropertiesConfiguration.IOFactory

All Known Implementing Classes:
  PropertiesConfiguration.DefaultIOFactory

Enclosing class:
  PropertiesConfiguration

    public static interface PropertiesConfiguration.IOFactory

Definition of an interface that allows customization of read and write operations.

For reading and writing properties files the inner classes `PropertiesReader` and `PropertiesWriter` are used. This interface defines factory methods for creating both a `PropertiesReader` and a `PropertiesWriter`. An object implementing this interface can be passed to the `setIOFactory()` method of `PropertiesConfiguration`. Every time the configuration is read or written the `IOFactory` is asked to create the appropriate reader or writer object. This provides an opportunity to inject custom reader or writer implementations.

Since:
  1.7

Method Summary
`PropertiesConfiguration.PropertiesReader` | `createPropertiesReader(Reader in, char delimiter)` Creates a `PropertiesReader` for reading a properties file.
`PropertiesConfiguration.PropertiesWriter` | `createPropertiesWriter(Writer out, char delimiter)` Creates a `PropertiesWriter` for writing a properties file.

Method Detail

### createPropertiesReader

    PropertiesConfiguration.PropertiesReader createPropertiesReader(Reader in,
                                                                    char delimiter)

  Creates a `PropertiesReader` for reading a properties file. This method is called whenever the `PropertiesConfiguration` is loaded. The reader returned by this method is then used for parsing the properties file.

  Parameters:
    `in` - the underlying reader (of the properties file)
    `delimiter` - the delimiter character for list parsing
  Returns:
    the `PropertiesReader` for loading the configuration

### createPropertiesWriter

    PropertiesConfiguration.PropertiesWriter createPropertiesWriter(Writer out,
                                                                    char delimiter)

  Creates a `PropertiesWriter` for writing a properties file. This method is called before the `PropertiesConfiguration` is saved. The writer returned by this method is then used for writing the properties file.

  Parameters:
    `out` - the underlying writer (to the properties file)
    `delimiter` - the delimiter character for list parsing
  Returns:
    the `PropertiesWriter` for saving the configuration
