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.

Method Summary

Modifier and Type	Method	Description
PropertiesConfiguration.PropertiesReader	createPropertiesReader(java.io.Reader in, char delimiter)	Creates a PropertiesReader for reading a properties file.
PropertiesConfiguration.PropertiesWriter	createPropertiesWriter(java.io.Writer out, char delimiter)	Creates a PropertiesWriter for writing a properties file.

Method Detail

createPropertiesReader

PropertiesConfiguration.PropertiesReader createPropertiesReader(java.io.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(java.io.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
