Description

Example in user guide about using custom IOFactory doesn't work.

Link:
https://commons.apache.org/proper/commons-configuration/userguide/howto_properties.html#Custom_properties_readers_and_writers

When you set an IOFactory like this:

params.properties()
.setFileName("myfile.properties")
.setIOFactory(new WhitespaceIOFactory())

this custom IOFactory won't be set in your PropertiesConfiguration because
the constant PropertiesBuilderParametersImpl.PROP_IO_FACTORY has the value:
"iOFactory".

FileBasedConfigurationBuilder tries to set the property "iOFactory" of PropertiesConfiguration .
The method setiOFactory() exists not.

I have found a workaround, maybe this can explain better the problem:

//New subclass:
public class PropertiesConfigurationOk extends PropertiesConfiguration {
public void setiOFactory(IOFactory ioFactory)

{ super.setIOFactory(ioFactory); }

}

//Usage of new subclass:
FileBasedConfigurationBuilder<FileBasedConfiguration> builder = new FileBasedConfigurationBuilder<FileBasedConfiguration>(PropertiesConfigurationOk.class) .configure(propertiesBuilderParameters);

PropertiesConfiguration config = builder.getConfiguration();
