Parameters:

parent - the parent of the node

name - the name of the node

Returns:

the newly created node

Throws:

InvalidParameterException - if parent is not assignable from FileFolder

getFileExtension

protected abstract String getFileExtension()

Gets the file extension for the node being created by the factory. The extension is used to identify the type of node contained within the document (ConfigurationDocument or LinkNode at this time).

Returns:

String the file extension starting with a '.'

getConfigurationFormatService

protected ConfigurationFormatService getConfigurationFormatService()

Method that determines which ConfigurationFormatService will be used within the ConfigurationDocuments of the file package. The default implementation returns a static instance of org.sape.carbon.core.config.format.DefaultConfigurationFormatService. Override this method to change the ConfigurationFormatService used by the FileConfigurationDocument.

Returns:

ConfigurationFormatService
