Detailed Description

The FileJoinManager is responsible for joining/grouping documents using files on the filesystem

Constructor & Destructor Documentation

FileJoinManager()

FileJoinManager::FileJoinManager	(	const std::string &	name,

	)

Initializes the FileJoinManager and creates an temporary directory to store temporary files within

Parameters

name	Name/Identifier of the join. It is used to create the directory.
valProv	The IValueProvider to receive the join values from.
