Method Detail

setConfigDirectory

void setConfigDirectory(File configDir)
                        throws Exception

Indicates the directory where ItemIndexer config files reside. ItemIndexer instances may work with their own configuration file and find them here. As a best practice it is recommended that the ItemIndexer use the name of its class in file names that it uses for configuration. It is up to the ItemIndexer to process these files. This method is called at start up time before any indexing events are fired and later any time the config file has been modified.

Parameters:

configDir - The directory where the config files reside

Throws:

Exception - Exception should be thrown if an error occurs

Parameters:
