Method Detail

postProcessParsedConfig

protected Map<String,Object> postProcessParsedConfig(Map<String,Object> parsedValues)

Description copied from class: AbstractConfig

Called directly after user configs got parsed (and thus default values got set). This allows to change default values for "secondary defaults" if required.

Overrides:

postProcessParsedConfig in class AbstractConfig

Parameters:

parsedValues - unmodifiable map of current configuration

Returns:

a map of updates that should be applied to the configuration (will be validated to prevent bad updates)
