DataFilters

Data Filters

Data filters are modules which narrow area on which comparison will be performed.

They are nested in Comparators and apply only to instance of comparator in which they are defined.

Each data filter consists of two elements:

• module name,
• parameters.

Module name

This name is unique identifier for each data filter (and each module in compare phase).

Parameters

This is set of key-value pairs using which user can pass some configuration and information to data filter. Parameters can be divided into two groups:

• mandatory - parameters without which filtering will be not possible,
• optional - passing this parameter is not obligatory, usually they trigger some functionality extension.
