DataFilters

Data Filters

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

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

Each data filter consists of two elements:

• module name,
• parameters.

Module name

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

Parameters

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

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