Masking Functions

Masks are the basic "building-block" algorithms provided by DataMasque for generating and manipulating column values. Multiple masks can be combined in a list to create a pipeline of transformations on the data, or combined using combinator masks to build up more complex output values.


Mask algorithms are defined by their type parameter - this parameter is common to (and required by) all masks:

  • type (required) determines the type of mask, and therefore what other parameters can be specified.

Note: Masks operate by either manipulating the original column value, or by generating an entirely new value that replaces the original value. The behaviour depends on the mask type.
