HStore Mask (HStoreMaskGenerator)

The HStore Mask generator runs selected generators on specified key values in an HStore column in a PostgreSQL database. HStore columns contain a set of key-value pairs.
Link object structure
For the HStore Mask generator, there is a link object for each path expression value to assign a generator to. pathExpression contains the expression, and subGeneratorId identifies the generator to assign to the value for that path expression.
The HStore Mask generator does not itself support consistency or differential privacy.
The metadata object is populated from the HStoreMaskMetadata object, which includes:
The sub-generator type to apply to the value from pathExpression.
The subGeneratorMetadata object, which contains the generator configuration for the selected sub-generator.

Example replacement
In the following example replacement for the HStore Mask generator:
The Random Integer generator is assigned to the value of the pages path expression. The generator uses values between 300 and 500.
The Character Scramble generator is assigned to the value of the title path expression. Consistency is disabled.
