Array JSON Mask (ArrayJsonMaskGenerator)

The Array JSON Mask generator is a composite generator. It is a version of the JSON Mask generator that can be used for array values. It runs a selected generator on values that match a specified JSONPath.

Link object structure

For the Array JSON Mask generator, you provide a link object for each sub-generator configuration.

The generator does not itself support consistency or differential privacy.

The metadata object is populated from the JsonMaskMetadata object. For the Array JSON Mask generator, metadata includes:

• pathExpression, which is the path expression that identifies the value to apply the sub-generator to.

• The types of values to apply the sub-generator to.

• The subGeneratorMetadata object, which identifies and configures the sub-generator.

Here is the basic structure of a link object for an Array JSON Mask sub-generator.

{
  "schema": "string",
  "table": "string",
  "column": "string",
  "metadata": {
    "generatorId": "ArrayJsonMaskGenerator",
    "presetId": "ArrayJsonMaskGenerator",
    "customValueProcessor": "string", //If custom value processor applied to the generator
    "pathExpression": "string",
    "jsonFilterTypes": [ enum ],
    "subGeneratorMetadata": {
      "generatorId": "string",
      "presetId": "string",
      //Metadata for the selected sub-generator
      "customValueProcessor": "string" //If custom value processor applied to the sub-generator
    }
  }
}

Example replacement

The following example replacement applies the built-in generator preset for the Geo generator to the value at the specified path expression.

The configuration for the Geo generator indicates that it is a latitude value.

{
  "name": "location",
  "schema": "public",
  "table": "offices",
  "links": [
    {
      "schema": "public",
      "table": "offices",
      "column": "location",
      "metadata": {
        "generatorId": "ArrayJsonMaskGenerator",
        "presetId": "ArrayJsonMaskGenerator",
        "pathExpression": "$.value",
        "jsonFilterTypes": [
          0
        ],
        "subGeneratorMetadata": {
          "presetId": "GeoGenerator",
          "generatorId": "GeoGenerator",
          "geoType": "Latitude"
        }
      }
    }
  ]
}
