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.
For the Array JSON Mask generator, you provide a link object for each sub-generator configuration.
The link object identifies the path expression and the sub-generator to run on the matching values.
The Array JSON Mask generator does not itself support consistency or differential privacy.
- The sub-generator type.
- The types of values to apply the sub-generator to.
- The
subGeneratorMetadataobject, which contains the generator configuration for the sub-generator.
Here is the basic structure of a link object for an Array JSON Mask sub-generator.
{
"generatorId": "ArrayJsonMaskGenerator",
"presetId": "ArrayJsonMaskGenerator",
"schema": "string",
"table": "string",
"column": "string",
"pathExpression": "string",
"subGeneratorId": "string",
"metadata": {
"subPresetId": "string",
"subGeneratorId": "string",
"jsonFilterTypes": [ enum ],
"subGeneratorMetadata": {
//Metadata for the selected sub-generator type
}
},
"customValueProcessor": "string", //If custom value processor applied to the generator
"customSubGeneratorValueProcessor": "string" //If custom value processor applied to the sub-generator
}
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": [
{
"generatorId": "ArrayJsonMaskGenerator",
"presetId": "ArrayJsonMaskGenerator",
"schema": "public",
"table": "offices",
"column": "location",
"pathExpression": "$.value",
"subGeneratorId": "GeoGenerator",
"metadata": {
"subPresetId": "GeoGenerator",

"jsonFilterTypes": [

"subGeneratorMetadata": {
"geoType": "Latitude"
