I have json file for the schema that looks like the following:
{
"$schema": "http://json-schema.org/draft-04/schema#";,
"definitions": {
"stats": {
"type": "object",
"additionalProperties": false,
"properties": {
"id": {
"type": "string"
},
"bin_qualifier": {
"type": "string"
}
}
}
},
"additionalProperties": false,
"description": "attributes",
"type": "object",
"properties": {
"id": {
"type": "string",
"required": true,
},
"create_date": {
"type": "integer",
"javaType": "java.math.BigInteger",
"required": true
}
}
}
How can I add this schema for JsonTreeReader?
