}

Example 3 with JsonNode

use of org.ballerinalang.model.util.JsonNode in project ballerina by ballerina-lang.

the class BJSON method stringValue.

@Override
public String stringValue() {
    JsonNode node = this.value();
    if (node.isValueNode()) {
        return this.value().asText();
    } else if (!node.isObject()) {
        return node.toString();
    }
    BStructType constrainedType = (BStructType) ((BJSONType) this.type).getConstrainedType();
    if (constrainedType == null) {
        return node.toString();
    }
    // If constrained JSON, print the only the fields in the constrained type.
    StringJoiner sj = new StringJoiner(",", "{", "}");
    for (StructField field : constrainedType.getStructFields()) {
        String key = field.fieldName;
        String stringValue = this.value().get(key).toString();
        sj.add("\"" + key + "\":" + stringValue);
    }
    return sj.toString();
}
