Usage

From source file:io.cloudslang.content.json.actions.AddJsonPropertyToObject.java

/**
 * Inserts a new name/value property into a JSON object, where the value is a valid JSON string.
 * If the <b>newPropertyValue</b> input is not a valid string representation of a JSON object, the operation fails.
 * This operation can be used to add a property with a simple string value.
 *
 * @param jsonObject       The string representation of a JSON object.
 *                         Objects in JSON are a collection of name value pairs, separated by a colon and surrounded with curly brackets {}.
 *                         The name must be a string value, and the value can be a single string or any valid JSON object or array.
 *                         Examples: {"one":1, "two":2}, {"one":{"a":"a","B":"B"}, "two":"two", "three":[1,2,3.4]}
 * @param newPropertyName  The name of the new property that will be added to the JSON object.
 *                         Examples: property1, some_property, another property
 * @param newPropertyValue The value for the new property. This must be a valid JSON object.
 *                         Examples: 1, {"A":"A"}, [1,2,3,4]
 * @return a map containing the output of the operation. Keys present in the map are:
 * <p/>/*  w  w  w .  j a va2  s  . c  o m*/
 * <br><br><b>returnResult</b> - This will contain the JSON with the new property/value added.
 * <br><b>exception</b> - In case of success response, this result is empty. In case of failure response,
 * this result contains the java stack trace of the runtime exception.
 * <br><br><b>returnCode</b> - The returnCode of the operation: 0 for success, -1 for failure.
