Usage

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

/**
 * This operation accepts an object in the JavaScript Object Notation format (JSON) and returns a value for the specified key.
 *
 * @param object 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 key    The key in the object to get the value of.
 *               Examples: city, location[0].city
 * @return a map containing the output of the operation. Keys present in the map are:
 * <p/>//from   ww w  . j  ava 2 s . co m
 * <br><br><b>returnResult</b> - This will contain the value for the specified key in the object.
 * <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.
