TimeRecorder (Central monitoring (integration) 0.3.0 Test API)

java.lang.Object
- test.de.iip_ecosphere.platform.monitoring.TimeRecorder

```
public class TimeRecorder
extends Object
```
Class to determine the response times.
This class connects to the AAS similarly to the AasJerseyClientV2, but instead of printing the values on screen, it records the time required to retrieve and parse the data.

Modifier and Type	Method and Description
`private void`	`add()` Adds AAS property values to objects and arrays.
`private void`	`initialize()` Initializes the measurement.
`static void`	`main(String[] args)` Executes the TimeRecorder. This class will connect to the AAS and retrieve all the metrics, recording the time required to both retrieve the data and parse it.

```
public static void main(String[] args)
                 throws IOException,
                        ExecutionException
```
    Executes the TimeRecorder.
    This class will connect to the AAS and retrieve all the metrics, recording the time required to both retrieve the data and parse it. The mean time is calculated and printed on screen after the execution for each of the different types of meters. This entire process is repeated LOOP amount of times before printing the mean, ensuring that the data is more accurate.
    
    Parameters:
    
    args - command line arguments, never used
    
    Throws:
    
    IOException - if it occurs when retrieving the registry
    
    ExecutionException - if it occurs when retrieving the properties
  - initialize
```
private void initialize()
                 throws IOException
```
    Initializes the measurement.
    
    Throws:
    
    IOException - if it occurs when retrieving the registry
  - measure
```
private void measure()
              throws ExecutionException
```
    Initializes and measures.
    
    Throws:
    
    ExecutionException - if it occurs when retrieving the properties
  - printResults
```
private void printResults()
```
    Print out the results.
  - add
```
private void add()
          throws ExecutionException
```
    Adds AAS property values to objects and arrays.
    
    Throws:
    
    ExecutionException - if some submodel operation fails
  - retrieveObject
```
private static javax.json.JsonObject retrieveObject(Object json)
```
    Creates a JSON Object from a retrieved String.
    
    Parameters:
    
    json - String representing the JSON Object
    
    Returns:
    
    a JsonObject parsed from the String
  - retrieveArray
```
private static javax.json.JsonArray retrieveArray(Object json)
```
    Creates a JSON Array from a retrieved String.
    
    Parameters:
    
    json - String representing the JSON Array
    
    Returns:
    
    a JsonArray parsed from the String
  - retrieveTags
```
private static String[] retrieveTags(javax.json.JsonArray tagsArr)
```
    Retrieves the Tags stored in a JsonArray as a String array needed for the method.
    
    Parameters:
    
    tagsArr - JsonArray with the tags
    
    Returns:
    
    String array with the retrieved tags
