JSON Path Expression Evaluation

List of possible expressions used along with the previously mentioned operators, based on above JSON input payload.

For Sample 1:

Contains:
```
$.network[?(@.type =~ /^.*ip.*$/i)]
```
The expression looks for the element "type" under "network" that contains the "ip" string.
Match on prefix:
```
$.network[?(@.direction =~ /^.*inbound-.*$/i)
```
The expression looks for the element "direction" under "network" that contains the prefix "inbound-" string.
Match on suffix:
```
$.network[?(@.direction =~ /^.*-outbound.*$/i)
```
The expression looks for the element "direction" under "network" that contains the suffix "-outbound" string.
Match on numeric value:
```
$.network[?(@.iana_number > 10 )
```
The expression looks for the element "iana_number" under "network" that contains values greater than "10".
Match on string value:
```
$.network[?(@.type == 'ipv6')
```
The expression looks for the element "type" under "network" that contains exactly the "ipv6" string.
Match on value and suffix regex:
```
$.network[?(@.iana_number < 10 || @.direction =~ /^.*-outbound.*$/i)
```
The expression looks for the element "iana_number" smaller than "10" and for the element "direction" that contains the suffix "-outbound" string, both under "network".

Note: For more information, refer to the JSONPath documentation. You can evaluate the expressions using the Jayway JsonPath Evaluator open source tool.

For Sample 2:

Set ACTIVE, INACTIVE value based on key-value of input data using concat:

$.concat(($.[?(@.clearTime == '')].concat(\"ACTIVE\")), ($.[?(@.clearTime != '')].concat(\"INACTIVE\")))

Calculate timestamp by adding offset time using concat and transform time stamp using custom function transform_date:
```
$.concat(@.alarmTime, @.alarmTimeOffset).transform_date(\"yyyy-MM-dd HH:mm:ssXXX\")
```
Applying mathematical functions like min(), max(), avg(), stddev() on array like object:
```
$.parameters.avg()
```
