/** |

|
|
|
* The IntervalValuator sums the aggregate value of an event by dividing time |
|
16
|
|
|
* in discreet intervals (using \DateInterval) and then assigning value to those |
|
17
|
|
|
* intervals based on the value the unit has during that interval. |
|
18
|
|
|
* |
|
19
|
|
|
* For example, if we are dealing with a hotel room and want to calculate nightly rates |
|
20
|
|
|
* we can set the date interval to P1D. We will query the calendar for events whose value |
|
21
|
|
|
* represents prices over that period and the split the time in 1-day intervals and sum up |
|
22
|
|
|
* accordingly. |
|
23
|
|
|
* |
|
24
|
|
|
* If we are selling activities at 15m intervals we can set the interval at PT15M and we would |
|
25
|
|
|
* be splitting events on 15m intervals and would assign the value of each interval to the value |
|
26
|
|
|
* of the event during that interval. |

This check looks for variable assignements that are either overwritten by other assignments or where the variable is not used subsequently.
Both the
$myVarassignment in line 1 and the$higherassignment in line 2 are dead. The first because$myVaris never used and the second because$higheris always overwritten for every possible time line.
