Signature
long integralLong(PropertyAtomLong pal, long stime, long etime, int sample_rate,
boolean bound_by_stime)
Domain
ACTION, CONDITION, QUERY, BUI
Description
This method returns the integral of values in the history of a property atom over a given
time interval [stime, etime]. we are dealing with discrete steps so just a summation of all the terms each
multiplied with the interval(milliseconds) is sufficient.
Parameters
| Name | Type | Description |
|---|
pal | PropertyAtomLong | The property to check for the value of. |
stime | long | start time of the interval, 0 means use oldest value's timestamp as start time. |
etime | long | end time of the interval, 0 means use newest value's timestamp as end time. |
sample_rate | int | sample rate for the interval should be greater than 0. |
bound_by_stime | boolean | true implies for stime less than oldest value's time stamp[t0] use t0. |
Returns
| Type | Description |
|---|
long | returns the calculated value. |
Cautions
If the values are too large the sum might overflow, also if value did not exist thourgh entire
interval an exception is thrown. 'interval' precision is in milliseconds.
