ecflow.RepeatDateTime

class ecflow.RepeatDateTime

Bases: instance

Allows a node to be repeated based on date+time instants (using yyyymmddTHHMMSS format).

A node can only have one repeat. The repeat name can be referenced in trigger expressions. The trigger expression referencing a RepeatDate will use date arithmetic Here (/suite/family:YMD + 1) uses date arithmetic only, the result is still an integer

trigger /suite/family:YMD + 1 > 20190101

Constructor:

RepeatDateTime(variable, start, end[, step])
   string variable:     The name of the repeat. The Repeat can referenced in
                        in trigger expressions using the variable name
   int start:           Start date+time instant, formatted as yyyymmddTHHMMSS
   int end:             End date+time instant, formatted as yyyymmddTHHMMSS
   int step:            The increment duration used to update the instant when iterating
                        Formatted as HH:MM.SS, if not provided default delta is '24:00:00'.

Exception:

• Throws a RuntimeError if start/end are not valid date+time instants

• Throws a RuntimeError if delta is not a valid duration

Usage:

rep = RepeatDateTime('DATETIME', '20050130T000000', '20050203T000000')
rep = RepeatDateTime('DATETIME', '20050130T000000', '20050203T000000', '48:00:00')
t = Task('t1',
         RepeatDateTime('DATETIME', '20050130T000000', '20050203T120000', '1:00:00'))

RepeatDateTime.end((RepeatDateTime)arg1) → int :

Return the end date as an integer (i.e. seconds since 19700101T000000)

RepeatDateTime.name((RepeatDateTime)arg1) → str :

Return the name of the repeat.

RepeatDateTime.start((RepeatDateTime)arg1) → int :

Return the start date as an integer (i.e. seconds since 19700101T000000)

RepeatDateTime.step((RepeatDateTime)arg1) → int :

Return the step increment (in seconds). This is used to update the repeat, until end instant is reached
