Create a metadata entry that contains the result of an evaluated expression implying dates.
For example, let's say you need to have a metadata entry containing a string that would express current date in the following form : YYYYMM
Well, this preprocessor is what you need.
It "evaluates" a python expression that may imply the "time" and "string" jython modules (or python 2.1).
Parameters :
| type |
DateMetadataPreproc |
| valueName |
Name of the metadata entry |
| expression |
The expression that must be evaluated |
For the example I've spoken about before ( current date => YYYYMM ), the expression attribute will take the following value : time.strftime('%Y%m',time.localtime())
If we wanted last month in the same form, we'd have to put the following expression instead:
time.strftime('%Y%m',time.localtime(time.mktime(time.localtime())-time.mktime((1970, 2, 1, 1, 0, 0, 3, 1, 0))))
