_checksetNestedLists(self, value)
The rule is that if there are nested lists then they must not contain GangaObjects, as this corrupts the repository

createSubjob(self, job)
Create a new subjob by copying the master job and setting all fields correctly.

source code

split(self, job)
Return a list of subjobs generated from a master job.

validatedSplit(self, job)
Perform splitting using the split() method and validate the mutability invariants.

Method Details

[hide private]

split(self, job)

source code

Return a list of subjobs generated from a master job. The original master job should not be modified. This method should be implemented in the derived classes.

Splitter changes certain parts of the subjobs i.e. mutates certain properties (otherwise all subjobs would be the same). Only these properties may be mutated which are declared 'splitable' in the schema. This restriction applies to application objects to avoid inconsistencies if application handler is not able to deal with modified arguments.

In the current implementation the type of the backend cannot be changed either.

validatedSplit(self, job)

source code

Perform splitting using the split() method and validate the mutability invariants. If the invariants are broken (or exception occurs in the split() method) then SplittingError exception is raised. This method is called directly by the framework and should not be modified in the derived classes.
