Methods inherited from common.database.DBMain.DBObject:
- __del__(self)
- Destructor for the DBObject
This destructor is called by the garbage collector for the transient
part of the DBObject. When it is called it calls the gc_transient()
method of the DBProxy implementation. The implementation of the
gc_transient() method can then decide what to do with the persistent
counterpart.
E.g. the database can be synchronized with its transient counterpart.
Another possibility is that the gc_transient() implementation checks
whether any attributes of a read-only object have changed since an
object was fetched from the database. If there are differences an
exception can be raised.
- __reduce__(self)
- Method necessary to create picklable objects
This mehod return a tuple containg a function object used for
unpickling and a picklable state tuple, to be used as argument
to the unpickle function. If necessary this object is registered
in the pickle cache
- as_dict(self, seqnr=1, dependency_name='', dictionary={}, allow_lazy_typed_list=False)
- Method much like the info method, but returns a dictionary.
Dictionary looks like:
{'<classname>.<property1_name>.<property2_name>': value,
'<classname>.<property2_name>.<property3_name>': value}
Problem: infinite loops for cold/flat dependencies. It seems a maximum
recursion depth limits the problem.
- commit(self)
- Commits object including objects that are referenced and have been changed.
If this object refers to other persistent object a commit() ensures that
1. ALL changes to the object and referred objects are made persistent.
2. NONE of the changed object and referred objects are made persistent.
Under normal circumstances only the first thing should ever happen.
If the second case occurs it is almost certainly because of some bug in
the routine that implements the DBProxy interface.
- get_creator(self)
- Returns the name of the user who created this object.
- get_persistent(self)
- get_project(self)
- Returns the name of the project to which this object belongs.

- Print the values of all persistent properties of the object.
level : level of introspection
doc : display docstrings for attributes
_indent : internal parameter used for formatting
_printclass : internal parameter used for formatting
- inverse_objects(self, max_results=100)
- Iterate through and return all objects that use the current object
max_results The maximum number of objects returned per query
- inverse_query(self)
- go through all inverse properties to see if this object is used
- persists(self)
- Returns whether an object is already made persistent or transient.
- recommit(self)
- Commits changes to an object, without following links.

complex computations (e.g., subtracting the two images, and
analysing the residuals)
