Class StructureBase

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__

(inherited documentation)

returns a dict of the current attributes, suitable for making a shallow copy of self.

Struct attributes will not be reparented, so there are limits to what you can do with such shallow copies.

returns a dictionary mapping attribute names to copyable children.

ignoreKeys can be a set or dict of additional attribute names to ignore. The children are orphan deep copies.

returns a deep copy of self, reparented to parent.

This is a shallow wrapper around change, present for backward compatibility.

iterates over structure children of self.

To make this work, attributes containing structs must define iterChildren methods (and the others must not).

removes the parent attributes from all child structures recusively.

The struct will probably be broken after this, but this is sometimes necessary to help the python garbage collector.

In case you're asking: parent cannot be a weak reference with the current parse architecture, as it usually is the only reference to the embedding object. Yes, we should probably change that.

Special descriptor for class __provides__

The descriptor caches the implementedBy info, so that we can get declarations for objects without instance-specific interfaces a bit quicker.

__implemented__

Value:

<implementedBy gavo.base.structure.StructureBase>

managedAttrs

Value:

{'id': <gavo.base.parsecontext.IdAttribute object>}
