- lineage(resource)[ソース]¶
Return a generator representing the lineage of the resource object implied by the
resource
argument. The generator first returnsresource
unconditionally. Then, ifresource
supplies a__parent__
attribute, return the resource represented byresource.__parent__
. If that resource has a__parent__
attribute, return that resource's parent, and so on, until the resource being inspected either has no__parent__
attribute or which has a__parent__
attribute ofNone
. For example, if the resource tree is:thing1 = Thing() thing2 = Thing() thing2.__parent__ = thing1
Calling
lineage(thing2)
will return a generator. When we turn it into a list, we will get:list(lineage(thing2)) [ <Thing object at thing2>, <Thing object at thing1> ]
