API Reference¶
Protocol APIs¶
Changed in version 4.8.0: Previously, ISized was defined here, but now it is
imported from zope.interface.common.collections. The
definition is the same.
Similarly, IReadSequence, previously defined here,
has been replaced with
zope.interface.common.sequence.IMinimalSequence.
Caution
Before version 4.8.0, most of these interfaces served as
documentation only, and were not implemented by the classes of
this package. For example, BTrees.OOBTree.BTree did not
implement IBTree. (The exceptions were the IBTreeModule
and IBTreeFamily families of interfaces and
implementations.)
Beginning with version 4.8.0, objects implement the expected
interface; the BTree classes implement IBTree, the set
classes implement the appropriate set interface and so on.
BTree Family APIs¶
There are two families defined:
