dolmen.builtins 0.3.1

dolmen.builtins 提供了一组表示常用Python内置函数的接口。它的目的是使组件架构可以使用最基本的对象，并定义类型以便方便地扩展它们。

>>> from zope.interface import verify
>>> from dolmen.builtins import interfaces as base

>>> macduff = "Tis' a very nice string."
>>> base.IString.providedBy(macduff)
True

>>> macbeth = u"Aye, indeed my friend."
>>> base.IUnicode.providedBy(macbeth)
True

>>> is_usurper = True
>>> base.IBoolean.providedBy(is_usurper)
True

>>> crown = 1
>>> base.INumeric.providedBy(crown)
True

>>> king = 0.1
>>> base.INumeric.providedBy(king)
True

>>> opposants = 1L
>>> base.INumeric.providedBy(opposants)
True

更复杂类型在其接口中定义了更多信息。可迭代的和类似文件类就是这种情况。

>>> murderers = ('MacBeth', 'Lady MacBeth')
>>> base.ITuple.providedBy(murderers)
True

>>> victims = ['Banco', 'Duncan']
>>> base.IList.providedBy(victims)
True

>>> thanes = {"Glamis": "MacBeth", "Fife": "MacDuff"}
>>> base.IDict.providedBy(thanes)
True

>>> base.IIterable.providedBy(victims)
True
>>> base.IIterable.providedBy(murderers)
True
>>> base.IIterable.providedBy(thanes)
True

>>> verify.verifyObject(base.IDict, thanes)
True

>>> base.IFile.implementedBy(file)
True
>>> verify.verifyClass(base.IFile, file)
True
