            _offsets

Implements the segmentlist offset book-keeping in the segmentlistdict class. Not intended for use outside of the segmentlistdict class.

Instance Methods

delitem(args)
(Index deletion operator)*

source code

del x[y]

Overrides: dict.__delitem__: (inherited documentation)

init(self, parent)
(Constructor)

source code

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

Returns: new empty dictionary
Overrides: object.__init__: (inherited documentation)

new(cls, parent)
Static Method

source code

Returns: a new object with type S, a subtype of T
Overrides: object.__new__: (inherited documentation)

reduce(self)

source code

helper for pickle

Overrides: object.__reduce__: (inherited documentation)

setitem(self, key, value)
(Index assignment operator)

source code

Set an offset. If the new offset is identical to the current offset this is a no-op, otherwise the corresponding segmentlist object is shifted.

Overrides: dict.__setitem__

clear(self)

source code

Remove the offsets from all segmentlists.

Returns: None
Overrides: dict.clear

fromkeys(*args)

source code

v defaults to None.

Returns: New dict with keys from S and values equal to v
Overrides: dict.fromkeys: (inherited documentation)

pop(*args)

source code

If key is not found, d is returned if given, otherwise KeyError is raised

Returns: v, remove specified key and return the corresponding value
Overrides: dict.pop: (inherited documentation)

popitem(*args)

source code

2-tuple; but raise KeyError if D is empty.

Returns: (k, v), remove and return some (key, value) pair as a
Overrides: dict.popitem: (inherited documentation)

update(self, d)

source code

From a dictionary of offsets, apply each offset to the corresponding segmentlist. NOTE: it is acceptable for the offset dictionary to contain entries for which there is no matching segmentlist; no error will be raised, but the offset will be ignored. This simplifies the case of updating several segmentlistdict objects from a common offset dictionary, when one or more of the segmentlistdicts contains only a subset of the keys.

Returns: None
Overrides: dict.update
