This module demonstrate the usage of the various classes defined in list_clone

class sage.structure.list_clone_demo.IncreasingArray[source]#

Bases: ClonableArray

A small extension class for testing ClonableArray.

check()[source]#

Check that self is increasing.

EXAMPLES:

sage: from sage.structure.list_clone_demo import IncreasingArrays
sage: IncreasingArrays()([1,2,3]) # indirect doctest
[1, 2, 3]
sage: IncreasingArrays()([3,2,1]) # indirect doctest
Traceback (most recent call last):
...
ValueError: array is not increasing

>>> from sage.all import *
>>> from sage.structure.list_clone_demo import IncreasingArrays
>>> IncreasingArrays()([Integer(1),Integer(2),Integer(3)]) # indirect doctest
[1, 2, 3]
>>> IncreasingArrays()([Integer(3),Integer(2),Integer(1)]) # indirect doctest
Traceback (most recent call last):
...
ValueError: array is not increasing

>>> IncreasingIntArrays()([Integer(1),Integer(2),Integer(3)]) # indirect doctest
[1, 2, 3]
>>> IncreasingIntArrays()([Integer(3),Integer(2),Integer(1)]) # indirect doctest
Traceback (most recent call last):
...

check()[source]#

Check that self is increasing

EXAMPLES:

sage: from sage.structure.list_clone_demo import IncreasingLists
sage: IncreasingLists()([1,2,3]) # indirect doctest
[1, 2, 3]
sage: IncreasingLists()([3,2,1]) # indirect doctest
Traceback (most recent call last):
...
ValueError: array is not increasing

>>> from sage.all import *
>>> from sage.structure.list_clone_demo import IncreasingLists
>>> IncreasingLists()([Integer(1),Integer(2),Integer(3)]) # indirect doctest

Element[source]#

alias of IncreasingList

class sage.structure.list_clone_demo.SortedList[source]#

Bases: NormalizedClonableList

A small extension class for testing NormalizedClonableList.

check()[source]#

Check that self is strictly increasing

EXAMPLES:

sage: from sage.structure.list_clone_demo import SortedList, SortedLists
sage: SortedLists()([1,2,3]) # indirect doctest
[1, 2, 3]
sage: SortedLists()([3,2,2]) # indirect doctest
Traceback (most recent call last):
...
ValueError: list is not strictly increasing

>>> from sage.all import *
>>> from sage.structure.list_clone_demo import SortedList, SortedLists
>>> SortedLists()([Integer(1),Integer(2),Integer(3)]) # indirect doctest
[1, 2, 3]
>>> SortedLists()([Integer(3),Integer(2),Integer(2)]) # indirect doctest
Traceback (most recent call last):
...
ValueError: list is not strictly increasing
normalize()[source]#

Normalize self

Sort the list stored in self.

EXAMPLES:

sage: from sage.structure.list_clone_demo import SortedList, SortedLists
sage: l = SortedList(SortedLists(), [3,1,2], False, False)
sage: l         # indirect doctest
[1, 2, 3]
sage: l[1] = 5; l
[1, 5, 3]
sage: l.normalize(); l
[1, 3, 5]

>>> from sage.all import *
>>> from sage.structure.list_clone_demo import SortedList, SortedLists
>>> l = SortedList(SortedLists(), [Integer(3),Integer(1),Integer(2)], False, False)
>>> l         # indirect doctest
[1, 2, 3]
>>> l[Integer(1)] = Integer(5); l
[1, 5, 3]
>>> l.normalize(); l
[1, 3, 5]
