            ParSequence

Known Subclasses:

ParRootSequence

Global distributed sequence

The local value of a ParSequence object is a slice of the input sequence, which is constructed such that the concatenation of the local values of all processors equals the input sequence while making the number of elements on each processor as equal as possible.

Instance Methods

any

__getitem__(self, item)
Returns: the element referred to by the index, if it is in the local subset

__init__(self, full_sequence)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

int

totalLength(self)
Returns: the sum of the lengths of the local values

Inherited from ParValue: __add__, __call__, __div__, __divmod__, __eq__, __ge__, __getattr__, __gt__, __le__, __len__, __lt__, __mod__, __mul__, __ne__, __neg__, __nonzero__, __pow__, __repr__, __str__, __sub__, accumulate, alltrue, anytrue, broadcast, fullExchange, get, getattr, map, put, reduce

Inherited from object: __delattr__, __getattribute__, __hash__, __new__, __reduce__, __reduce_ex__, __setattr__

Method Details

getitem(self, item)
(Indexing operator)

Parameters:

item (int or ParIndex) - an index into the total sequence

Returns: any

the element referred to by the index, if it is in the local subset

Raises:

IndexError - if the index refers to an item on another processor

Overrides: ParValue.__getitem__

init(self, full_sequence)
(Constructor)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:

full_sequence (arbitrary sequence object) - the full sequence, equal to the concatenation of the local values of all processors

Overrides: object.__init__

totalLength(self)

Returns: int: the sum of the lengths of the local values
