mpi_array.indexing.IndexingExtent¶

class mpi_array.indexing.IndexingExtent(slice=None, start=None, stop=None, struct=None)[source]¶

Methods

`__init__`([slice, start, stop, struct])	Construct, must specify either `slice` or both of `start` and `stop`.
`calc_intersection`(other)	Returns the indexing extent which is the intersection of this extent with the `other` extent.
`calc_intersection_split`(other)	Returns `(leftovers, intersection)` pair, where `intersection` is the `IndexingExtent` object (possibly `None`) indicating the intersection of this (`self`) extent with the `other` extent and `leftovers` is a list of `IndexingExtent` objects indicating regions of `self` which do not intersect with the `other` extent.
`create_struct_dtype_from_ndim`(ndim)	Creates a `numpy.dtype` structure for holding start and stop indices.
`create_struct_instance`(ndim)	Creates a struct instance with `numpy.dtype` `self.struct_dtype_dict[ndim]`.
`get_struct_dtype`(ndim)
`get_struct_dtype_from_ndim`(ndim)
`split`(a, index)	Split this extent into two extents by cutting along axis `a` at index `index`.
`to_slice`()	Returns “`tuple` of `slice`” equivalent of this indexing extent.
`to_tuple`()	Convert this instance to a `tuple` which can be passed to constructor (or used as a `dict` key).

Attributes

`START`
`START_STR`
`STOP`
`STOP_STR`	Indexing bounds for a single tile of domain decomposition.
`ndim`	Dimension of indexing.
`shape`	Sequence of `int` indicating the shape of this extent (including halo).
`start`	Sequence of `int` indicating the per-axis start indices of this extent (including halo).
`stop`	Sequence of `int` indicating the per-axis stop indices of this extent (including halo).
