lib.theory.base.ProjectionBasisCollection

class lib.theory.base.ProjectionBasisCollection(items=None)

Bases: cosmopipe.lib.utils.BaseOrderedCollection

Class representing a collection of projection basis.

Note

When adding a basis equal to another already in the collection, the latter will be replaced by the former. Insertion order is conserved.

Initialize BaseOrderedCollection.

Parameters

items (list, object, BaseOrderedCollection) – List of elements to add to the collection. If not list, interpreted as single element. If BaseOrderedCollection instance, update __dict__.

Methods

clear	Empty collection.
concatenate	Concatenate input collections.
copy	Return shallow copy of self.
deepcopy
extend	Extend collection with other.
from_state	Instantiate and initalize class with state dictionary.
get_by_proj	Try to fetch the projection basis that matches the input ProjectionName, by priority order:
index	Return index of item in collection.
is_mpi_broadcast
is_mpi_gathered
is_mpi_root
is_mpi_scattered
load	Load class in numpy binary format from disk.
load_auto	If different formats are possible, this method should between them based on file name extension.
log_critical
log_debug
log_error
log_info
log_warning
modes	Return list of ProjectionBasis.mode.
reorder	Reorder collection following index list indices.
save	Save class to disk.
save_auto	If different formats are possible, this method should between them based on file name extension.
select	Return new collection, after selection of items whose attribute match input values.
set	Set item in collection.
spaces	Return list of ProjectionBasis.space.
unique	Return list of unique attribute key of collection items.

Attributes

logger
mpiattrs	MPI attributes
mpicomm
mpiroot
mpistate

__add__(other)

Addition of two collections is defined as concatenation.

clear()

Empty collection.

classmethod concatenate(*others)

Concatenate input collections. Unique items only are kept.

copy()

Return shallow copy of self.

extend(other)

Extend collection with other. Unique items only are kept.

classmethod from_state(state, mpiroot=0, mpicomm=None)

Instantiate and initalize class with state dictionary.

get_by_proj(*args, **kwargs)

Try to fetch the projection basis that matches the input ProjectionName, by priority order:

• same ProjectionBasis.name

• same ProjectionBasis.space

• same ProjectionBasis.mode

• same ProjectionBasis.wa_order

Stops as soon as a single match is found. Raises an IndexError if no or several matches are found.

Parameters

• args (list) – Arguments for ProjectionName.

• kwargs (dict) – Arguments for ProjectionName.

Returns

basis

Return type

ProjectionBasis

index(item)

Return index of item in collection.

classmethod load(filename, mpiroot=0, mpicomm=None)

Load class in numpy binary format from disk. If the loaded state contains __class__ and that exists in cls._registry, return instance of cls._registry[__class__] (instead of cls).

load_auto(*args, **kwargs)

If different formats are possible, this method should between them based on file name extension.

modes()

Return list of ProjectionBasis.mode.

property mpiattrs

MPI attributes

reorder(indices)

Reorder collection following index list indices.

save(filename)

Save class to disk.

save_auto(*args, **kwargs)

If different formats are possible, this method should between them based on file name extension.

select(*args, **kwargs)

Return new collection, after selection of items whose attribute match input values:

collection.select(name1=value1,name2=value2)

returns collection of items whose attributes name1 and name2` are value1, value2, respectively. Also:

collection.select(dict(name1=value1,name2=value2),dict(name2=value3))

returns collection of items whose attributes name1 and name2` are value1, value2, respectively or attribute name2 is value3.

set(item)

Set item in collection. If already in collection (following criteria defined in item.__eq__), replace this stored item by the input one. Else, append item to collection.

spaces()

Return list of ProjectionBasis.space.

unique(key)

Return list of unique attribute key of collection items.
