Attributes Summary

__str__ String representation of vector.
from_selection Makes vector from selection.

Special methods

(TypedCounter).__add__(argument)

Adds typed counter to argument.

Returns new typed counter.

(TypedCounter).__and__(argument)

Logical AND of typed counter and argument.

Returns new typed counter.

(TypedCollection).__contains__(item)

Is true when typed collection contains item.

Returns true or false.

(TypedCounter).__delitem__(item)

Deletes item from typed counter.

Returns none.

(TypedCollection).__eq__(argument)

Is true when argument is a typed collection with items that compare equal to those of this typed collection.

Returns true or false.

(AbjadObject).__format__(format_specification='')

Formats Abjad object.

Set format_specification to '' or 'storage'. Interprets '' equal to 'storage'.

Returns string.

(TypedCounter).__getitem__(argument)

Gets item or slice identified by argument.

Returns item or slice.

(TypedCollection).__hash__()

Hashes typed collection.

Redefined in tandem with __eq__.

(TypedCollection).__iter__()

Iterates typed collection.

Returns generator.

(TypedCollection).__len__()

Gets length of typed collection.

Returns nonnegative integer.

(TypedCounter).__or__(argument)

Logical OR of typed counter and argument.

Returns new typed counter.

(TypedCounter).__radd__(argument)

Adds argument to typed counter.

Returns new typed counter.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.

(TypedCounter).__setitem__(item, value)

Sets typed counter item to value.

Returns none.

__str__()

String representation of vector.

Returns string.

(TypedCounter).__sub__(argument)

Subtracts argument from typed counter.

Returns new typed counter.


Methods

(TypedCounter).clear()

Clears typed counter.

Returns none.

(TypedCounter).copy()

Copies typed counter.

Returns new typed counter.

(TypedCounter).elements()

Elements in typed counter.

abstract from_selection(selection, item_class=None)

Makes vector from selection.

Returns vector.

(Mapping).get(k[, d]) → D[k] if k in D, else d. d defaults to None.
(TypedCounter).items()

Items in typed counter.

Returns tuple.

(TypedCounter).keys()

Iterates keys in typed counter.

(TypedCounter).most_common(n=None)

Please document.

(MutableMapping).pop(k[, d]) → v, remove specified key and return the corresponding value.

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

(MutableMapping).popitem() → (k, v), remove and return some (key, value) pair

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

(MutableMapping).setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D
(TypedCounter).subtract(iterable=None, **keywords)

Subtracts iterable from typed counter.

(TypedCounter).update(iterable=None, **keywords)

Updates typed counter with iterable.

(TypedCounter).values()

Iterates values in typed counter.

(TypedCounter).viewitems()

Please document.

(TypedCounter).viewkeys()

Please document.

(TypedCounter).viewvalues()

Please document.


Read-only properties

(TypedCollection).item_class

Gets item class of collection.

Collection coerces items according to item_class.

Returns class.
