Special methods

abstract ContextManager.__enter__()

Enters context manager.

(AbjadObject).__eq__(argument)

Is true when ID of argument equals ID of Abjad object. Otherwise false.

Returns true or false.

abstract ContextManager.__exit__(exc_type, exc_value, traceback)

Exits context manager.

(AbjadObject).__format__(format_specification='')

Formats Abjad object.

Set format_specification to ‘’ or ‘storage’. Interprets ‘’ equal to ‘storage’.

Returns string.

(AbjadObject).__hash__()

Hashes Abjad object.

Required to be explicitly redefined on Python 3 if __eq__ changes.

Returns integer.

(AbjadObject).__ne__(argument)

Is true when Abjad object does not equal argument. Otherwise false.

Returns true or false.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.
