Attribute summary

callbacks Gets callbacks.
__eq__(expr) Is true when ID of expr equals ID of Abjad object.

__repr__() Gets interpreter representation of Abjad object.

Read-only properties

Expression.callbacks

Gets callbacks.

Returns tuple or none.

Special methods

(AbjadObject).__eq__(expr)

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

Returns true or false.

(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__(expr)

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

Returns true or false.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.
