TimespanInequality

class timespantools.TimespanInequality(template=None)

Timespan inequality.

>>> import abjad
>>> template = 'timespan_2.start_offset < timespan_1.start_offset'
>>> inequality = abjad.TimespanInequality(template)
>>> inequality
TimespanInequality('timespan_2.start_offset < timespan_1.start_offset')

Methods

TimespanInequality.evaluate(timespan_1_start_offset, timespan_1_stop_offset, timespan_2_start_offset, timespan_2_stop_offset)

Evalutes inequality.

Returns true or false.

TimespanInequality.evaluate_offset_inequality(timespan_start, timespan_stop, offset)

Evalutes offset inequality.

Returns true or false.

Gets offset indices of inequality.

Todo

add example.

Returns nonnegative integer pair.

Special methods

(AbjadObject).__eq__(argument)

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

Returns true or false.

TimespanInequality.__format__(format_specification='')

Formats inequality.

>>> f(inequality)
abjad.TimespanInequality('timespan_2.start_offset < timespan_1.start_offset')

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.
