DurationSpecifier¶

class abjadext.rmakers.DurationSpecifier.DurationSpecifier(*, decrease_monotonic=True, forbid_meter_rewriting=None, forbidden_duration=None, rewrite_meter=None, rewrite_rest_filled=None, spell_metrically=None)¶

Duration specifier.

Attributes Summary

`__format__`	Formats duration specifier.
`__repr__`	Gets interpreter representation.
`decrease_monotonic`	Is true when all durations should be spelled as a tied series of monotonically decreasing values.
`forbid_meter_rewriting`	Is true when meter rewriting is forbidden.
`forbidden_duration`	Gets forbidden written duration.
`rewrite_meter`	Is true when all output divisions should rewrite meter.
`rewrite_rest_filled`	Is true when rhythm-maker rewrites rest-filled divisions.
`spell_metrically`	Is true when durations should spell according to approximate common practice understandings of meter.

Special methods

(AbjadValueObject).__copy__(*arguments)¶

Copies Abjad value object.

Returns new Abjad value object.

(AbjadValueObject).__eq__(argument)¶

Is true when all initialization values of Abjad value object equal the initialization values of argument.

Returns true or false.

__format__(format_specification='')¶

Formats duration specifier.

>>> specifier = abjadext.rmakers.DurationSpecifier()
>>> abjad.f(specifier)
abjadext.rmakers.DurationSpecifier(
    decrease_monotonic=True,
    )

Return type:	`str`

(AbjadValueObject).__hash__()¶

Hashes Abjad value object.

Returns integer.

__repr__()¶

Gets interpreter representation.

>>> abjadext.rmakers.DurationSpecifier()
DurationSpecifier(decrease_monotonic=True)

Return type:	`str`

Read-only properties

decrease_monotonic¶

Is true when all durations should be spelled as a tied series of monotonically decreasing values.

>>> specifier = abjadext.rmakers.DurationSpecifier()
>>> specifier.decrease_monotonic
True

Return type:	`Optional`[`bool`]

forbid_meter_rewriting¶

Is true when meter rewriting is forbidden.

>>> specifier = abjadext.rmakers.DurationSpecifier()
>>> specifier.forbid_meter_rewriting is None
True

Return type:	`Optional`[`bool`]

forbidden_duration¶

Gets forbidden written duration.

>>> specifier = abjadext.rmakers.DurationSpecifier()
>>> specifier.forbidden_duration is None
True

Return type:	`Optional`[`Duration`]

rewrite_meter¶

Is true when all output divisions should rewrite meter.

>>> specifier = abjadext.rmakers.DurationSpecifier()
>>> specifier.rewrite_meter is None
True

Return type:	`Optional`[`bool`]

rewrite_rest_filled¶

Is true when rhythm-maker rewrites rest-filled divisions.

>>> specifier = abjadext.rmakers.DurationSpecifier()
>>> specifier.rewrite_rest_filled is None
True

Return type:	`Optional`[`bool`]

spell_metrically¶

Is true when durations should spell according to approximate common practice understandings of meter.

>>> specifier = abjadext.rmakers.DurationSpecifier()
>>> specifier.spell_metrically is None
True

Spells unassignable durations like 5/16 and 9/4 metrically when set to 'unassignable'. Leaves other durations unchanged.

Return type:	`Union`[`bool`, `str`, `None`]
