qevents¶

Abstract Classes

QEvent

Abstract Q-event.

abstract class abjadext.nauert.qevents.QEvent(offset=0, index=None, attachments=None)[source]¶

Abstract Q-event.

Represents an attack point to be quantized.

All QEvents possess a rational offset in milliseconds, and an optional index for disambiguating events which fall on the same offset in a QGrid.

Attributes Summary

`__lt__`	Is true when epxr is a q-event with offset greater than that of this q-event.
`__repr__`	Gets repr.
`attachments`	The attachments of the QEvent.
`index`	The optional index, for sorting QEvents with identical offsets.
`offset`	The offset in milliseconds of the event.

Special methods

overridden __lt__(argument)[source]¶

Is true when epxr is a q-event with offset greater than that of this q-event. Otherwise false.

Return type:: bool

overridden __repr__()[source]¶: Gets repr.

Read-only properties

attachments¶: The attachments of the QEvent.

index¶: The optional index, for sorting QEvents with identical offsets.

offset¶: The offset in milliseconds of the event.

Classes

`PitchedQEvent`	Pitched q-event.
`SilentQEvent`	Silent q-event.
`TerminalQEvent`	Terminal q-event.

class abjadext.nauert.qevents.PitchedQEvent(offset=0, pitches=None, attachments=None, index=None)[source]¶

Pitched q-event.

Indicates the onset of a period of pitched material in a q-event sequence.

>>> pitches = [0, 1, 4]
>>> nauert.PitchedQEvent(1000, pitches)
PitchedQEvent(offset=Offset((1000, 1)), pitches=(NamedPitch("c'"), NamedPitch("cs'"), NamedPitch("e'")), index=None, attachments=())

Attributes Summary

`__eq__`	Is true when argument is a pitched q-event with offset, pitches, attachments and index equal to those of this pitched q-event.
`__hash__`	Hashes pitched q-event.
`__repr__`	Gets repr.
`attachments`	Attachments of pitched q-event.
`pitches`	Pitches of pitched q-event.

Special methods

overridden __eq__(argument)[source]¶

Is true when argument is a pitched q-event with offset, pitches, attachments and index equal to those of this pitched q-event. Otherwise false.

Return type:: bool

overridden __hash__()[source]¶

Hashes pitched q-event.

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

Return type:: int

(QEvent).__lt__(argument)¶

Is true when epxr is a q-event with offset greater than that of this q-event. Otherwise false.

Return type:: bool

overridden __repr__()[source]¶: Gets repr.

Read-only properties

overridden attachments¶: Attachments of pitched q-event.

(QEvent).index¶: The optional index, for sorting QEvents with identical offsets.

(QEvent).offset¶: The offset in milliseconds of the event.

pitches¶: Pitches of pitched q-event.

class abjadext.nauert.qevents.SilentQEvent(offset=0, attachments=None, index=None)[source]¶

Silent q-event.

>>> q_event = nauert.SilentQEvent(1000)
>>> q_event
SilentQEvent(offset=Offset((1000, 1)), index=None, attachments=())

Attributes Summary

`__eq__`	Is true when argument is a silent q-event with offset, attachments and index equal to those of this silent q-event.
`__hash__`	Hashes silent q-event.
`attachments`	Gets attachments of silent q-event.

Special methods

overridden __eq__(argument)[source]¶

Is true when argument is a silent q-event with offset, attachments and index equal to those of this silent q-event. Otherwise false.

Return type:: bool

overridden __hash__()[source]¶

Hashes silent q-event.

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

Return type:: int

(QEvent).__lt__(argument)¶

Is true when epxr is a q-event with offset greater than that of this q-event. Otherwise false.

Return type:: bool

(QEvent).__repr__()¶: Gets repr.

Read-only properties

overridden attachments¶: Gets attachments of silent q-event.

(QEvent).index¶: The optional index, for sorting QEvents with identical offsets.

(QEvent).offset¶: The offset in milliseconds of the event.

class abjadext.nauert.qevents.TerminalQEvent(offset=0)[source]¶

Terminal q-event.

>>> nauert.TerminalQEvent(1000)
TerminalQEvent(offset=Offset((1000, 1)), index=None, attachments=())

Carries no significance outside the context of a QEventSequence.

Attributes Summary

`__eq__`	Is true when argument is a terminal q-event with offset equal to that of this terminal q-event.
`__hash__`	Hashes terminal q-event.

Special methods

overridden __eq__(argument)[source]¶

Is true when argument is a terminal q-event with offset equal to that of this terminal q-event. Otherwise false.

Return type:: bool

overridden __hash__()[source]¶

Hashes terminal q-event.

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

Return type:: int

(QEvent).__lt__(argument)¶

Is true when epxr is a q-event with offset greater than that of this q-event. Otherwise false.

Return type:: bool

(QEvent).__repr__()¶: Gets repr.

Read-only properties

(QEvent).attachments¶: The attachments of the QEvent.

(QEvent).index¶: The optional index, for sorting QEvents with identical offsets.

(QEvent).offset¶: The offset in milliseconds of the event.
