Abstract Classes

QEvent

Abstract Q-event.

abstract class abjadext.nauert.qevents.QEvent(offset: Offset | int | float | tuple[int, int] = 0, index: int | None = None, attachments: Iterable | None = None)

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.
from_offset_pitches_attachments
index	The optional index, for sorting QEvents with identical offsets.
offset	The offset in milliseconds of the event.

---

Special methods

overridden __lt__(argument) → bool

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

overridden __repr__()

Gets repr.

---

Class & static methods

classmethod from_offset_pitches_attachments(offset, pitches, attachments) → QEvent

---

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: Offset | int | float | tuple[int, int] = 0, pitches: Iterable[int | float] | None = None, attachments: Iterable | None = None, index: int | None = None)

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) → bool

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.

overridden __hash__() → int

Hashes pitched q-event.

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

(QEvent).__lt__(argument) → bool

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

overridden __repr__()

Gets repr.

---

Class & static methods

classmethod (QEvent).from_offset_pitches_attachments(offset, pitches, attachments) → QEvent

---

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: Offset | int | float | tuple[int, int] = 0, attachments: Iterable | None = None, index: int | None = None)

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) → bool

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

overridden __hash__() → int

Hashes silent q-event.

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

(QEvent).__lt__(argument) → bool

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

(QEvent).__repr__()

Gets repr.

class abjadext.nauert.qevents.TerminalQEvent(offset: Offset | int | float | tuple[int, int] = 0)

Terminal q-event.

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

Carries no significance outside the context of a QEventSequence.
