Detailed Description

Base class for all objects in the arranger that have a length.

The BoundedObject class is the base class for all objects that have a length, such as regions, MIDI notes, etc. It provides common functionality and properties shared by all these objects, such as start and end positions, and methods to resize and check if the object is hit by a position or range.

BoundedObject inherits from ArrangerObject and extends it with length-related functionality.

◆ end_position_setter_validated()

void zrythm::structure::arrangement::BoundedObject::end_position_setter_validated	(	const dsp::Position &	pos,
		dsp::TicksPerFrame	ticks_per_frame )

inline

The setter is for use in e.g.

the digital meters whereas the set_pos func is used during arranger actions.

Definition at line 57 of file bounded_object.h.

◆ get_end_position()

auto zrythm::structure::arrangement::BoundedObject::get_end_position ( ) const

inline

Getter.

Definition at line 46 of file bounded_object.h.

◆ get_length_in_frames()

auto zrythm::structure::arrangement::BoundedObject::get_length_in_frames ( ) const

inline

Returns the length in frames.

(End Position - start Position).

Definition at line 85 of file bounded_object.h.

◆ get_length_in_ticks()

auto zrythm::structure::arrangement::BoundedObject::get_length_in_ticks ( ) const

inline

Returns the length in ticks.

(End Position - start Position).

◆ is_hit() [1/2]

bool zrythm::structure::arrangement::BoundedObject::is_hit	(	const dsp::Position &	pos,
		bool	object_end_pos_inclusive = false ) const

inline

Returns whether the object is hit by the given position (local position if non-timeline object).

Parameters

pos	Position to check.
obj_end_pos_inclusive	Whether end_pos_ is considered as part of the object. This is probably always false.

Definition at line 146 of file bounded_object.h.

◆ is_hit() [2/2]

bool zrythm::structure::arrangement::BoundedObject::is_hit	(	const signed_frame_t	frames,
		bool	object_end_pos_inclusive = false ) const

inline

Returns whether the given object is hit by the given range.

Parameters

start	Start position.
end	End position.
range_start_inclusive	Whether pos_ == `start` is allowed. Can't imagine a case where this would be false, but kept an option just in case.

ZrythmException on failure.

◆ end_pos_

utils::QObjectUniquePtr<PositionProxy> zrythm::structure::arrangement::BoundedObject::end_pos_

End Position, if the object has one.

This is exclusive of the material, i.e., the data at this position is not counted (for audio regions at least, TODO check for others).
