Detailed Description

The Detachable class is a special case of the Entity base class.

Detachable allows the Entity's reference Frame to be changed arbitrarily by the user.

Constructor & Destructor Documentation

◆ Detachable() [1/2]

dart::dynamics::Detachable::Detachable	(	Frame *	_refFrame,
		bool	_quiet
	)

explicit

Constructor.

◆ Detachable() [2/2]

dart::dynamics::Detachable::Detachable ( )

protected

Constructor for inheriting classes, so they do not need to fill in the arguments.

Member Function Documentation

◆ addObserver()

void dart::common::Subject::addObserver ( Observer * _observer ) const

protectedinherited

Add an Observer to the list of Observers.

◆ changeParentFrame()

void dart::dynamics::Entity::changeParentFrame ( Frame * _newParentFrame )

protectedvirtualinherited

Used by derived classes to change their parent frames.

Reimplemented in dart::dynamics::Frame.

◆ descendsFrom()

bool dart::dynamics::Entity::descendsFrom ( const Frame * _someFrame ) const

inherited

Returns true if and only if this Entity is itself (i.e.

this == _someFrame) or depends on (i.e. kinematically descends from) _someFrame.

If _someFrame is nullptr, this returns true in order to accommodate BodyNodes which always have a nullptr BodyNode as the parent of a root BodyNode.

◆ dirtyAcceleration()

void dart::dynamics::Entity::dirtyAcceleration ( )

virtualinherited

Notify the acceleration of this Entity that its parent Frame's acceleration is needed.

Reimplemented in dart::dynamics::PointMassNotifier, dart::dynamics::Frame, and dart::dynamics::BodyNode.

◆ dirtyTransform()

void dart::dynamics::Entity::dirtyTransform ( )

virtualinherited

Notify the transformation update of this Entity that its parent Frame's pose is needed.

Reimplemented in dart::dynamics::PointMassNotifier, dart::dynamics::Frame, and dart::dynamics::BodyNode.

◆ dirtyVelocity()

void dart::dynamics::Entity::dirtyVelocity ( )

virtualinherited

Notify the velocity update of this Entity that its parent Frame's velocity is needed.

Reimplemented in dart::dynamics::PointMassNotifier, dart::dynamics::Frame, and dart::dynamics::BodyNode.

◆ getName()

virtual const std::string& dart::dynamics::Entity::getName ( ) const

pure virtualinherited

Return the name of this Entity.

Implemented in dart::dynamics::WorldFrame, dart::dynamics::SimpleFrame, dart::dynamics::PointMassNotifier, and dart::dynamics::BodyNode.

◆ getParentFrame() [1/2]

Frame * dart::dynamics::Entity::getParentFrame ( )

inherited

Get the parent (reference) frame of this Entity.

◆ getParentFrame() [2/2]

const Frame * dart::dynamics::Entity::getParentFrame ( ) const

inherited

Get the parent (reference) frame of this Entity.

◆ isFrame()

bool dart::dynamics::Entity::isFrame ( ) const

inherited

True iff this Entity is also a Frame.

◆ isQuiet()

bool dart::dynamics::Entity::isQuiet ( ) const

inherited

Returns true if this Entity is set to be quiet.

A quiet entity is unknown to its parent Frame. It will not be tracked by its parent; it will not receive notifications from its parent, and it will not be rendered. The advantage to a quiet Entity is that it has less overhead when constructing and deconstructing, which makes it more suitable for temporary objects.

◆ needsAccelerationUpdate()

bool dart::dynamics::Entity::needsAccelerationUpdate ( ) const

inherited

Returns true iff an acceleration update is needed for this Entity.

◆ needsTransformUpdate()

bool dart::dynamics::Entity::needsTransformUpdate ( ) const

inherited

Returns true iff a transform update is needed for this Entity.

◆ needsVelocityUpdate()

bool dart::dynamics::Entity::needsVelocityUpdate ( ) const

inherited

Returns true iff a velocity update is needed for this Entity.

◆ notifyAccelerationUpdate()

void dart::dynamics::Entity::notifyAccelerationUpdate ( )

virtualinherited

Notify the acceleration of this Entity that its parent Frame's acceleration is needed.

◆ notifyTransformUpdate()

void dart::dynamics::Entity::notifyTransformUpdate ( )

virtualinherited

Notify the transformation update of this Entity that its parent Frame's pose is needed.

◆ notifyVelocityUpdate()

void dart::dynamics::Entity::notifyVelocityUpdate ( )

virtualinherited

Notify the velocity update of this Entity that its parent Frame's velocity is needed.

◆ removeObserver()

void dart::common::Subject::removeObserver ( Observer * _observer ) const

protectedinherited

Remove an Observer from the list of Observers.

◆ sendDestructionNotification()

void dart::common::Subject::sendDestructionNotification ( ) const

protectedinherited

Send a destruction notification to all Observers.

This will cause all Observers to behave as if this Subject has been permanently deleted, so it should only be called when that behavior is desired.

◆ setName()

virtual const std::string& dart::dynamics::Entity::setName ( const std::string & _name )

pure virtualinherited

Set name.

Some implementations of Entity may make alterations to the name that gets passed in. The final name that this entity will use gets passed back in the return of this function.

Implemented in dart::dynamics::WorldFrame, dart::dynamics::SimpleFrame, dart::dynamics::PointMassNotifier, and dart::dynamics::BodyNode.

◆ setParentFrame()

void dart::dynamics::Detachable::setParentFrame ( Frame * _newParentFrame )

virtual

Allows the user to change the parent Frame of this Entity.
