Detailed Description

template<class ENTITY>
class argos::CPositionalIndex< ENTITY >

A data structure that contains positional entities.

This interface defines the basic operations a data structure can do on positional entities. It is meant to provide methods to perform operations on entities within given ranges.

Member Function Documentation

◆ AddEntity()

template<class ENTITY >

virtual void argos::CPositionalIndex< ENTITY >::AddEntity ( ENTITY & c_entity )

pure virtual

Adds an entity to this index.

Parameters

c_entity The entity to add.

Implemented in argos::CAbstractSpaceHash< ENTITY >, and argos::CGrid< ENTITY >.

◆ Destroy()

template<class ENTITY >

virtual void argos::CPositionalIndex< ENTITY >::Destroy ( )

pure virtual

Undoes whatever was done by Init().

Implements argos::CBaseConfigurableResource.

Implemented in argos::CGrid< ENTITY >, argos::CGrid< argos::CLEDEntity >, argos::CGrid< argos::CTagEntity >, argos::CGrid< argos::CEmbodiedEntity >, argos::CGrid< argos::CRadioEntity >, argos::CGrid< argos::CDirectionalLEDEntity >, and argos::CGrid< argos::CRABEquippedEntity >.

◆ ForAllEntities()

template<class ENTITY >

virtual void argos::CPositionalIndex< ENTITY >::ForAllEntities ( COperation & c_operation )

pure virtual

Executes an operation on all the indexed entities.

Parameters

c_operation The operation to perform.

See also: COperation

Implemented in argos::CGrid< ENTITY >.

◆ ForEntitiesAlongRay()

template<class ENTITY >

virtual void argos::CPositionalIndex< ENTITY >::ForEntitiesAlongRay	(	const CRay3 &	c_ray,
		COperation &	c_operation,
		bool	b_stop_at_closest_match = `false`
	)

pure virtual

Executes an operation on all entities that intersect the given ray.

When the parameter b_stop_at_closest_matches is set to true, this method stops at the closest match. Depending on the actual index implementation, there may be multiple closest matches. In this case, the operation is executed on all of them.

Parameters

c_ray	The ray.
c_operation	The operation to perform.
b_stop_at_closest_matches	Stop the computation as soon as the first match is found.

Implemented in argos::CGrid< ENTITY >.

◆ ForEntitiesInBoxRange()

template<class ENTITY >

virtual void argos::CPositionalIndex< ENTITY >::ForEntitiesInBoxRange	(	const CVector3 &	c_center,
		const CVector3 &	c_half_size,
		COperation &	c_operation
	)

pure virtual

Executes an operation on all entities within the specified box range.

The box is axis-aligned.

Parameters

c_center	The box center.
c_half_size	The box half-size.
c_operation	The operation to perform.

See also: COperation

Implemented in argos::CGrid< ENTITY >.

◆ ForEntitiesInCircleRange()

template<class ENTITY >

virtual void argos::CPositionalIndex< ENTITY >::ForEntitiesInCircleRange	(	const CVector3 &	c_center,
		Real	f_radius,
		COperation &	c_operation

	)		const

pure virtual

Puts the entities located at the given point in the passed buffer.

Parameters

c_entities	The entity set to use as buffer.
c_position	The wanted point in the space.

Implemented in argos::CGrid< ENTITY >.

◆ Init()

template<class ENTITY >

virtual void argos::CPositionalIndex< ENTITY >::Init ( TConfigurationNode & t_tree )

pure virtual

Initializes the resource.

Parameters
