Detailed Description

Manages rules and ids for different types of geometry in the graph generator.

See also: GeometryFilterMode for more info about each mode of this struct; HIT_FLAG for info about the different geometry flags; CheckGeometryID for using this struct to check the results of an intersection

◆ DetermineFilterMode()

void HF::GraphGenerator::GeometryFlagMap::DetermineFilterMode	(	const std::vector< int > &	walkable,
		const std::vector< int > &	obstacle
	)

inlineprivate

Set the filter mode of this GeometryFlagMap based on the input types.

Parameters

walkable	Array of walkable geometry IDs
obstacle	Array of obstacle geometry IDs

If the walkable array is empty, then set the mode to obstacles only. If the obstacle and the walkable arrays are empty set the mode to none If both obstacle and walkable arrays are specified, set this mode to obstacles and floors.

Postcondition: Sets the filter type for this hit_dict to the appropriate value for the number of elements in walkable and obstacle

Here is the caller graph for this function:

◆ HasKey()

bool HF::GraphGenerator::GeometryFlagMap::HasKey ( int id ) const

inline

Check if this id exists in the dictionary.

Parameters

id	ID to check for

Returns: True if the ID exists, false otherwise.

Referenced by operator[]().

Here is the caller graph for this function:

◆ operator[]()

HIT_FLAG HF::GraphGenerator::GeometryFlagMap::operator[] ( int id ) const

inline

Get the flag of the geometry in this hit dictionary.

Parameters

id	ID of geometry to get the hitflag of

Returns: The flag assigned to id in SetGeometryIDs or HIT_FLAG::NO_FLAG if no flag was ever assigned to id

Remarks: Unlike the standard square brackets operator of std::unordered_map, this gaurantees no memory is allocated. Note that this can't be used to assign keys.

Here is the call graph for this function:

◆ Set()

void HF::GraphGenerator::GeometryFlagMap::Set	(	int	id,
		HIT_FLAG	flag
	)

inline

Set the value of a key in the internal dictionary.

Parameters

id	ID to set as

Postcondition: Next call to [] for this object with id will return flag. If id already has been assigned a flag, the value will be updated to flag.

Here is the caller graph for this function:

◆ SetGeometryIds()

void HF::GraphGenerator::GeometryFlagMap::SetGeometryIds	(	const std::vector< int > &	obstacle_geometry,
		const std::vector< int > &	walkable_geometry
	)

inline

Set geometry ids as being walkable or obstacles.

Parameters

obstacle_geometry	IDs of meshes to set as obstacles
walkable_geometry	IDs of meshes to set as walkable

Postcondition: 1) The filter mode for this hit_dict will be set to the appropriate value for the inputs; 2) All geometry in obstacle_geometry will return HIT_FLAG::OBSTACLES when calling operator [] and all geometry in walkable_geometry will return HIT_FLAG::FLOORS when calling operator[]
