Edge(std::shared_ptr<detail::CUDAEnvironmentDirectedGraphBuffers> _directed_graph, cudaStream_t _stream, id_t _source_vertex_id, id_t _dest_vertex_id)
void setSourceVertexID(id_t source_vertex_id)

Set the source vertex’s id for the current edge

Parameters:

source_vertex_id – The value to set the current edge’s source vertex id

void setDestinationVertexID(id_t dest_vertex_id)

Set the destination vertex’s id for the current edge

Parameters:

dest_vertex_id – The value to set the current edge’s destination vertex id

void setSourceDestinationVertexID(id_t source_vertex_id, id_t dest_vertex_id)

Set the source and destination vertices’ ids for the current edge

Parameters:

  • source_vertex_id – The value to set the current edge’s source vertex id

  • dest_vertex_id – The value to set the current edge’s destination vertex id

template<typename T>
void setProperty(const std::string &property_name, T property_value)

Set the value of the specified property of the current edge

Parameters:

  • property_name – The name of the property to set

  • property_value – The value to set the current edge’s property

Template Parameters:

T – The type of the property

Throws:

exception::InvalidArgument – If property_name does not refer to a valid edge property

void setProperty(const std::string &property_name, flamegpu::size_type element_index, T property_value)
template<typename T, flamegpu::size_type N>
void setProperty(const std::string &property_name, const std::array<T, N> &property_value)
id_t getSourceVertexID() const

Returns the source vertex’s id for the current edge

id_t getDestinationVertexID() const

Returns the destination vertex’s id for the current edge

template<typename T>
T getProperty(const std::string &property_name) const

Returns the value of the specified property of the current edge

Parameters:

property_name – The name of the property to set

Template Parameters:

T – The type of the property

Throws:

  • exception::InvalidArgument – If property_name does not refer to a valid edge property

  • exception::InvalidGraphProperty – If a edge property with the matching name and type does not exist
