Member Function Documentation

add_component()

template<typename T >

bool bm::Context::add_component ( std::shared_ptr< T >  ptr )

inline

Add a component to this Context. Each Context maintains a map T -> shared_ptr<T>, which maps a type (using typeid) to a shared pointer to an object of the same type. The pointer can be retrieved at a later time by using get_component().

get_component()

template<typename T >

std::shared_ptr<T> bm::Context::get_component ( )

inline

Retrieve the shared pointer to an object of type T previously added to the Context using add_component().

get_config_options()

ConfigOptionMap bm::Context::get_config_options ( ) const

private

Return string-to-string map of the target-specific options included in the input config JSON for this context.

get_deparser()

Deparser* bm::Context::get_deparser ( const std::string &  name )

inline

Get a raw, non-owning pointer to the Deparser object with P4 name name. Return a nullptr if there is no deparser with this name.

get_error_codes()

ErrorCodeMap bm::Context::get_error_codes ( ) const

private

Return a copy of the error codes map (a bi-directional map between an error code's integral value and its name / description).

get_extern_instance()

ExternSafeAccess bm::Context::get_extern_instance

(

const std::string &

name

)

Obtain a pointer to an extern instance, wrapped inside an ExternSafeAccess object. The wrapper holds a shared mutex, to make sure that accessing the extern is safe (in the case where a P4 swap occurs).

get_field_list()

FieldList* bm::Context::get_field_list ( const p4object_id_t  field_list_id )

inline

Get a raw, non-owning pointer to the FieldList object with id field_list_id

get_parser()

Parser* bm::Context::get_parser ( const std::string &  name )

inline

Get a raw, non-owning pointer to the Parser object with P4 name name. Return a nullptr if there is no parser with this name.

get_pipeline()

Pipeline* bm::Context::get_pipeline ( const std::string &  name )

inline

Get a raw, non-owning pointer to the Pipeline object with P4 name name. Return a nullptr if there is no pipeline with this name.
