Member Function Documentation

execute() [1/4]

FindFace::Code nfd::tools::nfdc::FindFace::execute	(	const FaceQueryFilter &	filter,
		bool	allowMulti = false
	)

Find face by FaceQueryFilter.

Precondition

execute has not been invoked

Definition at line 69 of file face-helpers.cpp.

execute() [2/4]

FindFace::Code nfd::tools::nfdc::FindFace::execute	(	const FaceUri &	faceUri,
		bool	allowMulti = false
	)

Find face by FaceUri.

Precondition

execute has not been invoked

Definition at line 41 of file face-helpers.cpp.

execute() [3/4]

FindFace::Code nfd::tools::nfdc::FindFace::execute	(	const std::any &	faceIdOrUri,
		bool	allowMulti = false
	)

Find face by FaceId or FaceUri.

Parameters

faceIdOrUri	either a FaceId (uint64_t) or a FaceUri
allowMulti	effective only if faceIdOrUri contains a FaceUri

Exceptions

ndn::bad_any_cast

faceIdOrUri is neither uint64_t nor FaceUri
