TransientRBEvaluationSerialization() [2/3]

libMesh::RBDataSerialization::TransientRBEvaluationSerialization::TransientRBEvaluationSerialization ( TransientRBEvaluationSerialization &&  )

default

Special functions.

• This class contains a reference, so it can't be default copy/move-assigned.
• The destructor is defaulted out of line.

TransientRBEvaluationSerialization() [3/3]

~TransientRBEvaluationSerialization()

write_to_file()

void libMesh::RBDataSerialization::TransientRBEvaluationSerialization::write_to_file	(	const std::string &	path,
		bool	use_packing = false
	)

Write the Cap'n'Proto buffer to disk.

If use_packing is true, the file is written using the "packed" scheme, which can reduce the filesize on disk.
