Constructor & Destructor Documentation

RBSCMEvaluationSerialization() [1/3]

libMesh::RBDataSerialization::RBSCMEvaluationSerialization::RBSCMEvaluationSerialization

(

RBSCMEvaluation &

rb_eval

)

Initialize a new buffer using the structure from the Cap'n'Proto schema described in rb_data.capnp.

RBSCMEvaluationSerialization() [2/3]

libMesh::RBDataSerialization::RBSCMEvaluationSerialization::RBSCMEvaluationSerialization ( RBSCMEvaluationSerialization &&  )

default

Special functions.

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

RBSCMEvaluationSerialization() [3/3]

libMesh::RBDataSerialization::RBSCMEvaluationSerialization::RBSCMEvaluationSerialization ( const RBSCMEvaluationSerialization &  )

default

~RBSCMEvaluationSerialization()

write_to_file()

void libMesh::RBDataSerialization::RBSCMEvaluationSerialization::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.
