chrono::ChCheckpointWriter Class Reference

Description

Writer for a block of checkpoint data.

A physics item, FEA element or FEA node writes its internal state (data not stored in the system state vectors) to a writer; the checkpoint database stores the resulting block in its own format. The same data must be read back, in the same order, with a ChCheckpointReader. See the developer manual on the physics item lifecycle.

WriteIndexedBlocks()

void chrono::ChCheckpointWriter::WriteIndexedBlocks	(	size_t	n,
		const std::function< void(size_t, ChCheckpointWriter &)> &	save
	)

Write, for each index in [0,n), the block produced by the provided function, tagged with that index.

Empty blocks are skipped. Read back with ChCheckpointReader::ReadIndexedBlocks.
