chrono::ChCheckpointReader Class Reference

Description

Reader for a block of checkpoint data written with a ChCheckpointWriter.

Every read checks the type of the next entry and throws a std::runtime_error on a mismatch or if the block has no more data, so that a checkpoint that does not match the system fails loudly.

Member Function Documentation

Read()

template<typename Derived >

void chrono::ChCheckpointReader::Read ( Eigen::PlainObjectBase< Derived > &  m )

inline

Read an Eigen matrix or vector.

A dynamic-size object is resized as needed; a fixed-size object must have the stored dimensions.

ReadIndexedBlocks()

void chrono::ChCheckpointReader::ReadIndexedBlocks	(	size_t	n,
		const std::function< void(size_t, ChCheckpointReader &)> &	load
	)

Read blocks written with ChCheckpointWriter::WriteIndexedBlocks, passing each one to the provided function.

Throws if a stored index is not in [0,n) or if the function does not consume its entire block.
