Constructor & Destructor Documentation

Meta()

Meta	(	uint	seq,
		uint	family
	)

Member Function Documentation

isPlausible()

bool isPlausible

(

)

const

Sanity check on the metadata header.

Remarks

Relevant to detect memory corruption or when accessing some arbitrary memory location, which may or may not actually hold a TestFrame. Based on the assumption that it is unlikely that any given memory location just happens to hold our marker word by accident.

Note

this is only the base level of verification, because in addition isValid verifies the checksum and isPristine additionally recomputes the data generation to see if it matches the Meta::distinction.
