Checks the payload info and makes sure we are using appropriate files. This assumes that the lis is positioned at the start and subsequently positions the lis just past the first line. So if we need to position the lis elsewhere, the caller needs to do that manually after this call.

Parameters:

lis - The line bytes stream

pvName - The PV name

type - Enum ArchDBRTypes

Throws:

IOException -
