Detailed Description

template<typename T_Type>
struct codi::PrimalBinaryTapeReader< T_Type >

Reads and restores a binary file for a Primal tape.

The reader uses the "filename".dat file to restore the statements and the "filename"IO.dat to restore the inputs and outputs of the tape.

The format of the read "filename".dat file is as follows:

lhsIdentifier(Identifier) primalValue(Real) nPassiveValues(Config::ArgumentSize)
numberOfActiveArguments(Config::ArgumentSize) (rhsIdentifiers(Identifier) ... [repeats numberOfArguments times])
(passiveValues(Real) ... [repeats nPassiveValues times]) numberOfConstantArguments(Config::ArgumentSize)
(constantValues(Real) ... [repeats numberOfConstantArguments times]) evalHandleKey(EvalHandle)

The primal values are read from the "filename"Primals.dat file.

The EvalHandles are created in the "filename".hpp file, which should be included for the read process.

See codi::TapeReaderInterface for a general description on how to use primal value tape readers.

Template Parameters

T_Type

The CoDiPack type of the tape that is to be restored.
