Member Function Documentation

bool delphos::BZ::ExpectedTimeToTextFile ( const char * exptime_file ) const

virtual

Writes the expected times in given file.

Parameters

exptime_file The name of the file in which the expected times are written.

bool delphos::BZ::RelaxedSolToTextFile	(	const char *	relsol_file,
		const char *	stocks_file = `""`
	)

virtual

Writes the relaxed solution in given text files.

Parameters

relsol_file	The file in which the relaxed solution for the blocks is written.
stocks_file	The file in which the relaxed solution for the stocks is written.

bool delphos::BZ::SetExpectedTime ( const string & column )

virtual

Sets the expected times from a block model attribute with given name.

Parameters

column The column attribute name from which the expected times are extracted.

void delphos::BZ::SetLogFile ( const string & name )

virtual
