◆ setPropertyValue()

void Mantid::DataHandling::Load::setPropertyValue	(	const std::string &	name,
		const std::string &	value
	)

overridevirtual

Override setPropertyValue.

Override setPropertyValue to catch if filename is being set, as this may mean a change of concrete loader.

If it's any other property, just forward the call.

Parameters

name	The name of the property
value	The value of the property as a string

Reimplemented from Mantid::API::Algorithm.

◆ setUpLoader()

void Mantid::DataHandling::Load::setUpLoader	(	const API::IAlgorithm_sptr &	loader,
		const double	startProgress = `-1.0`,
		const double	endProgress = `-1.0`,
		const bool	logging = `true`
	)		const

private

Set the loader option for use as a Child Algorithm.

Parameters

loader	:: Concrete loader
startProgress	:: The start progress fraction
endProgress	:: The end progress fraction
logging,:	If true, enable logging
