◆ list2DGrids()

bool mio::IOHandler::list2DGrids	(	const Date &	start,
		const Date &	end,
		std::map< Date, std::set< size_t > > &	list
	)

virtual

Return the list of grids within a given time period that could be read by the plugin, if requested.

This call should be implemented by all plugins reading grids, so the GridsManager can perform all kinds of advanced features with grids (computing a parameter from other ones, temporally interpolating, etc)

Parameters

[in]	start	the start of the time interval
[in]	end	the end of the interval
[out]	list	the list of grids. The first key is the date, then a set of parameters (from MeteoGrids::Parameters)

Returns: true if the list could be filled (even if empty), false if such as list can not be filled by the plugin (for example, it does not have the data before actually reading it)

Reimplemented from mio::IOInterface.

◆ operator=()

IOHandler & mio::IOHandler::operator= ( const IOHandler & source )

Assignement operator.
