virtual

It returns data set with observations of time series whose geometries satisfy a given spatial relation and times satisfy a given temporal relation.

Parameters

info	Information about the DataSource which the observations of a time series are from and the DataSet which contains the observations.
e	A given envelope.
r	A given spatial relation.
travType	The traverse type associated to the returned dataset.

Returns: The returned time series data set.

Note: The caller will take the ownership of the returned pointer.; It can throw an Exception when internal errors occur.

void te::st::STDataLoaderFromDS::getInfo	(	const TrajectoryDataSetInfo &	input,
		std::vector< TrajectoryDataSetInfo > &	output
	)

virtual

It returns the information about all trajectories that exist in a single DataSet.

The information about the DataSource and DataSet that contains trajectories is defined as a TrajectoryDataSetInfo (input parameter).

The information about each trajectory (its correct id) is returned as a TrajectoryDataSetInfo of the parameter output. These results can be used to create TrajectoryDataSetLayers.

Parameters

input	The information about the DataSource and DataSet that contains trajectories
output	The information about each trajectory (its correct id).

Note: It can throw an Exception when internal errors occur.

te::gm::Envelope te::st::STDataLoaderFromDS::getSpatialExtent ( const ObservationDataSetInfo & info )

virtual

It returns the temporal extent of the data set with observations of a coverage series.

Returns: The temporal extent of the observations of a coverage series.
