Package uk.ac.rdg.resc.edal.dataset

Code for reading data from underlying storage (e.g. disk, databases or remote locations).

Interface Summary

Interface	Description
ContinuousDomainDataset
Dataset	Provides access to data and metadata held in underlying storage, e.g. on disk, in a database or on a remote server.
DataSource
DiscreteFeatureReader<F extends DiscreteFeature<?,?>>	Defines an interface for reading DiscreteFeatures.
DomainMapper.DomainMapperEntry<P>	Maps a point in the source grid to corresponding points in the target grid.
DomainMapper.Scanline<P>	Holds all the DomainMapperEntries corresponding with a certain j index
FeatureIndexer	A class representing a spatial indexer for features.
GridDataSource	Low-level interface to multidimensional grids, used by DataReadingStrategy.
HZTDataSource	A DataSource which reads data from a domain where the horizontal layers are based on an unstructured mesh, and the vertical / time dimensions are discrete.

Class Summary

Class	Description
AbstractContinuousDomainDataset	Partial implementation of a Dataset with a continuous domain which performs spatial indexing of features.
AbstractDataset
DatasetFactory	A factory for Dataset objects.
DiscreteLayeredDataset<DS extends DataSource,VM extends DiscreteLayeredVariableMetadata>	A partial implementation of an HorizontallyDiscreteDataset based on a 4D dataset where the z- and t-dimensions are discrete axes.
Domain1DMapper	This is an implementation of a DomainMapper which maps 2D indices from a source grid onto a single integer in the target domain.
Domain2DMapper	This is an implementation of a DomainMapper which maps 2D indices from a source grid onto a pair of integers (as int[]) in the target domain.
Domain2DMapper.Domain2DMapperCacheKey
DomainMapper<T>	Maps real-world points to i and j indices of corresponding points within the source data.
FakeTrajectoryDatasetFactory
FakeTrajectoryDatasetFactory.FakeTrajectoryDataset
FeatureIndexer.FeatureBounds	A class representing the spatial bounds of a feature with a single point.
GriddedDataset	A partial implementation of a Dataset based on a 4D grid, using a GridDataSource and a DataReadingStrategy.
HorizontallyDiscreteDataset<DS extends DataSource>	A partial implementation of a 4-dimensional Dataset which handles the use of plugins to generate values.
HorizontalMesh4dDataset	Partial implementation of a Dataset where the horizontal layers are based on an unstructured mesh, and the vertical / time dimensions are discrete.
HZTDataSource.MeshCoordinates3D	Class representing a set of 3 integer co-ordinates.
InMemoryMeshDataSource	A simple in-memory implementation of an HZTDataSource.
PointDataset<F extends DiscreteFeature<?,?>>	An AbstractContinuousDomainDataset whose map features are PointFeatures.
PRTreeFeatureIndexer	This uses a PRTree to index features spatially.
TrajectoryDataset	A Dataset which contains only TrajectoryFeatures.
