Package org.deegree.coverage.raster.io Description

Defines the io operations for reading and writing rasters (not the data).

An implementation of data RasterIOProvider provides some Implementations of the RasterReader RasterWriter interface. The loading of such a provider is loaded using the ServiceLoading mechanism, default default deegree 3 io providers are provided.

A RasterIOProvider provide a RasterReader, which provides methods about the possible file types it can handle, but the loading of the actual data (the raster/coverage images) is done by supplying an implementation of a RasterDataReader, which provides methods to retrieve a datacontainer.

Both above mentioned implementations supply implementations of these RasterDataReaders. For example:

the org.deegree.coverage.io.imageio.IIORasterIOProvider provide the org.deegree.coverage.io.imageio.IIORasterReader (an implementation of the org.deegree.coverage.raster.io.RasterReader) which adds the possible file types of imageIO. It then uses org.deegree.coverage.io.imageio.IIORasterDataReader (an implementation of org.deegree.coverage.raster.io.RasterReader) to access the images/raster files.
