All Implemented Interfaces:

public class IlvRasterCADRGReader
extends IlvRasterAbstractReader

CADRG Raster reader. This reader is able to generate images for IlvCADRGCoverage set using addCADRGCoverage(IlvCADRGCoverage). Example of use:

 // read the CADRG table of contents
  IlvCADRGTocReader tocReader = new IlvCADRGTocReader(fileName);
 // retrieve the cadrg coverages.
  IlvCADRGCoverage coverages[]= tocReader.getCoverages();
 // create the CADRG Raster reader.
  IlvRasterCADRGReader cadrgReader = new IlvRasterCADRGReader();
 // add all coverages into the raster reader.
  for(int iCov=0;iCov<coverages.length;iCov++) {
    cadrgReader.addCADRGCoverage(coverages[iCov]);
  }

JViews 7.0

Constructor Detail

IlvRasterCADRGReader

public IlvRasterCADRGReader()

Creates a new IlvRasterCADRGReader.

IlvRasterCADRGReader

public IlvRasterCADRGReader(IlvInputStream stream)
                     throws IlvReadFileException

Creates a new IlvRasterCADRGReader from previously saved information in the input stream.

Parameters:

stream - Stream being read.

Throws:

IlvReadFileException

Method Detail

getCoordinateSystem

public IlvCoordinateSystem getCoordinateSystem()

Returns a WGS84 system.

Returns:

The coordinate system, or null if the coordinate system is unknown.

See Also:

IlvMapFeatureIterator.getCoordinateSystem()

getInternalTransformation

public IlvMathTransform getInternalTransformation(int imageIndex)

Return the projection associated with the raster stored at the given index.

Specified by:

getInternalTransformation in class IlvRasterAbstractReader

Parameters:

imageIndex - The index of the raster.

Returns:

The projection that corresponds to the raster stored at the given index.

See Also:

IlvRasterAbstractReader.getInternalTransformation(int)

getProperties

public IlvFeatureAttributeProperty getProperties(int imageIndex)

Returns the feature properties to be associated with the image.

Specified by:

getProperties in class IlvRasterAbstractReader

Parameters:

imageIndex - The index of the image.

Returns:

The properties to be associated with the image.

See Also:

IlvRasterAbstractReader.getProperties(int)

addCADRGCoverage

public void addCADRGCoverage(IlvCADRGCoverage cov)

Adds a CADRG Coverage to the list of images being managed.

Parameters:

cov - Coverage to manage as a set of images.

reload

public void reload(IlvThreadMonitoringData monitorInfo)

Given the state of the reader (number of images read, coverage zone,...), the purpose of this method is to recreate all images from the original source. Note : this method should not rely on the list of IlvRasterProperties of the reader as they might not be saved when the theme only is saved.

Overrides:

reload in class IlvRasterAbstractReader

Parameters:

monitorInfo - Used to update task progress.

See Also:

IlvRasterAbstractReader.reload(ilog.views.maps.raster.datasource.IlvThreadMonitoringData)

getUpperLeftCorner

public IlvCoordinate getUpperLeftCorner(IlvCADRGFrame frame,
                                        int subFrameIndex)

Computes the upper left corner of a sub frame.

Parameters:

frame - Frame containing the subframe

subFrameIndex - sub frame index (0-35)

Returns:

the coordinate in the coverage system of upper left corner.

getLowerRightCorner

public IlvCoordinate getLowerRightCorner(IlvCADRGFrame frame,
                                         int subFrameIndex)

Computes the upper lower right of a sub frame.

Parameters:

frame - Frame containing the subframe

subFrameIndex - sub frame index (0-35)

Returns:

the coordinate in the coverage system of lower right corner.

addCADRGFrame

public void addCADRGFrame(IlvCADRGFrame frame)

Adds a single CADRG Frame to the list of images being managed.

Parameters:

frame - Frame to add to the set of managed images.

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the attributes of a persistent object.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvRasterAbstractReader

Parameters:

stream - The output stream.

Throws:

IOException - thrown when an exception occurs during the write operation for this object.
