org.geotools.data.coverage.grid
Class AbstractGridFormat

java.lang.Object
  org.geotools.data.coverage.grid.AbstractGridFormat

All Implemented Interfaces:: org.opengis.coverage.grid.Format

Direct Known Subclasses:: ArcGridFormat, GeoTiffFormat, GTopo30Format, UnknownFormat, WorldImageFormat

public abstract class AbstractGridFormat
extends java.lang.Object
implements org.opengis.coverage.grid.Format

AbstractGridFormat is a convenience class so subclasses only need to populate a Map class and set the read and write parameter fields. For example the ArcGridFormat has the following method which sets up all the required information: private void setInfo(){ HashMap info=new HashMap(); info.put("name", "ArcGrid"); info.put("description", "Arc Grid Coverage Format"); info.put("vendor", "Geotools"); info.put("docURL", "http://gdal.velocet.ca/projects/aigrid/index.html"); info.put("version", "1.0"); mInfo=info; readParameters=new GeneralParameterDescriptor[2]; readParameters[0]=ArcGridOperationParameter.getGRASSReadParam(); readParameters[0]=ArcGridOperationParameter.getCompressReadParam(); writeParameters=new GeneralParameterDescriptor[2]; writeParameters[0]=ArcGridOperationParameter.getGRASSWriteParam(); writeParameters[0]=ArcGridOperationParameter.getCompressWriteParam(); }

Field Detail

mInfo

protected java.util.Map mInfo

The Map object is used by the information methods(such as getName()) as a data source. The keys in the Map object (for the associated method) are as follows: getName() key = "name" value type=String getDescription() key = "description" value type=String getVendor() key = "vendor" value type=String getDocURL() key = "docURL" value type=String getVersion() key = "version" value type=String Naturally, any methods that are overridden need not have an entry in the Map

readParameters

protected org.opengis.parameter.ParameterValueGroup readParameters

writeParameters

protected org.opengis.parameter.ParameterValueGroup writeParameters

CRSAuthorityfactoriesMap

protected static java.util.Map CRSAuthorityfactoriesMap

Synchronized map of created CRS Authorities. Since creating a CRS Authority Factory is an heavy duty we store them there and we share them between all gridformats for all threads.
