ShapeReader
public class ShapeReader (Code)
	A demo of basic reading abilities exemplified by the shapefile access system. The demo opens a file, gets the feature type, reads the first ten features and outputs their contents to the standard output. author: aaime

Method Summary
public static void	main(String[] args)
public static ShapefileDataStore	openShapefile(URL shapeURL) This method will open a shapefile directly using the ShapefileDatastore. Please note this is "wrong" and limits your code to working with shapefiles for no reason.
public static DataStore	openShapefile2(URL url) You can use the DataStoreFinder to find additional kinds of data access (including shapefile). This will check the available jars on your class path, and return the first one that can work with the provided url.
public static DataStore	openShapefile3(URL url) You can use the DataStoreFinder to find additional kinds of data access (including shapefile).
public static URL	openURL() This method will prompt the user for a shapefile.

Method Detail

main
public static void main(String[] args)(Code)

openShapefile
public static ShapefileDataStore openShapefile(URL shapeURL) throws MalformedURLException(Code)
	This method will open a shapefile directly using the ShapefileDatastore. Please note this is "wrong" and limits your code to working with shapefiles for no reason. Look at openShapefile2 for a better example. See Also: ShapeReader.openShapefile2 Parameters: shapeURL - An URL for the shapefile the ShapefileDataStore which contains the shapefile data. throws: MalformedURLException -

openShapefile2

public static DataStore openShapefile2(URL url) throws IOException(Code)

You can use the DataStoreFinder to find additional kinds of data access (including shapefile).

This will check the available jars on your class path, and return the first one that can work with the provided url. This example goes through each data store, geoserver actually includes two datastores that can read shapefiles (one with indexing one without).

For your amusement we print out the parameters for the datastore used.

Parameters:
url - DataStore for the provided URL
throws:
IOException - If connection could not be made

openShapefile3
public static DataStore openShapefile3(URL url) throws IOException(Code)
	You can use the DataStoreFinder to find additional kinds of data access (including shapefile). This will check the available jars on your class path, and return the first one that can work with the provided url. Parameters: url - DataStore for the provided URL throws: IOException - If connection could not be made

openURL
public static URL openURL() throws MalformedURLException(Code)
	This method will prompt the user for a shapefile. This method will call System.exit() if the user presses cancel. url to selected shapefile. throws: MalformedURLException -
