public class WKBHexFileReader
extends Object

Reads a sequence of Geometrys in WKBHex format from a text file. Each WKBHex geometry must be on a single line The geometries in the file may be separated by any amount of whitespace and newlines.

Constructor Detail

WKBHexFileReader

public WKBHexFileReader(File file,
                        WKBReader wkbReader)

Creates a new WKBHexFileReader given the File to read from and a WKTReader to use to parse the geometries.

Parameters:

file - the File to read from

wkbReader - the geometry reader to use

WKBHexFileReader

public WKBHexFileReader(String filename,
                        WKBReader wkbReader)

Creates a new WKBHexFileReader, given the name of the file to read from.

Parameters:

filename - the name of the file to read from

wkbReader - the geometry reader to use

WKBHexFileReader

public WKBHexFileReader(Reader reader,
                        WKBReader wkbReader)

Creates a new WKBHexFileReader, given a Reader to read from.

Parameters:

reader - the reader to read from

wkbReader - the geometry reader to use

Method Detail

setLimit

public void setLimit(int limit)

Sets the maximum number of geometries to read.

Parameters:

limit - the maximum number of geometries to read

setOffset

public void setOffset(int offset)

Sets the number of geometries to skip before storing.

Parameters:

offset - the number of geometries to skip

read

public List read()
          throws IOException,
                 ParseException

Reads a sequence of geometries. If an offset is specified, geometries read up to the offset count are skipped. If a limit is specified, no more than limit geometries are read.

Returns:

the list of geometries read

Throws:

IOException - if an I/O exception was encountered

ParseException - if an error occured reading a geometry
