Class WKBHexFileReader

Hierarchy: Object , WKBHexFileReader

public class WKBHexFileReader

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.

Authors:: Martin Davis

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 - file the File to read from; wkbReader - wkbReader the geometry reader to use

public WKBHexFileReader(String filename, WKBReader wkbReader)

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

Parameters:: filename - filename the name of the file to read from; wkbReader - wkbReader the geometry reader to use

public WKBHexFileReader(Reader reader, WKBReader wkbReader)

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

Parameters:: reader - reader the reader to read from; wkbReader - wkbReader the geometry reader to use

public void setLimit(int limit)

Sets the maximum number of geometries to read.

Parameters:: limit - limit the maximum number of geometries to read

public void setOffset(int offset)

Sets the number of geometries to skip before storing.

Parameters:: offset - offset the number of geometries to skip

public List read()

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 - IOException if an I/O exception was encountered; ParseException - ParseException if an error occurred reading a geometry
