Syntax

public class WKTFileReader

Remarks

The geometries in the file may be separated by any amount of whitespace and newlines.

Constructors

WKTFileReader(FileInfo, WKTReader)

Creates a new WKTFileReader given the file to read from and a WKTReader to use to parse the geometries.

Declaration

public WKTFileReader(FileInfo file, WKTReader wktReader)

Parameters

Type	Name	Description
FileInfo	file	the FileInfo to read from
WKTReader	wktReader	the geometry reader to use

WKTFileReader(Stream, WKTReader)

Creates a new WKTFileReader, given a Stream to read from.

Declaration

public WKTFileReader(Stream stream, WKTReader wktReader)

Parameters

Type	Name	Description
Stream	stream	The stream to read from
WKTReader	wktReader	The geometry reader to use

WKTFileReader(TextReader, WKTReader)

Creates a new WKTFileReader, given a TextReader to read with.

Declaration

public WKTFileReader(TextReader reader, WKTReader wktReader)

Parameters

Type	Name	Description
TextReader	reader	The stream reader of the file to read from
WKTReader	wktReader	The geometry reader to use

WKTFileReader(string, WKTReader)

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

Declaration

public WKTFileReader(string filename, WKTReader wktReader)

Parameters

Type	Name	Description
string	filename	The name of the file to read from
WKTReader	wktReader	The geometry reader to use

Properties

Limit

Gets/Sets the maximum number of geometries to read.

Declaration

public int Limit { get; set; }

Property Value

Type	Description
int

Offset

Gets/Sets the number of geometries to skip before reading.

Declaration

public int Offset { get; set; }

Property Value

Type	Description
int

StrictParsing

Gets/Sets allow ignoring WKT parse errors after at least one geometry has been read, to return a partial result.

Declaration

public bool StrictParsing { get; set; }

Property Value

Type	Description
bool

Methods

Read()

Reads a sequence of geometries.

Declaration

public IList<Geometry> Read()

Returns

Type	Description
IList<Geometry>	The list of geometries read

Remarks

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.

Exceptions

Type	Condition
IOException	Thrown if an I/O exception was encountered
ParseException	Thrown if an error occurred reading a geometry
