Constructor Detail

WKTWriter2

public WKTWriter2()

Creates a new WKTWriter with default settings

WKTWriter2

public WKTWriter2(int outputDimension)

Creates a writer that writes Geometrys with the given output dimension (2 or 3). If the specified output dimension is 3, the Z value of coordinates will be written if it is present (i.e. if it is not Double.NaN).

Parameters:

outputDimension - the coordinate dimension to output (2 or 3)

Method Detail

toPoint

public static String toPoint(Coordinate p0)

Generates the WKT for a POINT specified by a Coordinate.

Parameters:

p0 - the point coordinate

Returns:

the WKT

toLineString

public static String toLineString(CoordinateSequence seq)

Generates the WKT for a LINESTRING specified by a CoordinateSequence.

Parameters:

seq - the sequence to write

Returns:

the WKT string

toLineString

public static String toLineString(Coordinate p0,
                                  Coordinate p1)

Generates the WKT for a LINESTRING specified by two Coordinates.

Parameters:

p0 - the first coordinate

p1 - the second coordinate

Returns:

the WKT

stringOfChar

public static String stringOfChar(char ch,
                                  int count)

Returns a String of repeated characters.

Parameters:

ch - the character to repeat

count - the number of times to repeat the character

Returns:

a String of characters

setFormatted

public void setFormatted(boolean isFormatted)

Sets whether the output will be formatted.

Overrides:

setFormatted in class WKTWriter

Parameters:

isFormatted - true if the output is to be formatted

setMaxCoordinatesPerLine

public void setMaxCoordinatesPerLine(int coordsPerLine)

Sets the maximum number of coordinates per line written in formatted output. If the provided coordinate number is <= 0, coordinates will be written all on one line.

Overrides:

setMaxCoordinatesPerLine in class WKTWriter

Parameters:

coordsPerLine - the number of coordinates per line to output.

setTab

public void setTab(int size)

Sets the tab size to use for indenting.

Overrides:

setTab in class WKTWriter

Parameters:

size - the number of spaces to use as the tab string

Throws:

IllegalArgumentException - if the size is non-positive

write

public String write(Geometry geometry)

Converts a Geometry to its Well-known Text representation.

Overrides:

write in class WKTWriter

Parameters:

geometry - a Geometry to process

Returns:

a string (see the OpenGIS Simple Features Specification)

write

public void write(Geometry geometry,
                  Writer writer)
           throws IOException

Converts a Geometry to its Well-known Text representation.

Overrides:

write in class WKTWriter

Parameters:

geometry - a Geometry to process

Throws:

IOException

writeFormatted

public String writeFormatted(Geometry geometry)

Same as write, but with newlines and spaces to make the well-known text more readable.

Overrides:

writeFormatted in class WKTWriter

Parameters:

geometry - a Geometry to process

Returns:

a string (see the OpenGIS Simple Features Specification), with newlines and spaces

writeFormatted

public void writeFormatted(Geometry geometry,
                           Writer writer)
                    throws IOException

Same as write, but with newlines and spaces to make the well-known text more readable.

Overrides:

writeFormatted in class WKTWriter

Parameters:

geometry - a Geometry to process

Throws:

IOException
