Method Detail

getFormatName

public java.lang.String getFormatName()

Specified by:

getFormatName in interface ShapeIO

Returns:

the format name

write

protected void write(java.io.Writer output,
                     java.text.NumberFormat nf,
                     double... coords)

Description copied from interface: ShapeWriter

Write a shape to the output writer

Specified by:

write in interface ShapeWriter

Throws:

java.io.IOException

writeDistance

void writeDistance(java.io.Writer output,
                   java.text.NumberFormat nf,
                   double dist,
                   boolean isGeo,
                   java.lang.String distProperty,
                   java.lang.String distUnitsProperty)
            throws java.io.IOException

Helper method to encode a distance property (with optional unit).

The distance unit is only encoded when isGeo is true, and it is converted to km.

The distance unit is encoded within a properties object.

Parameters:

output - The writer.

nf - The number format.

dist - The distance value to encode.

isGeo - The flag determining

distProperty - The distance property name.

distUnitsProperty - The distance unit property name.

Throws:

java.io.IOException

toString

public java.lang.String toString(Shape shape)

Description copied from interface: ShapeWriter

Write a shape to String

Specified by:

toString in interface ShapeWriter
