                        int dimension)

Create a CoordinateWriter for outputting GML coordinates.

The use of dimension, z and useZ is based on your needs:

• dimension: is from your CoordinateReferenceSystem; it is the number of axis used by the coordinate
• useZ: is used to force the use of 3 dimensions (if needed the z value below will be used for 2D data)
• z: the dummy z value to use if the coordinate does not have one

Parameters:

numDecimals - Number of decimals to use (a speed vs accuracy trade off)

tupleDelim - delimiter to use between ordinates (usually ',')

coordDelim - delimiter to use between coordinates (usually ' ')

useZ - true if the provided zValue should be forced

z - Dummy z value to use if needed

dimension - Dimension of coordinates (usually 2 or 3)

Method Detail

getNumDecimals

public int getNumDecimals()

isDummyZEnabled

public boolean isDummyZEnabled()

setNamespaceAware

public void setNamespaceAware(boolean namespaceAware)

setPrefix

public void setPrefix(String prefix)

setNamespaceUri

public void setNamespaceUri(String namespaceUri)

writeCoordinates

public void writeCoordinates(Coordinate[] c,
                             ContentHandler output)
                      throws SAXException

Deprecated. use #writeCoordinates(CoordinateSequence, ContentHandler) instead

Write the provided list of coordinates out.

There are a range of constants that control exactly what is written:

• useDummyZ: if true dummyZ will be added to each coordiante
• namespaceAware: is true the prefix and namespaceUri will be used

Parameters:

c -

output -

Throws:

SAXException
