Format classes are required to expose a constructor with no arguments,
|
|
a getFileExtension() and a sendResponse(opts, callback) method.
|
|
|
|
The ``opts`` parameter contains:
|
|
|
|
sink Output stream to send the reponse to
|
|
sql SQL query requested by the user
|
|
skipfields Comma separate list of fields to skip from output
|
|
really only needed with "SELECT *" queries
|
|
gn Name of the geometry column (for formats requiring one)
|
|
dp Number of decimal points of precision for geometries (if used)
|
|
database Name of the database to connect to
|
|
user_id Identifier of the user
|
|
filename Name to use for attachment disposition
|
|
|
|
The ``callback`` parameter is a function that is invoked when the
|
|
format object finished with sending the result to the sink.
|
|
If an error occurs the callback is invoked with an Error argument.
