Detailed Description

Transformation object that converts an OPeNDAP DataDDS to a netcdf file.

This class transforms each variable of the DataDDS to a netcdf file. For more information on the transformation please refer to the OpeNDAP documents wiki.

Constructor & Destructor Documentation

FONcTransform::FONcTransform	(	DDS *	dds,
		BESDataHandlerInterface &	dhi,
		const string &	localfile,
		const string &	ncVersion = `"netcdf"`
	)

Build a FONcTransform object.

Constructor that creates transformation object from the specified DataDDS object to the specified file.

By default it builds a netcdf 3 file; pass "netcdf-4" to get a netcdf 4 file.

Note: added default value to fourth param to preserve the older API. 5/6/13 jhrg

Parameters

dds
dhi
localfile
netcdfVersion
dds	DataDDS object that contains the data structure, attributes and data
dhi	The data interface containing information about the current request
localfile	netcdf to create and write the information to

Exceptions

BESInternalError if dds provided is empty or not read, if the file is not specified or failed to create the netcdf file

Member Function Documentation

void FONcTransform::dump ( ostream & strm ) const

virtual

dumps information about this transformation object for debugging purposes

Displays the pointer value of this instance plus instance data, including all of the FONc objects converted from DAP objects that are to be sent to the netcdf file.

Parameters

strm	C++ i/o stream to dump the information to

Implements BESObj.

Here is the call graph for this function:

void FONcTransform::transform ( )

virtual

Transforms each of the variables of the DataDDS to the NetCDF file.

For each variable in the DataDDS write out that variable and its attributes to the netcdf file. Each OPeNDAP data type translates into a particular netcdf type. Also write out any global variables stored at the top level of the DataDDS.
