Detailed Description

Used to transform a DDS into a w10n JSON metadata or w10n JSON data document.

The output is written to a local file whose name is passed as a parameter to the constructor.

Constructor & Destructor Documentation

FoDapJsonTransform::FoDapJsonTransform	(	libdap::DDS *	dds,
		BESDataHandlerInterface &	dhi,
		const std::string &	localfile
	)

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

Parameters

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

FoDapJsonTransform::~FoDapJsonTransform ( )

virtual

Destructor.

Cleans up any temporary data created during the transformation

Member Function Documentation

void FoDapJsonTransform::dump ( std::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 FoJson 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 FoDapJsonTransform::transform ( bool sendData )

virtual

Transforms each of the marked variables of the DataDDS to the JSON file.

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