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::FoDapJsonTransform ( libdap::DDS * dds )

Get the JSON encoding for a DDS.

Set up the JSON output transform object. This constructor builds an object that will build a JSON encoding for a DDS. This class can return both the entire DDS, including data, and a metadata-only response.

Note: The 'transform' method is used to build the response and a bool flag is passed to it to select data or metadata. However, if that flag is true and the DDS does not already contain data, the result is undefined.

Parameters

dds	DDS object

Exceptions

BESInternalError if the DDS* is null or if localfile is empty.

Member Function Documentation

◆ dump()

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.

◆ json_simple_type_array()

template<typename T>

void FoDapJsonTransform::json_simple_type_array	(	ostream *	strm,
		libdap::Array *	a,
		string	indent,
		bool	sendData )

Writes the json representation of the passed DAP Array of simple types. If the parameter "sendData" evaluates to true then data will also be sent.

Definition at line 112 of file FoDapJsonTransform.cc.

◆ json_simple_type_array_worker()

template<typename T>

unsigned int FoDapJsonTransform::json_simple_type_array_worker	(	ostream *	strm,
		T *	values,
		unsigned int	indx,
		vector< unsigned int > *	shape,
		unsigned int	currentDim )

@TODO Handle String and URL Arrays including backslash escaping double quotes in values.
