Detailed Description

BESTransmitter class named "geotiff" that transmits an OPeNDAP data object as a geotiff file.

The JPEG2000Transmitter transforms an OPeNDAP DataDDS object into a geotiff file and streams the new (temporary) geotiff file back to the client.

Constructor & Destructor Documentation

◆ JPEG2000Transmitter()

JPEG2000Transmitter::JPEG2000Transmitter ( )

Construct the JPEG2000Transmitter, adding it with name geotiff to be able to transmit a data response.

The transmitter is created to add the ability to return OPeNDAP data objects (DataDDS) as a geotiff file.

The OPeNDAP data object is written to a geotiff file locally in a temporary directory specified by the BES configuration parameter JPEG2000.Tempdir. If this variable is not found or is not set then it defaults to the macro definition JPEG2000_TEMP_DIR.

Note
The mapping from a 'returnAs' of "geotiff" to this code is made in the JPEG2000Module class.

Member Function Documentation

◆ dump()

void BESTransmitter::dump ( std::ostream &  strm) const
virtualinherited

dumps information about this object

Displays the pointer value of this instance along with the names of register transmit methods

Parameters
strmC++ i/o stream to dump the information to

Implements BESObj.

Definition at line 132 of file BESTransmitter.cc.

◆ send_data_as_jp2()

void JPEG2000Transmitter::send_data_as_jp2 ( BESResponseObject obj,
BESDataHandlerInterface dhi 
)
static

The static method registered to transmit OPeNDAP data objects as a netcdf file.

This function takes the OPeNDAP DataDDS object, reads in the data (can be used with any data handler), transforms the data into a netcdf file, and streams back that netcdf file back to the requester using the stream specified in the BESDataHandlerInterface.

Parameters
objThe BESResponseObject containing the OPeNDAP DataDDS object
dhiBESDataHandlerInterface containing information about the request and response
Exceptions
BESInternalErrorif the response is not an OPeNDAP DataDDS or if there are any problems reading the data, writing to a netcdf file, or streaming the netcdf file
