Detailed Description

Note
This class can now compute checksums for data that will be marshalled. jhrg 1/18/2012

Constructor & Destructor Documentation

libdap::XDRStreamMarshaller::XDRStreamMarshaller ( ostream &  out)

Build an instance of XDRStreamMarshaller. Bind the C++ stream out to this instance. If the checksum parameter is true, initialize a checksum buffer and enable the use of the reset_checksum() and get_checksum() methods.

Parameters
outWrite to this stream object.
checksumIf true, compute checksums. False by default
write_dataIf true, write data values. True by default

Member Function Documentation

void libdap::XDRStreamMarshaller::dump ( ostream &  strm) const
virtual

This method is implemented by all derived classes to dump their contents, in other words, any state they might have, private variables, etc...

The inline function below can be used to dump the contents of an OPeNDAOObj object. For example, the object Animal is derived from DapObj. A user could do the following:

Animal *a = new dog( "Sparky" ) ; cout << a << endl ;

And the dump method for dog could display the name passed into the constructor, the (this) pointer of the object, etc...

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