void libdap::DDS::transfer_attributes | ( | DAS * | das | ) | [virtual, inherited] |
This is the main method used to transfer attributes from a DAS object into a DDS. This uses the BaseType::transfer_attributes() method and the various implementations found here (in the constructors classes) and in handlers.
This method uses a deep copy to transfer the attributes, to it's safe to delete the source DAS object passed to this method once it's done.

BaseType * libdap::DDS::var | ( | const string & | n, |
BaseType::btp_stack * | s = 0 |
||
) | [inherited] |
Returns a pointer to the named variable. If the name contains one or more field separators then the function looks for a variable whose name matches exactly. If the name contains no field separators then the function looks first in the top level and then in all subsequent levels and returns the first occurrence found. In general, this function searches constructor types in the order in which they appear in the DDS, but there is no requirement that it do so.
n | The name of the variable to find. |
s | If given, this value-result parameter holds the path to the returned BaseType. Thus, this method can return the FQN for the variable n. |
