The filter program receives a data request from the dispatch script. It receives its operating parameters from the command line, like any UNIX command, and it returns its output to standard output, which the httpd server packages up into a reply to the client.
This class contains some common functions for the filter programs used to make up the DODS data servers. The filter programs do not have to be called by a CGI program, but that is the normal mechanism by which they are invoked.
We need to rethink the ancillary file/directory stuff. I don't think it's ever been used...

Here is the call graph for this function:
DODSFilter::DODSFilter | ( | int | argc, | |
char * | argv[] | |||
) | throw (Error) |
Create an instance of DODSFilter using the command line arguments passed by the CGI (or other) program. The default constructor is private; this and the copy constructor (which is just the default copy constructor) are the only way to create an instance of DODSFilter.
These are the valid options:
-o
response
Specifies the type of response desired. The response is a string and must be one of DAS
, DDS
, DataDDS
or Version
. Note that Version
returns version information in the body of the response and is useful for debugging, et cetera. Each response returns version information in an HTTP header for internal use by a client.
-c
-e
expression
-v
cgi-versioncgi-version
. This is a way for the caller to set version information passed back to the client either as the response to a version request of in the response headers.
-d
ancdir
-f
ancfile
-r
cache directory
-t
timeout
-l
timeLast-Modified
time from an If-Modified-Since condition GET request. It is given in seconds since the start of the Unix epoch (Midnight, 1 Jan 1970).

This method perform a simple check on the file named by the dataset given when the DODSFilter instance was created. If the dataset is not a filter, this method returns the current time. Servers which provide access to non-file-based data should subclass DODSFilter and supply a more suitable version of this method.

Set the CGI/Server version number. Servers use this when answering requests for version information. The version `number' should include both the name of the server (e.g., ff_dods
) as well as the version number. Since this information is typically divined by configure, it's up to the executable to poke the correct value in using this method.
Note that the -v switch that this class understands is deprecated since it is usually called by Perl code. It makes more sense to have the actual C++ software set the version string.
