SRU::Request - Factories for creating SRU request objects.

    use SRU::Request;
    my $request = SRU::Request->newFromURI( $uri );

SRU::Request allows you to create the appropriate SRU request object from a URI object. This allows you to pass in a URI and get back one of SRU::Request::Explain, SRU::Request::Scan or SRU::Request::SearchRetrieve depending on the type of URI that is passed in. See the docs for those classes for more information about what they contain.

newFromURI() is a factory method which you pass a complete SRU url. newFromURI() will return an appropriate object for the type of request being conducted:

* SRU::Request::Explain

* SRU::Request::Scan

* SRU::Request::SearchRetrieve

If the request is not formatted properly the call will return undef. The error encountered should be available in $SRU::Error.

    my $cgi = CGI->new();
    my $request = SRU::Request->newFromCGI( $cgi );

Used to generate <echoedExplainRequest>, <echoedSearchRetrieveRequest> and <echoedScanRequest> elements in the response.

Returns 'searchRetrieve', 'scan' or 'explain' depending on what type of object it is.
