Revision history for Perl extension Net::Z3950::PQF.

0.04 Fri Oct 5 13:13:20 BST 2007

• Add new toSimpleServer() method to Net::Z3950::PQF::Node, returning the compiled query as a nested set of structures identical to those produced by the SimpleServer module and passed as the {RPN} argument into the search handler.
• Add new test-suite script, t/3-simpleserver.t, to test the translation of compiled queries into SimpleServer format.

0.03 Wed Apr 27 11:51:28 BST 2005

• Net::Z3950::PQF::TermNode and Net::Z3950::PQF::BooleanNode are now subclasses of Net::Z3950::PQF::BooleanNode as documented. Test script "t/1-node.t" now tests subclass relationships.
• Support for Rset nodes. Test script "t/1-node.t" now tests Rset nodes.
• Support for parsing @set. Test script "t/2-parser.t" now tests @set queries.
• Handle multi-word terms enclosed in {curly brackets}. Test script "t/2-parser.t" tests this.
• Representation of Term nodes has changed due to new private base-class shared with Rset nodes. NOTE THAT THIS IS A BACKWARDS INCOMPATIBLE CHANGE. Code that used to inspect $termNode->{term} should now use $termNode->{value}

• Support for creating and rendering ProxNode.
• Support for parsing @prox.
• Support for parsing @term.
