CodeCompiler.java

AST
The Python grammar
was changed to
include SIM, SQL,
Prolog, and ASP
statements.
Visitor

Runtime

PyTuple.java
jSIMParser
There is no
jSIMParser to parse
SIM statements like
jSQLParser for SQL
but I hope one will be
built as a project.
SIMHelper.java
SIMHelper produces
appropriate SPARQL
statements for the
SIM statements
which are sent to
SPARQLDoer.
------------
jSQLParser parses
SQL statements from
PyTuple and produces
an AST that can be
visited.

jSQLParser
parseSIM()
parseSIM parses SIM
statements from
PyTuple and produces
and passes AS
information to
SIMHelper.
The Tuple entry in
CodeCompiler was
modified to deal
with putting SIM,
SQL, Prolog, and
ASP information
and expressions on
the runtime stack
and to assure that a
new instance of
PyTuple is created
after the
expressions are
evaluated.
SQLVisitor visits the
jSQLParser AST and
produces appropriate
SPARQL statements
for the SQL
statements which are
sent to SPARQLDoer.
