----------------------------------------
Summary: Logical namespace handling user-defined functions
Key: SYSTEMML-2232
URL: https://issues.apache.org/jira/browse/SYSTEMML-2232
Project: SystemML
Issue Type: Task
Reporter: Matthias Boehm
At script level functions might have logical namespace names such as
{{foo::bar()}}, where foo is the namespace name, and bar is the function name.
To handle namespace conflicts, SYSTEMML-631 internally replaced the logical
namespaces with filenames. For reasons such as improved statistics output and
the handling of namespace functions in the recently introduced {{eval}}
function (SYSTEMML-2077), it would be good to keep the logical namespace as
well.
This task aims to (1) extend the {{FunctionStatementBlock}} and
{{FunctionProgramBlock}} data structures to keep the logical namespace name,
(2) extend the parser and compiler accordingly, and (3) modify the statistics
maintenance to use the function key (i.e., concatenation of logical namespace
and function name) as the opcode.
