NOOP

Code with this flag makes no calculations, but rather returns a constant value. This flag is given to function and method variants that return a default value depending on the type of argument(s). When variants with this flag are resolved at parse time, a call-with-type-errors warning is raised (assuming this warning is enabled).

RT_NOOP

Code with this flag makes no calculations, but rather returns a constant value. This flag is given to function and method variants that return a default value depending on the type of argument(s). When variants with this flag are resolved at parse time, a call-with-type-errors warning is raised (assuming this warning is enabled), unless PO_REQUIRE_TYPES or PO_STRICT_ARGS is set. If PO_REQUIRE_TYPES or PO_STRICT_ARGS is set, then these variants are inaccessible; resolving to a variant with this flag set at parse time or run time causes an exception to be thrown. These variants are included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments.

CONST

Code with this flag is safe to be used when assigning a constant, because it has no side effects and normally does not throw an exception (at least in the context of assigning a constant).

DEPRECATED

Code with this flag is deprecated and will be removed in a future version of Qore; if a variant with this flag is resolved at parse time, a deprecated warning is raised (assuming this warning is enabled).
