Package com.complexible.stardog.plan.filter.functions

Packaging containing the definition of a Function and all the built-in implementations for strings, dates, etc.

Primarily, the Function implementations correspond to some defined XPath function, which is usually noted in the documentation for the function itself. There are a few which are non-XPath functions which are specific to either the SPARQL specification or SWRL. See XPathFunctions for an incomplete list of which XPath functions are implemented in Stardog.

Functions available via FunctionRegistry can be used as custom SPARQL functions at query time. See Function for information on binding new implementations of Function at runtime.

Registration of the core Stardog Functions is performed by SPARQLFunctions
