org.teiid.query.optimizer.capabilities.SourceCapabilities.supportsFunction()
This method can be used to check whether a particular function is supported by this connector. This method should only be used if the capability FUNCTION is true. @param functionName The function that may be supported (see MetaMatrix documentation for further definition of the functions and their parameters.) @return True if function is supported.

        Schema schema = function.getFunctionDescriptor().getMethod().getParent();
        if (schema == null) {
            // Find capabilities
            SourceCapabilities caps = getCapabilities(modelID, metadata, capFinder);


            if (!caps.supportsFunction(function.getFunctionDescriptor().getName().toLowerCase())) {
                return false;
            }
        } else if (!schema.getFullName().equalsIgnoreCase(metadata.getFullName(modelID))) {
          return false; //not the right schema
        }
