Declaration
Remarks
Implement this interface in addition to the ICustomFunctionOperator interface to make your custom function available for end-users in Expression Editors. If you want to use your custom function in CriteriaOperator-based criteria on the server side (to query a database), implement the ICustomFunctionOperatorFormattable interface as well.
