build
Called during query plan construction immediately after the construction of the extension instance. Can throw ExprBuildException if something is wrong (like wrong number of arguments).- Parameters:
uri
- The function URIargs
- The parsed argumentscontext
- The build context.

build
Deprecated. -
exec
Test a list of values - argument will not be null but may have the wrong number of arguments. FunctionBase provides a more convenient way to implement a function. Can throw ExprEvalsException if something goes wrong.- Parameters:
binding
- The current solutionargs
- A list of unevaluated expressionsuri
- The name of thisenv
- The execution context- Returns:
- NodeValue - a value
-
