 ReturnableType<T> impliedResultType,
 QueryEngine queryEngine)

Description copied from class: AbstractSqmFunctionDescriptor

Return an SQM node or subtree representing an invocation of this function with the given arguments. This method may be overridden in the case of function descriptors that wish to customize creation of the node.

Overrides:

generateSqmFunctionExpression in class CastStrEmulation

Parameters:

arguments - the arguments of the function invocation

impliedResultType - the function return type as inferred from its usage
