public BasicValuedMapping resolveFunctionReturnType(Supplier<BasicValuedMapping> impliedTypeAccess, List<? extends SqlAstNode> arguments)

Implements org.hibernate.query.sqm.produce.function.FunctionReturnTypeResolver.resolveFunctionReturnType.

Doc from org.hibernate.query.sqm.produce.function.FunctionReturnTypeResolver.resolveFunctionReturnType.

Resolve the return type for a function given its context-implied type and the arguments to this call.

The context-implied type is the type implied by where the function occurs in the query. E.g., for an equality predicate (`something = some_function`) the implied type of the return from `some_function` would be defined by the type of `some_function`.

Returns:BasicValuedMapping

The resolved type.
