Class SumReturnTypeResolver

java.lang.Object

org.hibernate.dialect.function.SumReturnTypeResolver

All Implemented Interfaces:

FunctionReturnTypeResolver

public class SumReturnTypeResolver
extends Object
implements FunctionReturnTypeResolver

Resolve according to JPA spec 4.8.5

SUM returns:

• Long when applied to state fields of integral types (other than BigInteger);
• Double when applied to state fields of floating point types;
• BigInteger when applied to state fields of type BigInteger;
• and BigDecimal when applied to state fields of type BigDecimal.

Description copied from interface: FunctionReturnTypeResolver

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`.

Specified by:

resolveFunctionReturnType in interface FunctionReturnTypeResolver

Returns:

The resolved type.
