Method Detail

invariant

public static FunctionReturnTypeResolver invariant(BasicType<?> invariantType)

A resolver that defines an invariant result type. E.g. `substring` always returns a String. Note however that to account for attribute converters and such, this resolver allows the context-implied expression type to be the return type so long as the Java types are compatible.

useArgType

public static FunctionReturnTypeResolver useArgType(int argPosition)

useFirstNonNull

public static FunctionReturnTypeResolver useFirstNonNull()

isAssignableTo

@Internal
public static boolean isAssignableTo(ReturnableType<?> defined,
                                     ReturnableType<?> implied)

useImpliedTypeIfPossible

@Internal
public static BasicValuedMapping useImpliedTypeIfPossible(BasicValuedMapping defined,
                                                          BasicValuedMapping implied)

extractArgumentType

public static ReturnableType<?> extractArgumentType(List<? extends SqmTypedNode<?>> arguments,
                                                    int position)

extractArgumentJdbcMapping

public static JdbcMapping extractArgumentJdbcMapping(TypeConfiguration typeConfiguration,
                                                     List<? extends SqmTypedNode<?>> arguments,
                                                     int position)

extractArgumentValuedMapping

public static BasicValuedMapping extractArgumentValuedMapping(List<? extends SqlAstNode> arguments,
                                                              int position)
