findOldStyleEnumField

@Nullable
private static Field findOldStyleEnumField(@NotNull
                                                     Class<?> clazz,
                                                     String name)

Returns:

public static final field with this name.

getOldStyleEnumFieldValue

public static Object getOldStyleEnumFieldValue(Class<?> toWhat,
                                               String value)

Support for int/string enum pattern. That means classes declaring constants with public static final fields to mimic enums, e. g. Locale.

Returns:

ObjectUtils.NULL: no such public static final field.

callConstructor

@NotNull
public static Object callConstructor(@NotNull
                                              Class<?> toWhat,
                                              String value)

To retrieve instances of classes with a single string-argument constructor like BigDecimal.BigDecimal(String), BigInteger.BigInteger(String).

toEnum

@NotNull
public static Object toEnum(@NotNull
                                     Class<?> toWhat,
                                     String value)

toTimestamp

@NotNull
public static Object toTimestamp(String value)

toTime

@NotNull
public static Object toTime(String value)

toSqlDate

@NotNull
public static Object toSqlDate(String value)

toDate

public static Object toDate(String value)

newRuntimeException

@NotNull
private static RuntimeException newRuntimeException(String value,
                                                             Class<?> toWhat)
