```
public static Value.Type[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (Value.Type c : Value.Type.values()) System.out.println(c);
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Value.Type valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    Parameters:
    name - the name of the enum constant to be returned.
    Returns:
    the enum constant with the specified name
    Throws:
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    java.lang.NullPointerException - if the argument is null
  - createDefault
```
public Value createDefault()
```
    Creates a default value.
    Returns:
    A new default value.
  - getDefaultValue
```
public Value getDefaultValue(boolean isNullAllowed)
```
    Gets a shared instance of a null or default Value of the specified type depending on the isNullAllowed flag.
    Parameters:
    isNullAllowed - Flag for null allowed.
    Returns:
    The default or null Value of the value type.
    Throws:
    java.lang.IllegalArgumentException - If type is not valid.
  - getSQLType
```
public int getSQLType()
```
    Gets the default SQL type for this Type.
    Returns:
    The SQL type, or Types.JAVA_OBJECT if no JDBC mapping is present.
  - canConvertTo
```
public boolean canConvertTo(Value.Type dest)
```
    Returns if this value can be converted to another value type. Data or precision loss is accepted in this conversion, e.g. losing the decimal part (conversion from Float to Integer) or the time part for (converting date-time to date). Note that String and KString are set to be convertable to all types, but they may fail often, e.g. String converted to Date fails due to wrong format.
    Parameters:
    dest - The destination type.
    Returns:
    true if it is possible to convert, but if the value conversion succeeds or fails depends on the value itself (e.g. convert Integer 256 to Byte will fail).
