## org.apache.cayenne.access.types
Class EnumType<T extends Enum<T>>

    java.lang.Object
      org.apache.cayenne.access.types.EnumType<T>

All Implemented Interfaces:
  ExtendedType

    public class EnumType<T extends Enum<T>>

extends Object
implements ExtendedType

An ExtendedType that handles an enum class. If Enum is mapped to a character column, its name is used as persistent value; if it is mapped to a numeric column, its ordinal (i.e. a position in enum class) is used.

Requires Java 1.5 or newer

Since:
  1.2

Field Summary
`protected Class<T>` | `enumClass`
`protected Object[]` | `values`

Constructor Summary
`EnumType(Class<T> enumClass)`

Method Summary
`String` | `getClassName()` Returns a full name of Java class that this ExtendedType supports.
`Object` | `materializeObject(CallableStatement rs, int index, int type)` Reads an object from a stored procedure OUT parameter, converting it to class returned by 'getClassName' method.
`Object` | `materializeObject(ResultSet rs, int index, int type)` Reads an object from JDBC ResultSet column, converting it to class returned by 'getClassName' method.
`void` | `setJdbcObject(PreparedStatement statement, Object value, int pos, int type, int precision)` Initializes a single parameter of a PreparedStatement with object value.
`boolean` | `validateProperty(Object source, String property, Object value, DbAttribute dbAttribute, ValidationResult validationResult)` Deprecated. since 3.0 as validation should not be done at the DataNode level.

                                    ValidationResult validationResult)

  Deprecated. since 3.0 as validation should not be done at the DataNode level.

  Description copied from interface: `ExtendedType`
  Performs validation of an object property. Property is considered valid if this it satisfies the database constraints known to this ExtendedType. In case of validation failure, failures are appended to the ValidationResult object and `false` is returned.
