Interface ExtendedType

All Known Implementing Classes:
  BigDecimalType, BigIntegerType, BooleanType, ByteArrayType, ByteType, CalendarType, CharType, DateType, DoubleType, EnumType, ExtendedEnumType, FloatType, IngresBooleanType, IntegerType, LongType, ObjectType, OracleByteArrayType, OracleCharType, OracleUtilDateType, ShortType, TimestampType, TimeType, UtilDateType, UUIDType, VoidType

    public interface ExtendedType

Defines methods to read Java objects from JDBC ResultSets and write as parameters of PreparedStatements.

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 scale)` Initializes a single parameter of a PreparedStatement with object value.

Method Detail

### getClassName

    String getClassName()

  Returns a full name of Java class that this ExtendedType supports.

### setJdbcObject

    void setJdbcObject(PreparedStatement statement,
                       Object value,
                       int pos,
                       int type,
                       int scale)
                       throws Exception

  Initializes a single parameter of a PreparedStatement with object value.

  Throws:
    `Exception`

### materializeObject

    Object materializeObject(ResultSet rs,
                             int index,
                             int type)
                             throws Exception

  Reads an object from JDBC ResultSet column, converting it to class returned by 'getClassName' method.

  Throws:
    `Exception` - if read error occurred, or an object can't be converted to a target Java class.

### materializeObject

    Object materializeObject(CallableStatement rs,
                             int index,
                             int type)
                             throws Exception

  Reads an object from a stored procedure OUT parameter, converting it to class returned by 'getClassName' method.

  Throws:
    `Exception` - if read error ocurred, or an object can't be converted to a target Java class.
