Interface ExtendedType

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

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.
 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.
 

Method Detail

getClassName

String getClassName()
Returns a full name of Java class that this ExtendedType supports.


validateProperty

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.

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.

Since:
1.1

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 ocurred, 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.
