StoreUtil

public StoreUtil()

Method Detail

dbFields

public static java.util.Vector dbFields(Persistent o)

Returns the fields of Object which have corresponding fields in the database.

Returns:

a vector containing the persistent fields of the class.

dbMultiValuedFields

public static java.util.Vector dbMultiValuedFields(Persistent o)

Returns the multivalued fields (Vectors and Hashtables) of Object which have corresponding fields in the database.

Returns:

a vector containing the persistent multivalued fields of the class.

cleanDbFieldV

public static void cleanDbFieldV()

dbAttrs

public static java.lang.String dbAttrs(Persistent o,
                                       java.lang.String prefix)

dbAttrsCount

public static int dbAttrsCount(Persistent o)

dbAttrs

public static java.lang.String dbAttrs(Persistent o)

hasClassAttribute

public static boolean hasClassAttribute(java.lang.Class c)

dbAttrPos

public static int dbAttrPos(Persistent o,
                            java.lang.String fieldname)

setValues

public static void setValues(Persistent o,
                             java.util.Map req)
                      throws ApplicationException

Throws:

ApplicationException

setValues

public static void setValues(Persistent o,
                             java.util.Map req,
                             java.util.Map fieldmodes)
                      throws ApplicationException

Throws:

ApplicationException

setFromDB

public static void setFromDB(Persistent o,
                             java.sql.ResultSet rs)
                      throws java.lang.Exception

Deprecated.

Set the members of the persistent object to the corresponding values of the current row of the result set. The object is added to the Thread-Cache. This method normally uses setFromRS. When the property database.setfromdb.compatibility is set in the configuration, setFromRSByName is used.

Parameters:

o - The persistent object

rs - the ResultSet

Throws:

java.lang.Exception

setFromDB

public static void setFromDB(Persistent o,
                             java.sql.ResultSet rs,
                             boolean addToCache)
                      throws java.lang.Exception

Deprecated.

Set the members of the persistent object to the corresponding values of the current row of the result set. This method nornmally uses setFromRS. When the property database.setfromdb.compatibility is set in the configuration, setFromRSByName is used.

Parameters:

o - The persistent object

rs - the ResultSet

addToCache - if true, the object is added to the Thread-Cache.

Throws:

java.lang.Exception

setFromRSByName

public static void setFromRSByName(Persistent o,

                            throws java.lang.Exception

Set the members of the persistent object to the corresponding values of the current row of the result set. The object is added to the Thread-Cache. The method uses a conventional metadata based approach to determine the position and data types of the fields of the ResultSet and is somewhat slower than setFromRS.

Parameters:

o - The persistent object

rs - the ResultSet

Throws:

java.lang.Exception

                            throws java.lang.Exception

Set the members of the persistent object to the corresponding values of the current row of the result set. The method uses a conventional metadata based approach to determine the position and data types of the fields of the ResultSet and is somewhat slower than setFromRS.

Parameters:

o - The persistent object

rs - the ResultSet

addToCache - if true, the object is added to the Thread-Cache.

Throws:

java.lang.Exception

setFromRS

Set the members of the persistent object to the corresponding values of the current row of the result set. The object is added to the Thread-Cache. The method uses a fast approach to determine the position and data types of the fields of the ResultSet.

Parameters:

o - The persistent object

rs - the ResultSet

Throws:

java.lang.Exception
