public PersistentObject(java.lang.String id)

Method Detail

setRepository

public void setRepository(Repository r)

getRepository

public Repository getRepository()

getRepository

public static Repository getRepository(java.lang.String type)

getStatements

public java.util.Hashtable getStatements()
                                  throws ServerException

Throws:

ServerException

load

public void load()
          throws ServerException

Throws:

ServerException

delete

public void delete()
            throws ServerException

Throws:

ServerException

save

public void save()
          throws ServerException

Throws:

ServerException

insert

public void insert()
            throws ServerException

Throws:

ServerException

setPrimaryKey

protected void setPrimaryKey(java.lang.String[] key)
                      throws ServerException

Throws:

ServerException

getPrimaryKey

public java.lang.String[] getPrimaryKey()

getID

public java.lang.String getID()

Overrides:

getID in class ServerObject

list

public Bag list()
         throws ServerException

Returns a list of all objects in the database in sortfield order. Note that this is preparedSQL so runs (slightly) faster than the Filter method

Throws:

ServerException

filter

public java.util.Vector filter(java.lang.String filter)
                        throws ServerException

Returns a list of all objects in the database meeting the filter criteria. Filter is an SQL WHERE clause, without the WHERE. Note that this is preparedSQL so runs (slightly) faster than the Filter method

Throws:

ServerException

getPropertyNames

public java.util.Vector getPropertyNames()

Update

public ServerObj Update(ServerContext ctx)
                 throws ServerException

Throws:

ServerException

init

public void init(SQLRepository repository,
                 java.lang.String table,
                 java.lang.String type,
                 java.lang.String sortfield)
          throws ServerException

Throws:

ServerException

getFieldList

public java.util.Vector getFieldList()

Overrides:

getFieldList in class ServerObject

getIntegerProperty

public java.lang.Integer getIntegerProperty(java.lang.String fieldName)

Get an integer field property from this persistent object. Note that aggregated SQL fields from e.g. the COUNT function return java.lang.Long on Linux, but java.lang.Integer on Windows XP, so we'd better be prepared for all the different OS flavors. Also, MySQL 5.x always seems to return java.math.BigInteger for integer values in result sets, unlike MySQL 4.x.

Parameters:

fieldName - The name of the wanted field property

Returns:

The integer value of the field

getBooleanProperty

public java.lang.Boolean getBooleanProperty(java.lang.String fieldName)

Get a Boolean field property from this persistent object. Boolean types can also be represented as integer values in the underlying SQL database. If that is the case do a conversion into a Boolean value.

Parameters:

fieldName - The name of the wanted field property

Returns:

The Boolean value of the field

destroy

public void destroy()
