Constructor Detail

DoubleRDBMSMapping

protected DoubleRDBMSMapping(StoreManager storeMgr,
                             JavaTypeMapping mapping)

Parameters:

storeMgr - Store Manager

mapping - The java type mapping

DoubleRDBMSMapping

public DoubleRDBMSMapping(JavaTypeMapping mapping,
                          StoreManager storeMgr,
                          DatastoreField field)

Constructor.

Parameters:

mapping - The java type mapping

storeMgr - Store Manager

field - Field being mapped

Method Detail

getTypeInfo

public TypeInfo getTypeInfo()

Description copied from class: ColumnMapping

Returns the TypeInfo (JDBC SQL type) for columns. This method is capable of returning only one TypeInfo (SQL Type). In that way, it seems adequate for using in 1 column Mapping or many columns that share the same TypeInfo. However adequate in most of uses, Mappings using two or more columns should overwrite the initTypeInfo method to appropriate set differents TypeInfo (SQL type) for all the columns

Specified by:

getTypeInfo in class ColumnMapping

Returns:

The TypeInfo

getDatastoreField

public DatastoreField getDatastoreField()

Description copied from interface: DatastoreMapping

The datastore field mapped

Specified by:

getDatastoreField in interface DatastoreMapping

Overrides:

getDatastoreField in class ColumnMapping

Returns:

the DatastoreField

setInt

public void setInt(java.lang.Object ps,
                   int param,
                   int value)

Description copied from interface: DatastoreMapping

Sets a value into preparedStatement at position specified by paramIndex.

Specified by:

setInt in interface DatastoreMapping

Overrides:

setInt in class RDBMSMapping

Parameters:

ps - a datastore object that executes statements in the database

param - the position of the value in the statement

getInt

public int getInt(java.lang.Object rs,
                  int param)

Description copied from interface: DatastoreMapping

Obtains a value from resultSet at position specified by exprIndex.

Specified by:

getInt in interface DatastoreMapping

Overrides:

getInt in class RDBMSMapping

Parameters:

rs - an object returned from the datastore with values

setLong

public void setLong(java.lang.Object ps,
                    int param,
