Constructor Detail

FloatRDBMSMapping

protected FloatRDBMSMapping(StoreManager storeMgr,
                            JavaTypeMapping mapping)

Parameters:

storeMgr - Store Manager

mapping - THe java type mapping

FloatRDBMSMapping

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

Constructor.

Parameters:

mapping - The java type mapping

storeMgr - Store Manager

field - Field to be 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

Overrides:

getTypeInfo in class DoubleRDBMSMapping

Returns:

The TypeInfo

getFloat

public float getFloat(java.lang.Object rs,
                      int param)

Description copied from interface: DatastoreMapping

Obtains a value from resultSet at position specified by exprIndex.

Specified by:

getFloat in interface DatastoreMapping

Overrides:

getFloat in class DoubleRDBMSMapping

Parameters:

rs - an object returned from the datastore with values

param - the position of the value in the result

Returns:

the value

setFloat

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

Description copied from interface: DatastoreMapping

Sets a value into preparedStatement at position specified by paramIndex.

Specified by:

setFloat in interface DatastoreMapping

Overrides:

setFloat in class DoubleRDBMSMapping

Parameters:

ps - a datastore object that executes statements in the database

param - the position of the value in the statement

value - the value

setObject

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

Description copied from interface: DatastoreMapping

Sets a value into preparedStatement at position specified by paramIndex.

Specified by:

setObject in interface DatastoreMapping

Overrides:

setObject in class DoubleRDBMSMapping

Parameters:

ps - a datastore object that executes statements in the database

param - the position of the value in the statement

value - the value

getObject

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

Description copied from interface: DatastoreMapping

Obtains a value from resultSet at position specified by exprIndex.

Specified by:

getObject in interface DatastoreMapping

Overrides:

getObject in class DoubleRDBMSMapping

Parameters:

rs - an object returned from the datastore with values

param - the position of the value in the result

Returns:

the value
