columnValue

public Object columnValue(ColumnName columnName)

Obtains the value of the storage field by the specified column name.

The default column mapping will be used. It is suitable for storages that store values "as-is" or that are willing to do the manual column value conversion.

In other cases consider implementing a custom ColumnMapping and using the columnValue overload for convenient column value conversion.

Return

the storage field value

Parameters

columnName

the column name

Throws

if there is no column with the specified name

public R columnValue<R>(ColumnName columnName, ColumnMapping<R> columnMapping)

Obtains the value of the storage field by the specified column name.

The specified column mapping will be used to do the column value conversion.
