Constructor Detail

ChangeableDataRow

protected ChangeableDataRow()

Internal default constructor for the MemDataBook.

ChangeableDataRow

public ChangeableDataRow(IRowDefinition pRowDefinition)
                  throws ModelException

Constructs a DataRow with a given IRowDefinition.

Parameters:

pRowDefinition - the IRowDefinition

Throws:

ModelException - if the IRowDefintion is null or empty

ChangeableDataRow

protected ChangeableDataRow(IRowDefinition pRowDefinition,
                            Object[] pData,
                            IDataPage pDataPage,
