Interface CellDataResolver

All Known Implementing Classes:

DefaultDataResolver

public interface CellDataResolver

A CellDataResolver delivers a cell value that depends on two input parameters. The two input parameters consist of a certain row object and a certain column object and the CellDataResolver processes them to compute the resulting cell value from these two parameters.

Method Summary

Modifier and Type	Method and Description
boolean	applicableFor(Class data1, Class data2) Specifies the types/classes, this CellDataResolver could process.
String	getDisplayName() Returns the String that is displayed as name for this CellDataResolver (could be a localized name depending on the session language)
List<ParameterDescriptor>	getParameters() Returns a list of parameters that are expected/required by this CellDataResolver
void	init(TableBlock table, CellEntry entry, Map<String,Object> params) Initializes this CellDataResolver
Object	resolve(Object rowData, Object columnData) Processes the given row and column objects and returns the resulting cell value.

Method Detail

getDisplayName

String getDisplayName()

Returns the String that is displayed as name for this CellDataResolver (could be a localized name depending on the session language)

Returns:

The String that is displayed as name for this CellDataResolver (could be a localized name depending on the session language)

applicableFor

boolean applicableFor(Class data1,
                      Class data2)

Specifies the types/classes, this CellDataResolver could process.

Parameters:

data1 - The row entry's type/class

data2 - The column entry's type/class

Returns:

True, if this CellDataResolver is able to handle the given combindation of row and column entry type

resolve

Object resolve(Object rowData,
               Object columnData)
        throws DataResolverException

Processes the given row and column objects and returns the resulting cell value.

Parameters:

rowData - A concrete row data object

columnData - A concrete column data Object

Returns:

A cell value object (e.g. a String)

Throws:

DataResolverException - If an error occurs while computing the resulting cell value

getParameters

List<ParameterDescriptor> getParameters()

Returns a list of parameters that are expected/required by this CellDataResolver

Returns:

A list of parameters that are expected/required by this CellDataResolver

init

void init(TableBlock table,
          CellEntry entry,
          Map<String,Object> params)

Initializes this CellDataResolver

Parameters:

table - The table this CellDataResolver is used within

entry - The CellEntry this CellDataResolver is related to

params - The parameters this CellDataResolver expects (see also: CellDataResolver.getParameters())
