Method Detail

canonicalToDisplayValue

public Object canonicalToDisplayValue(ILayerCell cell,
                                      IConfigRegistry configRegistry,
                                      Object canonicalValue)

Description copied from interface: IDisplayConverter

Convert backing data value to value to be displayed. Typically converts to a String for display. Use this method for contextual conversion.

Note that on returning a different type than String, toString() will be called on the returned object to render the value for displaying.

Specified by:

canonicalToDisplayValue in interface IDisplayConverter

Specified by:

canonicalToDisplayValue in class ContextualDisplayConverter

Parameters:

cell - The ILayerCell whose canonical value should be converted.

configRegistry - The IConfigRegistry of the NatTable to which the ILayerCell belongs.

canonicalValue - The data value from the backing data.

Returns:

The converted value to display.

displayToCanonicalValue

public Object displayToCanonicalValue(ILayerCell cell,
                                      IConfigRegistry configRegistry,
                                      Object displayValue)

Description copied from interface: IDisplayConverter

Convert from display value to value in the backing data structure.

NOTE:
The type the display value is converted to must match the type in the setter of the backing bean/row object Use this method for contextual conversion.

Specified by:

displayToCanonicalValue in interface IDisplayConverter

Specified by:

displayToCanonicalValue in class ContextualDisplayConverter

Parameters:

cell - The ILayerCell whose canonical value should be converted.

configRegistry - The IConfigRegistry of the NatTable to which the ILayerCell belongs.

displayValue - The display value that should be converted to the data value that matches the backing data.

Returns:

The converted value to put to the backing data.

registerMarkup

public void registerMarkup(String value,
                           String markupPrefix,
                           String markupSuffix)

Registers a value and the markup that should be placed around the value while rendering.

Parameters:

value - The value that should be replacement with the markup for rendering.

markupPrefix - The String that will be added as prefix to the value.

markupSuffix - The String that will be added as suffix to the value.

registerRegexMarkup

public void registerRegexMarkup(String value,
                                String markupPrefix,
                                String markupSuffix)
