Value class constructor with a default converter. This implementation uses a DefaultStringLiteralConverter.

Parameters:

valueClass - The class indicating the type of value to convert.

componentClass - The class of component to create.

Throws:

java.lang.NullPointerException - if the given value class and/or component class is null.

java.lang.IllegalArgumentException - if the given component class does not have a constructor with a single InfoModel constructor.

Method Detail

getConverter

public Converter<VV,java.lang.String> getConverter()

Returns:

The converter to use for displaying the value as a string.

createComponent

public Component createComponent(ListSelectModel<VV> model,
                                 VV value,
                                 int index,
                                 boolean selected,
                                 boolean focused)

Creates a component for the given list value. This implementation constructs a component from a info model that converts the value using the saved converter.

Specified by:

createComponent in interface ListSelectControl.ValueRepresentationStrategy<VV>

Parameters:

model - The model containing the value.

value - The value for which a component should be created.

index - The index of the value within the list, or -1 if the value is not in the list (e.g. for representing no selection).

selected - true if the value is selected.

focused - true if the value has the focus.

Returns:

A new component to represent the given value.
