Interface VFXMappingTableCell<T,E>

Type Parameters:

T - the data type in the table

E - the data type the cell is going to use from items of type VFXMappingTableCell

All Superinterfaces:

VFXCell<T>, VFXTableCell<T>

All Known Implementing Classes:

VFXObservingTableCell, VFXSimpleTableCell

public interface VFXMappingTableCell<T,E>
extends VFXTableCell<T>

Extension of VFXTableCell to propose users a specific way of using VFXTable. I structured this virtualized container with this API in mind. Each VFXTableColumn should produce cells that display from an object VFXMappingTableCell that comes from the model, a piece of data VFXMappingTableCell which is part of VFXMappingTableCell. Consider this example:

 
 // My model class...
 record User(int id, String name) {}
 // My columns (assuming UserCell is a custom cell)
 VFXTableColumn<User, UserCell> idColumn = new VFXDefaultTableColumn<>("ID");
 VFXTableColumn<User, UserCell> nameColumn = new VFXDefaultTableColumn<>("Name");
 // Let's set their cell factories
 idColumn.setCellFactory(user -> new UserCell(user, User::id));
 nameColumn.setCellFactory(user -> new UserCell(user, User::name));
 // See the second parameter in the constructors? I call that function the 'extractor' which basically tells the cell
 // which piece of data it should display from the a User object
 
 

For this API to work, we need two additional requirements:

1) Cells need to have an 'extractor' function

2) Cells may want to also have a 'converter' function. This is going to be used to convert extracted data of type VFXMappingTableCell to string to be used, for example, in a label. Of course, this is optional if the data is not going to be displayed as a string

Method Summary

Modifier and Type	Method	Description
StringConverter<E>	getConverter()
Function<T,E>	getExtractor()
default VFXMappingTableCell<T,E>	setConverter(Function<E,String> fn)	Allows easily setting a StringConverter for the cell by just giving a Function as parameter, makes use of FunctionalStringConverter.to(Function).
VFXMappingTableCell<T,E>	setConverter(StringConverter<E> converter)	Sets the StringConverter used to convert an extracted value VFXMappingTableCell to a String
VFXMappingTableCell<T,E>	setExtractor(Function<T,E> extractor)	Sets the function used to extract a value VFXMappingTableCell from an item VFXMappingTableCell
