|This interface defines the methods any general editor should be able
to implement. |
Having this interface enables complex components (the client of the
editor) such as
JTable to allow any generic editor to
edit values in a table cell, or tree cell, etc. Without this generic
JTable would have to know about specific editors,
etc. In addition, without this interface, clients of editors such as
JTable would not be able
to work with any editors developed in the future by the user
or a 3rd party ISV.
To use this interface, a developer creating a new editor can have the
new component implement the interface. Or the developer can
choose a wrapper based approach and provide a companion object which
CellEditor interface (See
JCellEditor for example). The wrapper approach
is particularly useful if the user want to use a 3rd party ISV
JTable, but the ISV didn't implement the
CellEditor interface. The user can simply create an object
that contains an instance of the 3rd party editor object and "translate"
CellEditor API into the 3rd party editor's API.
