org.eclipse.rse.subsystems.files.core.util
Class ValidatorFileUniqueName

java.lang.Object
  extended by 

org.eclipse.rse.ui.validators.ValidatorUniqueString
      extended by 
org.eclipse.rse.subsystems.files.core.util.ValidatorFileUniqueName
All Implemented Interfaces:
IInputValidator, ICellEditorValidator, ISystemValidator, ISystemValidatorUniqueString

public class ValidatorFileUniqueName
extends ValidatorUniqueString

This class is used in dialogs that prompt for file or folder names, and those names need to be unique within a given folder. To make sure error checking while typing is fast, we go get the list of names of the files and folders in the constructor and re-use it from then on.

The IInputValidator interface is implemented by our parent and it is used by jface's InputDialog class and property sheet window.

If you subclass this, consider overriding the getFileNameValidator and getFolderNameValidator methods.
