Interface IFileModificationValidator
-
All Known Implementing Classes:
-
FileModificationValidator
Deprecated. clients should subclass
FileModificationValidator instead
of implementing this interface
-
public interface IFileModificationValidator
The file modification validator is a Team-related hook for pre-checking operations
that modify the contents of files.
This interface is used only in conjunction with the
"org.eclipse.core.resources.fileModificationValidator"
extension point. It is intended to be implemented only
by the Eclipse Platform Team plug-in.

Since:
- 2.0
validateEdit
IStatus validateEdit(
IFile[] files,
Object context)
-
Deprecated.
- Validates that the given files can be modified. The files must all exist
in the workspace. The optional context object may be supplied if
UI-based validation is required. If the context is
null, the
validator must attempt to perform the validation in a headless manner.
The returned status is IStatus.OK if this validator
believes the given file can be modified. Other return statuses indicate
the reason why the individual files cannot be modified.
-
-
Parameters:
-
files - the files that are to be modified; these files must all exist in the workspace -
context - the org.eclipse.swt.widgets.Shell that is to be used to
parent any dialogs with the user, or null if there is no UI context (declared
as an Object to avoid any direct references on the SWT component)
-
Returns:
- a status object that is OK if things are fine, otherwise a status describing
reasons why modifying the given files is not reasonable
-
See Also:
-
IWorkspace.validateEdit(IFile[], Object)
validateSave
IStatus validateSave(
IFile file)
-
Deprecated.
- Validates that the given file can be saved. This method is called from
IFile#setContents and IFile#appendContents
before any attempt to write data to disk. The returned status is
IStatus.OK if this validator believes the given file can be
successfully saved. In all other cases the return value is a non-OK status.
Note that a return value of IStatus.OK does not guarantee
that the save will succeed.

-
Parameters:
-
file - the file that is to be modified; this file must exist in the workspace
-
Returns:
- a status indicating whether or not it is reasonable to try writing to the given file;
IStatus.OK indicates a save should be attempted. -
