IStateValidationSupport (Eclipse Platform API Specification)

```
public interface IStateValidationSupport
```
Implementers of IFileBuffer may also implement IStateValidationSupport in order to allow a IFileBufferManager to batch the stages of state validation when calling IFileBufferManager.validateState(IFileBuffer[], org.eclipse.core.runtime.IProgressMonitor, Object).

Since:

3.1

Modifier and Type	Method	Description
`void`	`validationStateAboutToBeChanged()`	Tells this buffer that the validation state is about to be changed.

`void`	`validationStateChangeFailed()`	Tells this buffer that a initiated state validation failed.

- Method Detail
  - validationStateAboutToBeChanged
```
void validationStateAboutToBeChanged()
```
    Tells this buffer that the validation state is about to be changed. File buffer listeners will receive a IFileBufferListener.stateChanging(IFileBuffer) notification in response.
  - validationStateChanged
```
void validationStateChanged(boolean validationState,
                            IStatus status)
```
    Tells this buffer that the validation state has been changed to the given value. After that call, IFileBuffer.isStateValidated() will return the given value. Also IFileBuffer.getStatus() will returns the provided status. File buffer listeners will receive a IFileBufferListener.stateValidationChanged(IFileBuffer, boolean) notification.
    
    Parameters:
    
    validationState - true if validated, false otherwise
    
    status - the status of the executed validate state operation
  - validationStateChangeFailed
```
void validationStateChangeFailed()
```
    Tells this buffer that a initiated state validation failed. File buffer listeners will receive a IFileBufferListener.stateChangeFailed(IFileBuffer) notification in response.
