Method Details

connect
Deprecated.Description copied from interface:IDocumentProviderConnects the given element to this document provider. This tells the provider that caller of this method is interested to work with the document provided for the given domain model element. By counting the invocations of this method anddisconnect(Object)this provider can assume to know the correct number of clients working with the document provided for that domain model element.The given element must not be
null.- Specified by:
connectin interfaceIDocumentProvider- Parameters:
element- the element- Throws:
CoreException- if the textual representation or the annotation model of the element could not be created
-
disconnect
Deprecated.Description copied from interface:IDocumentProviderDisconnects the given element from this document provider. This tells the provider that the caller of this method is no longer interested in working with the document provided for the given domain model element. By counting the invocations ofconnect(Object)and of this method this provider can assume to know the correct number of clients working with the document provided for that domain model element.The given element must not be

element- the element, ornull- Returns:
- the annotation model, or
nullif none
-
aboutToChange
Deprecated.Description copied from interface:IDocumentProviderInforms this document provider about upcoming changes of the given element. The changes might cause change notifications specific for the type of the given element. If this provider manages a document for the given element, the document provider must not change the document because of the notifications received afteraboutToChangehas been and beforechangedis called. In this case, it is assumed that the document is already up to date, e.g., a save operation is a typical case.The concrete nature of the change notification depends on the concrete type of the given element. If the element is, e.g., an
IResourcethe notification is a resource delta.- Specified by:
aboutToChangein interfaceIDocumentProvider- Parameters:
element- the element, ornull
-
changed
Deprecated.Description copied from interface:IDocumentProviderInforms this document provider that the given element has been changed. All notifications have been sent out. If this provider manages a document for the given element, the document provider must from now on change the document on the receipt of change notifications. The concrete nature of the change notification depends on the concrete type of the given element. If the element is, e.g., anIResourcethe notification is a resource delta.- Specified by:
changedin interfaceIDocumentProvider- Parameters:
element- the element, ornull
-
addElementStateListener
Deprecated.Description copied from interface:IDocumentProviderAdds the given element state listener to this document provider. Has no effect if an identical listener is already registered.- Specified by:
addElementStateListenerin interfaceIDocumentProvider- Parameters:
listener- the listener
-
removeElementStateListener
Deprecated.Description copied from interface:IDocumentProviderRemoves the given element state listener from this document provider. Has no effect if an identical listener is not registered.- Specified by:
removeElementStateListenerin interfaceIDocumentProvider- Parameters:
listener- the listener
-
isReadOnly
Deprecated.Description copied from interface:IDocumentProviderExtensionReturns whether the document provider thinks that the given element is read-only. If this method returnstrue,saveDocumentcould fail. This method does not say anything about the document constructed from the given element. If the given element is not connected to this document provider, the return value is undefined. Document providers are allowed to use a cache to answer this question, i.e. there can be a difference between the "real" state of the element and the return value.- Specified by:
isReadOnlyin interfaceIDocumentProviderExtension- Parameters:
element- the element- Returns:
trueif the given element is read-only,falseotherwise
-
isModifiable
Deprecated.Description copied from interface:IDocumentProviderExtensionReturns whether the document provider thinks that the given element can persistently be modified. This is orthogonal toisReadOnlyas read-only elements may be modifiable and writable elements may not be modifiable. If the given element is not connected to this document provider, the result is undefined. Document providers are allowed to use a cache to answer this question, i.e. there can be a difference between the "real" state of the element and the return value.- Specified by:
isModifiablein interfaceIDocumentProviderExtension- Parameters:
element- the element- Returns:
trueif the given element is modifiable,falseotherwise
-
validateState
Deprecated.Description copied from interface:IDocumentProviderExtensionValidates the state of the given element. This method may change the "real" state of the element. If using, it also updates the internal caches, so that this method may also change the results returned byisReadOnlyandisModifiable. If the given element is not connected to this document provider, the effect is undefined.- Specified by:
validateStatein interfaceIDocumentProviderExtension- Parameters:
element- the elementcomputationContext- the context in which the computation is performed, e.g., a SWT shell- Throws:
CoreException- if validating fails
-
isStateValidated
Deprecated.Description copied from interface:IDocumentProviderExtensionReturns whether the state of the given element has been validated.- Specified by:
isStateValidatedin interfaceIDocumentProviderExtension- Parameters:
element- the element- Returns:
trueif the state has been validated
-
updateStateCache
Deprecated.Description copied from interface:IDocumentProviderExtensionUpdates the state cache for the given element. This method may change the result returned byisReadOnlyandisModifiable. If the given element is not connected to this document provider, the effect is undefined.- Specified by:
updateStateCachein interfaceIDocumentProviderExtension- Parameters:
element- the element- Throws:
CoreException- if validating fails
-
setCanSaveDocument
Deprecated.Description copied from interface:IDocumentProviderExtensionMarks the document managed for the given element as savable. I.e.canBeSaved(element)will returntrueafterwards.- Specified by:
