Constructor Detail

DiagnosticCache

public DiagnosticCache(org.eclipse.emf.common.notify.Notifier input)

Default constructor.

Parameters:

input - the input

Method Detail

isInitializing

protected final boolean isInitializing()

Queries whether the cache is in the process of initializing itself. This is useful to avoid doing redundant work, such as back-tracking up an EMF containment tree to update parents that have already been covered during the initialization.

Returns:

whether the cache is in the process of initializations

Since:

1.17

getDefaultValue

public org.eclipse.emf.common.util.Diagnostic getDefaultValue()

Description copied from class: AbstractCachedTree

Returns the default value for a cached node.
The root value will be initialized with this value, too

Specified by:

getDefaultValue in class AbstractCachedTree<org.eclipse.emf.common.util.Diagnostic>

Returns:

the default value for a cached tree node

createdCachedTreeNode

protected CachedTreeNode<org.eclipse.emf.common.util.Diagnostic> createdCachedTreeNode(org.eclipse.emf.common.util.Diagnostic value)

Description copied from class: AbstractCachedTree

Creates a cached tree node.

Specified by:

createdCachedTreeNode in class AbstractCachedTree<org.eclipse.emf.common.util.Diagnostic>

Parameters:

value - the value stored by the cached tree node

Returns:

the created node

updateParentNode

protected void updateParentNode(Object parent,
                                Object object,
                                org.eclipse.emf.common.util.Diagnostic value)

Description copied from class: AbstractCachedTree

Updates the passed parent nodes cached value.

Overrides:

updateParentNode in class AbstractCachedTree<org.eclipse.emf.common.util.Diagnostic>

Parameters:

parent - the parent object to be updated

object - the object for which the cached value should be changed.

value - the the cached value for the object

Since:

1.17

getObjects

public Set<Object> getObjects()

Returns:

the objects with cached values.

getOwnValue

public org.eclipse.emf.common.util.Diagnostic getOwnValue(Object o)

Parameters:

o - the object

Returns:

the objects diagnostic

dispose

public void dispose()

Disposes this cache.

reinit

public void reinit(org.eclipse.emf.common.notify.Notifier notifier)

Does a reinit of this cache if the given notifier is different than the current one.

Parameters:

notifier - the notifier

registerValidationListener

public void registerValidationListener(DiagnosticCache.ValidationListener listener)

Parameters:

listener - the DiagnosticCache.ValidationListener to register

deregisterValidationListener

public void deregisterValidationListener(DiagnosticCache.ValidationListener listener)

Parameters:

listener - the DiagnosticCache.ValidationListener to deregister

updateCache

protected void updateCache(org.eclipse.emf.ecore.EObject element,
                           DiagnosticCache cache)

UPdates the cache and notifies listeners that this was a potential structure change.

Parameters:

element - the changed element

cache - the cache

updateCacheWithoutRefresh

protected void updateCacheWithoutRefresh(org.eclipse.emf.ecore.EObject element,
                                         DiagnosticCache cache)

Updates the cache and notifes listeners that this change was not a structure change.

Parameters:
