Methods
 NameDescription
Protected methodAccumulateChangeData
(Inherited from SuspendableDocumentNodeWithSetOfEventArgs)
Protected methodAccumulatedChangeData_SetBackAfterResumeAndSuspend
(Inherited from SuspendableDocumentNodeWithSetOfEventArgs)
Protected methodAccumulatedEventData_Clear Clears the accumulated event data.
(Inherited from SuspendableDocumentNodeWithSetOfEventArgs)
Protected methodAccumulatedEventData_HasZeroOrOneEventArg Determines whether there is no or only one single event arg accumulated. If this is the case, the return value is true. If there is one event arg accumulated, it is returned in the argument singleEventArg. The return value is false if there is more than one event arg accumulated. In this case the singleEventArg is null on return, and the calling function should use AccumulatedEventData to enumerate all accumulated event args.
(Inherited from SuspendableDocumentNodeWithSetOfEventArgs)
Public methodAdd 
Protected methodChildCloneFromT Clones a node that is intended to use as child node of this instance (e.g. in collections). Consider using ChildCloneToMemberT(T, T) instead if the child node is stored in a member of this instance.
(Inherited from SuspendableDocumentNode)
Protected methodChildCloneToMemberT Sets a member variable that holds a child with a cloned instance of another variable. If an old instance member (provided in myChild exists and can not be used, it is disposed first. The node is then cloned using System.ICloneable. The resulting node's ParentObject is then set to this instance in order to maintain the parent-child relationship.
(Inherited from SuspendableDocumentNode)
Protected methodChildCloneToMemberAltT Set a member variable that holds a child node of this instance. The child node may or may not implement IDocumentLeafNode. The value to set may or may not implement ICloneable. If it implements ICloneable, then the member variable is set to a clone of the value. Otherwise, the member variable is set directly with the value. It helps to ensure the correct order: first, the child node is set to the new instance and then the old child node is disposed.
(Inherited from SuspendableDocumentNode)
Protected methodChildCopyToMemberT Copies a document node from another source into a member of this instance. If an old instance member (provided in myChild exists and can not be used, it is disposed first. The node is then copied using either Main.ICopyFrom or System.ICloneable. The resulting node's ParentObject is then set to this instance in order to maintain the parent-child relationship.
(Inherited from SuspendableDocumentNode)
Protected methodChildCopyToMemberOrCreateNewT Copies a document node from another source into a member of this instance. If an old instance member (provided in myChild exists and can not be used, it is disposed first. If the node is not null, the node is then copied using either Main.ICopyFrom or System.ICloneable. If the node is null, a new node is created using the provided generation function. The resulting node's ParentObject is then set to this instance in order to maintain the parent-child relationship.
(Inherited from SuspendableDocumentNode)
Protected methodChildDisposeMemberT Helper function to dispose a child node of this instance. It helps to ensure the correct order: first, the child node is set to null and only then the child node is disposed.
(Inherited from SuspendableDocumentNodeBase)
Protected methodChildSetMemberT Set a member variable that holds a child node of this instance. It helps to ensure the correct order: first, the child node is set to the new instance and then the old child node is disposed.
(Inherited from SuspendableDocumentNode)
Protected methodChildSetMemberAltT Set a member variable that holds a child node of this instance. The child node may or may not implement IDocumentLeafNode. It helps to ensure the correct order: first, the child node is set to the new instance and then the old child node is disposed.
(Inherited from SuspendableDocumentNode)
Public methodClear 
Public methodContains(TItem) 
Public methodContains(String) Determines whether the collection contains a project item with the specified name and with the type that this collection stores.
Public methodContainsAnyName Determines whether the collection contains any project item with the specified name. This must not neccessarily a item of the type that this collection stores (some collections can have a shared name dictionary). In constrast, use Contains(String) to determine if the collection contains an item with the specified name and the native type that the collection stores.
Public methodCopyTo 
Public methodCountEvent Counts the number of events during the suspend state. Every call to this function will increment the event counter by 1 (but only in the suspended state). The event counter will be reset to zero when the object is resumed.
(Inherited from SuspendableDocumentNode)
Public methodDispose Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
(Inherited from SuspendableDocumentNodeBase)
Protected methodDispose(Boolean)Releases the unmanaged resources used by the ProjectItemCollectionBaseTItem and optionally releases the managed resources
(Overrides SuspendableDocumentNodeDispose(Boolean))
Public methodEhChildChanged Used by childs of this object to inform us about a change in their state.
(Inherited from SuspendableDocumentNode)
Public methodEhParentTunnelingEventHappened Is called by the parent when a tunneling event happened in the parent.
(Inherited from SuspendableDocumentNode)
Protected methodEhSelfChanged Called if some (simple) member or property of this instance itself has changed.
(Inherited from SuspendableDocumentNode)
Public methodEhSelfTunnelingEventHappened(TunnelingEventArgs) Is called by this instance if a tunneling event happened into this instance. The tunneling event triggers the TunneledEvent and is additionally distributed to all childs of this instance.
(Inherited from SuspendableDocumentNodeBase)
Public methodEhSelfTunnelingEventHappened(TunnelingEventArgs, Boolean) Is called by this instance if a tunneling event happened into this instance. The tunneling event triggers the TunneledEvent and is - depending on the provided parameter - also distributed to all childs of this instance.

(Overrides SuspendableDocumentNodeGetNameOfChildObject(IDocumentLeafNode))
Public methodGetSortedItemNames 
Public methodGetTypeGets the Type of the current instance.
(Inherited from Object)
Protected methodHandleHighPriorityChildChangeCases Handles the case when a child changes, and a reaction is neccessary independently on the suspend state of the table.
(Inherited from SuspendableDocumentNode)
Protected methodHandleLowPriorityChildChangeCases Processes the event args e when this object is not suspended. This function serves two purposes: i) updating some cached data of this object by processing the event args of the child, and ii) optional transforming the event args, for instance to a new type, which afterwards is send to the parent and is used as event args in the [E:Changed] event of this object. The transformed event args is not used if this object is suspended (in this case the original event args is used).
(Inherited from SuspendableDocumentNode)
Protected methodInternalAdd 
Protected methodInternalClear 
Protected methodInternalExchange 
Protected methodInternalRemove Removes the item from the collection. This function should only work on the internal structures, but do nothing else.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
Protected methodNotifyChildrenTunnelingEventHappened Notifies the child nodes of this instance that a tunneling event has happened.
(Inherited from SuspendableDocumentNode)
Protected methodOnAboutToBeResumed Is called when the suspend level is still 1 (one), but is about to fall to zero, i.e. shortly before the call to OnResume(Int32). This function is not called before OnResumeSilently(Int32)!
(Inherited from SuspendableDocumentNode)
Protected methodOnChanged
(Overrides SuspendableDocumentNodeBaseOnChanged(EventArgs))
Protected methodOnResume Is called when the object is resumed, i.e. change notifications are allowed again. During the execution of this function, the [P:IsResumeInProgress] property will return true to indicate that the resume is currently in progress.
(Inherited from SuspendableDocumentNode)
Protected methodOnResumeSilently Is called when the suspend level falls down from 1 to zero by a call to ResumeSilently. This implementation disarma the suspendTokens of the childs of this object, deletes any accumulated events, and does not send any change event to the parent or the listeners of the Change event.
(Inherited from SuspendableDocumentNode)
Protected methodOnSuspended Called when the suspend level has just gone from 0 to 1, i.e. the object was suspended.
(Inherited from SuspendableDocumentNode)
Protected methodOnTunnelingEvent Fires the TunneledEvent event.
(Inherited from SuspendableDocumentNodeBase)
Public methodRemove(TItem) Removes the item from the collection and disposes it. Only items that belong to this collection will be removed and disposed.
Public methodRemove(String) Removes the item, referenced by its name, from the collection and disposes it. Only items that belong to this collection will be removed and disposed.
Public methodRenameChild Helper function called by a child of this collection to handle renaming of this child.
Public methodResume(ISuspendToken) Resumes changed events by calling Resume for the provided suspend token, and setting the reference to the suspend token to null. If Event data were accumulated during the suspended state, a changed event is triggered for each event data.
(Inherited from SuspendableDocumentNodeBase)
Public methodResume(ISuspendToken, EventFiring) Resumes changed events, either with taking the accumulated event data into account (see Resume(ISuspendToken)) or discarding the accumulated event data (see ResumeSilently(ISuspendToken), depending on the provided argument eventFiring.
(Inherited from SuspendableDocumentNodeBase)
Public methodResumeCompleteTemporarily Resumes the object completely for only a short time. Thus, if object was suspended before, it will be suspended again when the function returns.
(Inherited from SuspendableDocumentNode)
Public methodResumeCompleteTemporarilyGetToken Resumes the object completely for the time the returned token is referenced and not disposed. The return value is a token that had 'absorbed' the suspend count of the object, resulting in the suspend count of the object dropped to 0 (zero). When the returned token is finally disposed, the suspend count of the object is increased again by the 'absorbed' suspend count.
(Inherited from SuspendableDocumentNode)
Public methodResumeSilently Resumes changed events by calling Resume for the provided suspend token, and setting the reference to the suspend token to null. All event data accumulated during the suspended state are discarded, and thus no change event is triggered even if the instance has changed during the suspended state.
(Inherited from SuspendableDocumentNodeBase)
Public methodSetDisposeInProgress Sets the flag that dispose is in progress for this node and all child nodes recursively.
(Inherited from SuspendableDocumentNode)
Protected methodSetMemberAndRaiseSelfChangedT(NullableT, NullableT) Sets a member variable of this instance and raise a change event with Empty if the new value is different from the old value. The comparison is done using the IEquatableT interface of the member variable. Note: to set members that implement IDocumentNode please use the Child... functions.
(Inherited from SuspendableDocumentNodeBase)
Protected methodSetMemberAndRaiseSelfChangedT(T, T) Sets a member variable of this instance and raise a change event with Empty if the new value is different from the old value. The comparison is done using the IEquatableT interface of the member variable. Note: to set members that implement IDocumentNode please use the Child... functions.
(Inherited from SuspendableDocumentNodeBase)
Protected methodSetMemberEnumAndRaiseSelfChangedT Sets a member variable (which is an Enum) of this instance and raise a change event with Empty if the new value is different from the old value. The comparison is done using the IEquatableT interface of the member variable. Note: to set members that implement IDocumentNode please use the Child... functions.
(Inherited from SuspendableDocumentNodeBase)
Public methodSuspendGetToken Suspend will increase the SuspendLevel.
