Constructor
| Name | Description |
|---|---|
| new Changeset(transaction, owner) Abstract | Creates an empty |
Members
| Name | Description |
|---|---|
base : Protected | If a method has been overridden, then the base method provides access to the overridden method. |
hasChanges : Abstract | Gets a value that indicates if this changeset contains any changes, whether they are primitive or in contained changesets. |
isReadOnly : | Gets a value that indicates if the changeset is in a read-only state and can no longer be modified. |
owner : | Gets the container where the changes take place. |
ownerVersion : | Gets the version of the owner at the time when the changeset was created. |
transaction : | Gets the owning transaction. |
transactionVersion : | Gets the transaction version of this changeset. |
transactionVersionLocal : | Gets the local transaction version of this changeset. |
type : Abstract | Gets the type of change. |
Methods
| Name | Description |
|---|---|
| __onChildTxnVersionDirty() | Called by a child changeset when its version changes or becomes dirty. |
| _apply(target) Abstract Protected | Applies any local primitive changes. |
| _assertWritable() Protected | Throws an error if the changeset is read-only. |
| _clearChanges() Abstract Protected | Actually removes all changes from this changeset. |
| _clearChangesRecursive(parentChangeset) Protected | Called by a parent changeset on its child changeset, this, for it to clear its changes. |
| _resetNetOrder() Protected | Resets the topological order of this changeset, and of any child changesets, by calculating it based on its current parents. |
| _setTransactionVersion(txnVersion, noNotifyParentChangeset) Protected | Updates the transaction version to a given value, if it is greater than the current one. Notifies all parents, except the optionally specified one, that their version is dirty. |
| _setTransactionVersionLocal(txnVersionLocal, noNotifyParentChangeset) Protected | Updates the local transaction version to a given value due to a local, primitive change, if it is greater than the current one. Then, it calls |
| clearChanges() | Removes all changes from this changeset. |
| eachChildChangeset(fun, ctx) Abstract | Calls a function once per child changeset. |
extend(source, keyArgs) : Object | Extend an object with the properties of another. |
