clone() → RootOperation
module:engine/model/operation/rootoperation~RootOperation#clone
Creates and returns an operation that has the same parameters as this operation.
Returns
RootOperation
Clone of this operation.
-
getReversed() → RootOperation
module:engine/model/operation/rootoperation~RootOperation#getReversed
Creates and returns a reverse operation. Reverse operation when executed right after the original operation will bring back tree model state to the point before the original operation execution. In other words, it reverses changes done by the original operation.
Keep in mind that tree model state may change since executing the original operation, so reverse operation will be "outdated". In that case you will need to transform it by all operations that were executed after the original operation.
Returns
RootOperation
Reversed operation.
-
toJSON() → unknown
module:engine/model/operation/rootoperation~RootOperation#toJSON
Custom toJSON method to solve child-parent circular dependencies.
Returns
unknown
Clone of this object with the operation property replaced with string.
-
Executes the operation - modifications described by the operation properties will be applied to the model tree.
Returns
void
-
internal inherited
_validate() → void
module:engine/model/operation/rootoperation~RootOperation#_validate
