Method Detail

apply

                          ChangeContext context)
                   throws OperationException

Description copied from interface: Operation

Derives the new grid state from the current grid state. Executing this method should be quick (even on large datasets) since it is expected to just derive the new grid from the existing one without actually executing any expensive computation. Long-running computations should rather go in the derivation of a ChangeData which will be fetched asynchronously.

Parameters:

projectState - the state of the grid before the change

Returns:

an object which bundles up various pieces of information produced by the operation: primarily, the new grid after applying the operation. This object can be subclassed to expose more information, which should be serializable with Jackson so that it reaches the frontend.

Throws:

OperationException - when the change cannot be applied to the given grid

getDescription

public String getDescription()

Description copied from interface: Operation

A short human-readable description of what this operation does.
