Method Detail

execute

@Nonnull
public final java.lang.Object execute(@Nonnull
                                      EditableImage image,
                                      @Nonnull
                                      java.lang.Object model)

Executes this operation on the given model.

Parameters:

model - the image representation

canHandle

public boolean canHandle(@Nonnull
                         Op operation)

Sometimes an implementation can't handle a specific set of parameters. In this case, this method must return false, so this implementation will be discarded. This method returns true by default, so subclasses with different behaviours should override it.

bind

protected void bind(@Nonnull
                    Op operation)

execute

@Nonnull
protected abstract Model execute(@Nonnull
                                 Op operation,
                                 @Nonnull
                                 EditableImage image,
                                 @Nonnull
                                 Model model)

The concrete implementation of this operation should be provided by overriding this method.

Parameters:

operation - the operation to implement

model - the image representation
