public abstract class ValidatorProvider extends Object implements EditorProvider
|Constructor and Description|
|Modifier and Type||Method and Description|
Returns an editor for processing changes between the given two states.
Returns a validator for checking the changes between the given two root states.
@CheckForNull protected abstract Validator getRootValidator(NodeState before, NodeState after, CommitInfo info)
before- original root state
after- modified root state
info- metadata about this commit
nullif this validator is not needed for this commit
@CheckForNull public final Editor getRootEditor(NodeState before, NodeState after, NodeBuilder builder, CommitInfo info)
nullif the changes don't require processing.
An implementation of this method should generally not compare the
given before and after states, as the caller is expected to compare
the states and invoke the respective callback methods on the
Editor instance returned by this method. Instead the
implementation can use the opportunity for other preparatory work.
