onChange

public void onChange(@NotNull
 @NotNull List<ResourceChange> changes)

Description copied from interface: ResourceChangeListener

Report resource changes based on the filter properties of this listener.

Note that resource changes for paths which are ancestors of the paths this listener was registered to may be reported through this method. This is due to limitations of certain resource providers to provide events on a more granular level (e.g. for deletion or movement of resources containing (potentially nested) child resources).

Starting with version 1.2 of this API, an instance of ResoureChangeList is passed as the parameter to allow passing additional information.

Specified by:

onChange in interface ResourceChangeListener

Parameters:

changes - The changes list. This list is immutable.
