Constructs the event with maps for a change in one or more dimensions.

Parameters:

source - Source of the event, that is, a reference to the object that fired the event.

d - The name of the dimension of the map that is involved; null means all dimensions.

m - The map that results from the change.

t - A constant (StateChangeEvent.DATA_MAP or StateChangeEvent.METADATA_MAP) that represents the type of map state change for the query.

Parameters:

source - Source of the event, that is, a reference to the object that fired the event.

e - A constant (such as DataDirector.ROW_EDGE) that represents the edge of the map that has changed.

m - The Map object that will be applied or set.
