Interface ISchemaMessageCommand

All Known Implementing Classes:

SchemaBag.SchemaMessageCommand

public interface ISchemaMessageCommand

Because counters in the schemabag are updated more often than the individual nodes, it is convenient not to redraw all whole schemabag visualization each time they are increased. But still, the detailed information that is invoded when the count number is requested by the user needs to be up to date. Therefore the reference to SchemaMessageCommand class is passed to the visualizer and it is used to receive latest count number each time it is requested by the user via visualizer window. This interface is created so the method getSchemaMessage can be accessed from the visualizer structures while the SchemaMessageCommand class is still in the schema package outside the visualizer structures.
