public class MaterializerState
extends Object

Debug utility to dump the running streams of a materializers in a structure describing the graph layout and "waits-on" relationships.

Some of the data extracted may be off unless the stream has settled, for example in when deadlocked, but the structure should be valid regardless. Extracting the information often will have an impact on the performance of the running streams.
