Class SnHasBlocking

java.lang.Object
jline.api.sn.SnHasBlocking
public final class SnHasBlocking extends Object
Finite-buffer blocking or loss anywhere in the network.

Port of matlab/src/api/sn/sn_has_blocking.m. True when some station can refuse a job, either because its own buffer BINDS (Kendall's K below the population that can reach it, whatever the drop rule: WAITQ, DROP, BAS, BBS, RSRD) or because a finite capacity region caps a set of stations jointly. Such a network is not product form: the truncation couples the station occupancies, so no BCMP factorization of the equilibrium distribution exists.

Only a buffer that can actually BIND counts, which is what SnGetBufferSize decides: refreshCapacity derives a finite classcap (the chain population) at every station of every closed model, so a plain finiteness test would call every closed model blocking.

Two shapes are exempt. A Cache builds its own capped retrieval queues (classCap = 1), which the cache analyzers solve rather than treat as a buffer constraint. And the single-station M/M/1/K loss system keeps the truncated geometric distribution, a product form over its one station, evaluated in closed form by the loss branches of SolverMVA and SolverNC.
