Class Ret.EventResult

java.lang.Object

jline.io.Ret.EventResult

Enclosing class:

Ret

public static class Ret.EventResult
extends Object

Result type for event-based state space exploration functions.

This class encapsulates the output of afterEvent* functions which compute the possible states reachable after an event occurs in the queueing network, along with the rates and probabilities of transitions.

Field Summary

Fields

Modifier and Type	Field	Description
final Matrix	outpreempt	PREEMPT annotation of each successor: outpreempt(i,r) counts the class-r jobs pushed back into the buffer on successor row i.
final Matrix	outprob
final Matrix	outrate
final Matrix	outspace
final Matrix	outstart	START annotation of each successor: outstart(i,r) counts the class-r jobs that begin, or resume, holding a server on successor row i.

Method Summary

Modifier and Type	Method	Description
double	preemptOf(int row, int cls)	PREEMPT count of one successor row and class.
double	startOf(int row, int cls)	START count of one successor row and class, zero when the arc carries no annotation.

Field Details

outspace

public final Matrix outspace

outrate

public final Matrix outrate

outprob

public final Matrix outprob

outstart

public final Matrix outstart

START annotation of each successor: outstart(i,r) counts the class-r jobs that begin, or resume, holding a server on successor row i. Instantaneous tag on an existing arc, never an event of its own, so nothing here changes a rate, a probability or a state.

outpreempt

public final Matrix outpreempt

PREEMPT annotation of each successor: outpreempt(i,r) counts the class-r jobs pushed back into the buffer on successor row i.

 Matrix outpreempt)

Method Details

startOf

public double startOf(int row,
 int cls)

START count of one successor row and class, zero when the arc carries no annotation. Reading the matrices through this accessor keeps every caller safe against a handler that has not been annotated.

preemptOf

public double preemptOf(int row,
 int cls)

PREEMPT count of one successor row and class.
