Class TransitionTable

java.lang.Object

org.ow2.clif.scenario.transitions.TransitionTable

All Implemented Interfaces:

java.lang.Cloneable

public class TransitionTable
extends java.lang.Object
implements java.lang.Cloneable

This class provides utilities to design a scenario, which deals with these aspects:
- Probability for the virtual user to reach a given link.
- Probability for the virtual user to click on the back button.
- Probability for the virtual user to end the session.
- Think time between each virtual user action.

The structure is a matrix that represents the probability for a virtual user to navigate from a specific page to another one.

This class need an external text file which has the following structure:

- Each value at ligne x and column y represents the probality for the virtual user, to go from the "page y" to the "page x".
It must be a value between 0 and 1.

Constructor Detail

TransitionTable

public TransitionTable(java.lang.String filename,
                       java.lang.String actions_file,
                       boolean useMatrixThinkTime,
                       boolean identifyByOrigin)

Create a transition table with specifics files and give information about how to handle think time.
In all cases, the scenario can handle its own think time in addition to one describe above.

Parameters:

filename - The transition file to load data from.

actions_file - The file containing the actions.

useMatrixThinkTime - true means that think time in the matrix are used.

identifyByOrigin - true means that the actions depends on the previous state.
