- - org.apache.lucene.benchmark.byTask.utils.Algorithm

    public class Algorithm
    extends Object

Test algorithm, as read from file

### Constructor Summary

Constructors
Constructor and Description
`Algorithm(PerfRunData runData)` Read algorithm from file Property examined: alt.tasks.packages == comma separated list of alternate package names where tasks would be searched for, when not found in the default package (that of `PerfTask` `Object.getClass()`).

### Method Summary

Methods
`void` `execute()` Execute this algorithm
`ArrayList<PerfTask>` `extractTasks()` Expert: for test purposes, return all tasks participating in this algorithm.

### Constructor Detail

#### Algorithm

    public Algorithm(PerfRunData runData)
              throws Exception

Read algorithm from file Property examined: alt.tasks.packages == comma separated list of alternate package names where tasks would be searched for, when not found in the default package (that of `PerfTask` `Object.getClass()`). If the same task class appears in more than one package, the package indicated first in this list will be used.

Parameters:
  `runData` - perf-run-data used at running the tasks.
Throws:
  `Exception` - if errors while parsing the algorithm

### Method Detail

#### toString

    public String toString()

Overrides:
  `toString` in class `Object`

#### execute

    public void execute()
                 throws Exception

Execute this algorithm

Throws:
  `Exception`

#### extractTasks

    public ArrayList<PerfTask> extractTasks()

Expert: for test purposes, return all tasks participating in this algorithm.

Returns:
  all tasks participating in this algorithm.
