Class BackgroundThreadsRunner

java.lang.Object

com.mgnt.lifecycle.management.backgroundrunner.BackgroundThreadsRunner

public class BackgroundThreadsRunner
extends java.lang.Object

This class is part of the framework and probably will not be accessed externally. However if you use this infrastructure within Spring framework you will need to declare this class as bean in your xml configuration. The the explanation at the end of package description com.mgnt.lifecycle.management.backgroundrunner

Constructor Detail

BackgroundThreadsRunner

public BackgroundThreadsRunner()

This constructor creates an instance of this class with default pool size which is the number of tasks submitted to this BackgroundThreadsRunner. This might be fine for a small number of tasks but may be very resource-wise inefficient for larger number of tasks. If predefined pool size is needed use constructor BackgroundThreadsRunner(int)

BackgroundThreadsRunner

public BackgroundThreadsRunner(int poolSize)

This constructor creates an instance of this class with predefined pool size rather then default one. If the pool size is set to 0 or negative value or greater then the number of tasks submitted to this BackgroundThreadsRunner then the pool size will default to the number of tasks submitted to this BackgroundThreadsRunner. This might be fine for a small number of tasks but may be very resource-wise inefficient for larger number of tasks.

Parameters:

poolSize - pool size of the thread pool

BackgroundThreadsRunner

public BackgroundThreadsRunner(boolean isSelfInitializing)

This constructor is not really needed if this infrastructure is used within Spring. Because Spring will initialize this class at startup using the default constructor BackgroundThreadsRunner() or BackgroundThreadsRunner(int) provided that this class is defined as bean. But this constructor had to be added for example provided in package com.mgnt.lifecycle.management.backgroundrunner.example. Since source code in this example does not rely on Spring it has to initialize this class by itself using this constructor. However, if this infrastructure is used in some other then Spring environment which has no way of initializing this class then this constructor may be used. This constructor corresponds to BackgroundThreadsRunner()

Parameters:

isSelfInitializing -

                               int poolSize)

Method Detail

getPoolSize

public int getPoolSize()

setPoolSize

public void setPoolSize(int poolSize)

This property defines the pool size of the thread pool that runs all the tasks. If this property is not set (or set to 0 or negative value or greater then the number of tasks submitted to this BackgroundThreadsRunner) then the pool size will default to the number of tasks submitted to this BackgroundThreadsRunner. This might be fine for a small number of tasks but may be very resource-wise inefficient for larger number of tasks. Note that this property must be set before method init() is called. Otherwise it will have no effect. Also calling constructor BackgroundThreadsRunner(int) will have the same effect: it will create an instance of this class with specified size rather then default one

Parameters:

poolSize - pool size of the thread pool
