Class PoolFiller

java.lang.Object

gate.util.spring.xml.PoolFiller

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean

public class PoolFiller
extends Object
implements org.springframework.beans.factory.InitializingBean

Simple bean that takes a pooled target source and performs a sequence of n getTarget calls followed by n releaseTarget calls. This has the effect of pre-populating the pool with n instances up-front (normally a pooled target source only creates objects the first time they are required). Note that if the specified number of instances is greater than the maximum size of the pool the number of calls will be reduced accordingly.
