Class AbstractTypeAwareSupport.BeansOfTypeTargetSource

java.lang.Object

org.springframework.plugin.core.support.AbstractTypeAwareSupport.BeansOfTypeTargetSource

All Implemented Interfaces:

org.springframework.aop.TargetClassAware, org.springframework.aop.TargetSource

Enclosing class:

AbstractTypeAwareSupport<T>

static class AbstractTypeAwareSupport.BeansOfTypeTargetSource
extends java.lang.Object
implements org.springframework.aop.TargetSource

TargetSource implementation that returns all beans of the configured type from the ListableBeanFactory the instance was set up with. Allows freezing the lookup as calls to ListableBeanFactory.getBeansOfType(Class, boolean, boolean) are potentially expensive as the entire factory has to be scanned for type information.
