Usage

From source file:org.springframework.integration.config.IntegrationRegistrar.java

/**
 * This method will auto-register a ChannelInitializer which could also be overridden by the user
 * by simply registering a ChannelInitializer {@code <bean>} with its {@code autoCreate} property
 * set to false to suppress channel creation.
 * It will also register a ChannelInitializer$AutoCreateCandidatesCollector
 * which simply collects candidate channel names.
 * @param registry The {@link BeanDefinitionRegistry} to register additional {@link BeanDefinition}s.
