Examples with ConfigurationManager org.infinispan.configuration.ConfigurationManager used on opensource projects

Example 1 with ConfigurationManager

use of org.infinispan.configuration.ConfigurationManager in project indy by Commonjava.

the class CacheProducer method mergedCachesFromConfig.

/**
 * For the ISPN merging, we should involve at least two different xml config scopes here,
 * one is from indy self default resource xml, another one is from customer's config xml.
 *
 * To prevent the error of EmbeddedCacheManager instances configured with same JMX domain,
 * ISPN should enable 'allowDuplicateDomains' attribute for per GlobalConfigurationBuilder build,
 * that will cost more price there for DefaultCacheManager construct and ConfigurationBuilder build.
 *
 * Since what we need here is simply parsing xml inputStreams to the defined configurations that ISPN
 * could accept, then merging the two stream branches into a entire one.
 * What classes this method uses from ISPN are:
 * {@link ConfigurationBuilderHolder}
 * {@link ParserRegistry}
 * {@link ConfigurationManager}
 *
 * @param cacheMgr
 * @param config
 * @param path
