Example 2 with LRUCacheConfiguration

the class DefaultOfficeResourceViewer method initialize.

@Override
public void initialize() throws InitializationException {
    try {
        LRUCacheConfiguration attachmentConfig = new LRUCacheConfiguration(MODULE_NAME + ".attachment", 50);

Example 3 with LRUCacheConfiguration

use of org.xwiki.cache.config.LRUCacheConfiguration in project xwiki-platform by xwiki.

the class CacheMacro method getContentCache.

/**
 * Get a cache matching the passed time to live and max entries.
 * <p>
 * Note that whenever a new cache is created it currently means a new thread is used too (since the JBoss cache used
 * underneath uses a thread for evicting entries from the cache). We need to modify our xwiki-cache module to allow
 * setting time to live on cache items, see https://jira.xwiki.org/browse/XWIKI-5907
 * </p>
 *
 * @param lifespan the number of seconds to cache the content
 * @param maxEntries the maximum number of entries in the cache (Least Recently Used entries are ejected)
 * @return the matching cache (a new cache is created if no existing one is found)
 * @throws MacroExecutionException in case we fail to create the new cache
