Usage

From source file:com.fortify.processrunner.processor.AbstractProcessorGroupByExpressions.java

/**
 * Add a new group entry. This will dynamically add the group entry
 * to the groups map if it does not yet exist. Depending on the
 * disk-backed map implementation, updated values may not be stored,
 * so we explicitly create a new value list and overwrite the existing
 * map entry./*  w w  w  . j a va  2s  . c om*/
 * @param context
 * @param key
 * @param value
 */
protected synchronized void addGroupEntry(Context context, String key, Object value) {
    Map<String, List<Object>> map = getGroupsMap(context);
    List<Object> cachedList = map.getOrDefault(key, new ArrayList<Object>());
    List<Object> newList = new ArrayList<Object>(cachedList);
    newList.add(value);
