Example 98 with Item

use of org.eclipse.smarthome.core.items.Item in project smarthome by eclipse.

the class AbstractRuleBasedInterpreter method getMatchingItems.

/**
 * Filters the item registry by matching each item's name with the provided name fragments.
 * The item's label and its parent group's labels are tokenizend {@link tokenize} and then altogether looked up
 * by each and every provided fragment.
 * For the item to get included into the result list, every provided fragment has to be found among the label
 * tokens.
 * If a command type is provided, the item also has to support it.
 * In case of channels and their owners being ambiguous due to sharing most of the label sequence, only the top
 * most item with support for the
 * given command type is kept.
 *
 * @param language Language information that is used for matching
 * @param labelFragments label fragments that are used to match an item's label.
 *            For a positive match, the item's label has to contain every fragment - independently of their order.
 *            They are treated case insensitive.
 * @param commandType optional command type that all items have to support.
 *            Provide {null} if there is no need for a certain command to be supported.
 * @return All matching items from the item registry.
