Example 1 with BridgeImpl

use of org.eclipse.smarthome.core.thing.internal.BridgeImpl in project smarthome by eclipse.

the class ThingHelper method merge.

/**
 * Merges the content of a ThingDTO with an existing Thing.
 * Where ever the DTO has null values, the content of the original Thing is kept.
 * Where ever the DTO has non-null values, these are used.
 * In consequence, care must be taken when the content of a list (like configuration, properties or channels) is to
 * be updated - the DTO must contain the full list, otherwise entries will be deleted.
 *
 * @param thing the Thing instance to merge the new content into
 * @param updatedContents a DTO which carries the updated content
 * @return A Thing instance, which is the result of the merge
