JsonFileBasedLoader

public JsonFileBasedLoader(JacksonObjectMapper objectMapper,
                           Class<T> type)

Method Detail

findByObjectId

public List<T> findByObjectId(Path directory,
                              String objectId)
                       throws IOException

Description copied from interface: Loader

Find all the objects which contain an object id. Each object (widget, page, ...) has its own id. To increase performances, we just search if the id is in the text files. Only files which contain a reference are deserialized

Throws:

IOException

findByObjectIds

public Map<String,List<T>> findByObjectIds(Path directory,
                                           List<String> objectIds)
                                    throws IOException

Description copied from interface: Loader

Returns a Map of object ids, with all the objects which contain an object id. Each object (widget, page, ...) has its own id. To increase performances, we just search if the id is in the text files. Only files which contain a reference are deserialized

Throws:

IOException

getByUUID

public T getByUUID(Path directory,
                   String uuid)
            throws IOException

Throws:

contains

public boolean contains(Path directory,
                        String objectId)
                 throws IOException

indexOf

protected int indexOf(byte[] file,
                      byte[] occurence)

Returns the start position of the first occurrence of the specified target within array, or -1 if there is no such occurrence.
