Method Details

toPathString

default String toPathString()

Description copied from interface: AItem

The value that uniquely identifies the item globally in the whole file system.

Note that this value is usually a combination of the identifiers of AItem.parent() directories and the local AItem.identifier(), but such a relation is not mandatory.

Specified by:

toPathString in interface AItem

Returns:

the item's globally unique identifier.
