Method Details

fileSystem

AFileSystem fileSystem()

parent

ADirectory parent()

The directory (identifying container) in which this item is located and in which no other item can have the same identifier() as this item.

Returns:

the item's parent directory.

See Also:

identifier(), toPathString()

toPathString

String toPathString()

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 parent() directories and the local identifier(), but such a relation is not mandatory.

Returns:

the item's globally unique identifier.

See Also:

parent(), identifier()

toPath

String[] toPath()

identifier

String identifier()

The value that uniquely identifies the item locally in its parent() directory.

Note that this value might be a combination of #name() and #type(), but such a relation is not mandatory.

Returns:

the item's locally unique identifier.

See Also:

parent(), toPathString(), #name(), #type()

exists

boolean exists()

Queries whether the item represented by this instance actually physically exists on the underlying storage layer.

Returns:

whether the item exists.

defaultSeparator

static char defaultSeparator()

buildItemPath

static String[] buildItemPath(AItem item)

assembleDebugString

static VarString assembleDebugString(AItem item, VarString vs)

actual

static AItem actual(AItem item)
