Public methods

postVisitDirectory

Added in API level 26

public FileVisitResult postVisitDirectory (T dir, 
                IOException exc)

Returns
`FileVisitResult`	the visit result

Throws
`IOException`

preVisitDirectory

Added in API level 26

public FileVisitResult preVisitDirectory (T dir, 
                BasicFileAttributes attrs)

Invoked for a directory before entries in the directory are visited.

Unless overridden, this method returns CONTINUE.

Parameters
`dir`	`T`: a reference to the directory
`attrs`	`BasicFileAttributes`: the directory's basic attributes

Returns
`FileVisitResult`	the visit result

Throws
`IOException`

visitFile

Added in API level 26

public FileVisitResult visitFile (T file, 
                BasicFileAttributes attrs)

Invoked for a file in a directory.

Unless overridden, this method returns CONTINUE.

Parameters
`file`	`T`: a reference to the file
`attrs`	`BasicFileAttributes`: the file's basic attributes

Returns
`FileVisitResult`	the visit result

Throws
`IOException`

visitFileFailed

public FileVisitResult visitFileFailed (T file, 
                IOException exc)

Invoked for a file that could not be visited.

Unless overridden, this method re-throws the I/O exception that prevented the file from being visited.

Parameters
