`extends Object` `implements FileVisitor<T>`

java.lang.Object
↳ | java.nio.file.SimpleFileVisitor<T>

A simple visitor of files with default behavior to visit all files and to re-throw I/O errors.

Methods in this class may be overridden subject to their general contract.

## Summary

### Protected constructors
`SimpleFileVisitor()` Initializes a new instance of this class.

### Public methods
`FileVisitResult` | `postVisitDirectory(T dir, IOException exc)` Invoked for a directory after entries in the directory, and all of their descendants, have been visited.
`FileVisitResult` | `preVisitDirectory(T dir, BasicFileAttributes attrs)` Invoked for a directory before entries in the directory are visited.
`FileVisitResult` | `visitFile(T file, BasicFileAttributes attrs)` Invoked for a file in a directory.
`FileVisitResult` | `visitFileFailed(T file, IOException exc)` Invoked for a file that could not be visited.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
From interface `java.nio.file.FileVisitor`
`abstract FileVisitResult` | `postVisitDirectory(T dir, IOException exc)` Invoked for a directory after entries in the directory, and all of their descendants, have been visited.
`abstract FileVisitResult` | `preVisitDirectory(T dir, BasicFileAttributes attrs)` Invoked for a directory before entries in the directory are visited.
`abstract FileVisitResult` | `visitFile(T file, BasicFileAttributes attrs)` Invoked for a file in a directory.
`abstract FileVisitResult` | `visitFileFailed(T file, IOException exc)` Invoked for a file that could not be visited.

## Protected constructors

### SimpleFileVisitor

    protected SimpleFileVisitor ()

Initializes a new instance of this class.

## Public methods

### postVisitDirectory

    public FileVisitResult postVisitDirectory (T dir,
                    IOException exc)

Invoked for a directory after entries in the directory, and all of their descendants, have been visited.

Unless overridden, this method returns `FileVisitResult#CONTINUE` if the directory iteration completes without an I/O exception; otherwise this method re-throws the I/O exception that caused the iteration of the directory to terminate prematurely.

Parameters
`dir` | `T`: a reference to the directory
`exc` | `IOException`: `null` if the iteration of the directory completes without an error; otherwise the I/O exception that caused the iteration of the directory to complete prematurely

Returns
`FileVisitResult` | the visit result

Throws
`IOException` |

### preVisitDirectory

    public FileVisitResult preVisitDirectory (T dir,
                    BasicFileAttributes attrs)

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

Unless overridden, this method returns `FileVisitResult#CONTINUE`.

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

Returns
`FileVisitResult` | the visit result

Throws
`IOException` |

### visitFile

    public FileVisitResult visitFile (T file,
                    BasicFileAttributes attrs)

Invoked for a file in a directory.

Unless overridden, this method returns `FileVisitResult#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
`file` | `T`: a reference to the file
`exc` | `IOException`: the I/O exception that prevented the file from being visited

Returns
`FileVisitResult` | the visit result

Throws
`IOException` |
