Constructor Detail

FileEvent

public FileEvent(FileObject src)

Creates new FileEvent. The FileObject where the action occurred is assumed to be the same as the source object.

Parameters:

src - source file which sent this event

---

FileEvent

public FileEvent(FileObject src,
                 FileObject file)

Creates new FileEvent, specifying the action object.

Note that the two arguments of this method need not be identical in cases where it is reasonable that a different file object from the one affected would be listened to by other components. E.g., in the case of a file creation event, the event source (which listeners are attached to) would be the containing folder, while the action object would be the newly created file object.

Parameters:

src - source file which sent this event

file - FileObject where the action occurred

---

FileEvent

public FileEvent(FileObject src,
                 FileObject file,
                 boolean expected)

Creates new FileEvent, specifying the action object.

Note that the two arguments of this method need not be identical in cases where it is reasonable that a different file object from the one affected would be listened to by other components. E.g., in the case of a file creation event, the event source (which listeners are attached to) would be the containing folder, while the action object would be the newly created file object.

Parameters:

src - source file which sent this event

file - FileObject where the action occurred

expected - sets flag whether the value was expected

Method Detail

getFile

public final FileObject getFile()

Returns:

the original file where action occurred

---

getTime

public final long getTime()

The time when this event has been created.

Returns:

the milliseconds

---

isExpected

public final boolean isExpected()

Getter to test whether the change has been expected or not.

---

toString

public String toString()

Overrides:

toString in class EventObject

---

firedFrom

public boolean firedFrom(FileSystem.AtomicAction run)

Tests if FileEvent was fired from atomic action.

Parameters:

run - is tested atomic action.

Returns:

true if fired from run.

Since:

1.35
