Methods

Modifier and Type	Method and Description
boolean	addAll(java.lang.CharSequence... paragraphs) A convenient method for var-arg adding of elements.
boolean	addAll(java.util.Collection<? extends java.lang.CharSequence> paragraphs)
void	addListener(InvalidationListener listener) Adds an InvalidationListener which will be notified whenever the Observable becomes invalid.
void	addListener(ListChangeListener<? super java.lang.CharSequence> listener) Add a listener to this observable list.
java.lang.CharSequence	get(int index)
void	remove(int from, int to) Basically a shortcut to sublist(from, to).clear() As this is a common operation, ObservableList has this method for convenient usage.
boolean	removeAll(java.lang.CharSequence... elements) A convenient method for var-arg usage of removaAll method.
void	removeListener(InvalidationListener listener) Removes the given listener from the list of listeners, that are notified whenever the value of the Observable becomes invalid.
void	removeListener(ListChangeListener<? super java.lang.CharSequence> listener) Tries to removed a listener from this observable list.
boolean	retainAll(java.lang.CharSequence... elements) A convenient method for var-arg usage of retain method.
boolean	setAll(java.lang.CharSequence... paragraphs) Clears the ObservableList and add all the elements passed as var-args.
boolean	setAll(java.util.Collection<? extends java.lang.CharSequence> paragraphs) Clears the ObservableList and add all elements from the collection.
int	size()

Method Detail

get

public java.lang.CharSequence get(int index)

Specified by:

get in interface java.util.List<java.lang.CharSequence>

Specified by:

get in class java.util.AbstractList<java.lang.CharSequence>

addAll

public boolean addAll(java.util.Collection<? extends java.lang.CharSequence> paragraphs)

Specified by:

addAll in interface java.util.Collection<java.lang.CharSequence>

Specified by:

addAll in interface java.util.List<java.lang.CharSequence>

Overrides:

addAll in class java.util.AbstractCollection<java.lang.CharSequence>

addAll

public boolean addAll(java.lang.CharSequence... paragraphs)

Description copied from interface: ObservableList

A convenient method for var-arg adding of elements.

Specified by:

addAll in interface ObservableList<java.lang.CharSequence>

Parameters:

paragraphs - the elements to add

Returns:

true (as specified by Collection.add(E))

setAll

public boolean setAll(java.util.Collection<? extends java.lang.CharSequence> paragraphs)

Description copied from interface: ObservableList

Clears the ObservableList and add all elements from the collection.

Specified by:

setAll in interface ObservableList<java.lang.CharSequence>

Parameters:

paragraphs - the collection with elements that will be added to this observableArrayList

Returns:

true (as specified by Collection.add(E))

setAll

public boolean setAll(java.lang.CharSequence... paragraphs)

Description copied from interface: ObservableList

Clears the ObservableList and add all the elements passed as var-args.

Specified by:

setAll in interface ObservableList<java.lang.CharSequence>

Parameters:

paragraphs - the elements to set

Returns:

true (as specified by Collection.add(E))

size

public int size()

Specified by:

size in interface java.util.Collection<java.lang.CharSequence>

Specified by:

size in interface java.util.List<java.lang.CharSequence>

Specified by:

size in class java.util.AbstractCollection<java.lang.CharSequence>

addListener

public void addListener(ListChangeListener<? super java.lang.CharSequence> listener)

Description copied from interface: ObservableList

Add a listener to this observable list.

Specified by:

addListener in interface ObservableList<java.lang.CharSequence>

Parameters:

listener - the listener for listening to the list changes

removeListener

public void removeListener(ListChangeListener<? super java.lang.CharSequence> listener)

Description copied from interface: ObservableList

Tries to removed a listener from this observable list. If the listener is not attached to this list, nothing happens.

Specified by:

removeListener in interface ObservableList<java.lang.CharSequence>

Parameters:

listener - a listener to remove

removeAll

public boolean removeAll(java.lang.CharSequence... elements)

Description copied from interface: ObservableList

A convenient method for var-arg usage of removaAll method.

Specified by:

removeAll in interface ObservableList<java.lang.CharSequence>

Parameters:

elements - the elements to be removed

Returns:

true if list changed as a result of this call

retainAll

public boolean retainAll(java.lang.CharSequence... elements)

Description copied from interface: ObservableList

A convenient method for var-arg usage of retain method.

Specified by:

retainAll in interface ObservableList<java.lang.CharSequence>

Parameters:

elements - the elements to be retained

Returns:

true if list changed as a result of this call

remove

public void remove(int from,
          int to)

Description copied from interface: ObservableList

Basically a shortcut to sublist(from, to).clear() As this is a common operation, ObservableList has this method for convenient usage.

Specified by:

remove in interface ObservableList<java.lang.CharSequence>

Parameters:

from - the start of the range to remove (inclusive)

to - the end of the range to remove (exclusive)

addListener

public void addListener(InvalidationListener listener)

Description copied from interface: Observable

Adds an InvalidationListener which will be notified whenever the Observable becomes invalid. If the same listener is added more than once, then it will be notified more than once. That is, no check is made to ensure uniqueness.

Note that the same actual InvalidationListener instance may be safely registered for different Observables.

The Observable stores a strong reference to the listener which will prevent the listener from being garbage collected and may result in a memory leak. It is recommended to either unregister a listener by calling removeListener after use or to use an instance of WeakInvalidationListener avoid this situation.

Specified by:

addListener in interface Observable

Parameters:

listener - The listener to register

See Also:

Observable.removeListener(InvalidationListener)

removeListener

public void removeListener(InvalidationListener listener)

Description copied from interface: Observable

Removes the given listener from the list of listeners, that are notified whenever the value of the Observable becomes invalid.

If the given listener has not been previously registered (i.e. it was never added) then this method call is a no-op. If it had been previously added then it will be removed. If it had been added more than once, then only the first occurrence will be removed.

Specified by:

removeListener in interface Observable

Parameters:

listener - The listener to remove

See Also:

Observable.addListener(InvalidationListener)
