Method Detail

get

public java.lang.String get(int start,
                   int end)

Description copied from interface: TextInputControl.Content

Retrieves a subset of the content.

Specified by:

get in interface TextInputControl.Content

insert

public void insert(int index,
          java.lang.String text,
          boolean notifyListeners)

Description copied from interface: TextInputControl.Content

Inserts a sequence of characters into the content.

Specified by:

insert in interface TextInputControl.Content

delete

public void delete(int start,
          int end,
          boolean notifyListeners)

Description copied from interface: TextInputControl.Content

Removes a sequence of characters from the content.

Specified by:

delete in interface TextInputControl.Content

length

public int length()

Description copied from interface: TextInputControl.Content

Returns the number of characters represented by the content.

Specified by:

length in interface TextInputControl.Content

get

public java.lang.String get()

Description copied from interface: ObservableObjectValue

Returns the current value of this ObservableObjectValue<T>.

Specified by:

get in interface ObservableObjectValue<java.lang.String>

Returns:

The current value

addListener

public void addListener(ChangeListener<? super java.lang.String> changeListener)

Description copied from interface: ObservableValue

Adds a ChangeListener which will be notified whenever the value of the ObservableValue changes. 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 ChangeListener instance may be safely registered for different ObservableValues.

The ObservableValue 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 WeakChangeListener avoid this situation.

Specified by:

addListener in interface ObservableValue<java.lang.String>

Parameters:

changeListener - The listener to register

See Also:

ObservableValue.removeListener(ChangeListener)

removeListener

public void removeListener(ChangeListener<? super java.lang.String> changeListener)

Description copied from interface: ObservableValue

Removes the given listener from the list of listeners, that are notified whenever the value of the ObservableValue changes.

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 ObservableValue<java.lang.String>

Parameters:

changeListener - The listener to remove

See Also:

ObservableValue.addListener(ChangeListener)

getValue

public java.lang.String getValue()

Description copied from interface: ObservableValue

Returns the current value of this ObservableValue

Specified by:

getValue in interface ObservableValue<java.lang.String>

Returns:

The current value

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

Observable.addListener(InvalidationListener)
