Field Details

containerObservable

protected org.eclipse.core.databinding.observable.value.IObservableValue<T> containerObservable

The observable container value that holds the bound value. Defaults to an empty writable value.

modelChangeListener

protected org.eclipse.core.databinding.observable.value.IValueChangeListener<Object> modelChangeListener

Listener that handles container value changes and updates the text control.

valueExtractor

protected Function<T,V> valueExtractor

Function that extracts the value from the container. Defaults to a function that always returns null.

nameExtractor

protected BiFunction<T,V,String> nameExtractor

Function that formats values for display with container context. Defaults to standard String.valueOf() conversion.

handler

protected BiConsumer<T,V> handler

Handler that processes new values and updates the container. Defaults to a no-op consumer.

Constructor Details

ContainerAutoCompleteTextDataBinding

public ContainerAutoCompleteTextDataBinding()

Method Details

getValue

public V getValue()

Description copied from interface: AbstractDataBinding

Gets the current value from the binding.

Specified by:

getValue in interface AbstractDataBinding<T>

Returns:

The current value of type V

doAction

public void doAction(V newNalue)

Description copied from interface: AbstractDataBinding

Performs an action when the value changes.

Specified by:

doAction in interface AbstractDataBinding<T>

Parameters:

newNalue - The new value being set

executeToTarget

public void executeToTarget()

Description copied from interface: AbstractDataBinding

Executes the binding to push data from model to UI control (target).

Specified by:

executeToTarget in interface AbstractDataBinding<T>

Overrides:

executeToTarget in class AbstractTextDataBinding<V>

executeToModel

public void executeToModel()

Description copied from interface: AbstractDataBinding

Executes the binding to pull data from UI control to model.

Specified by:

executeToModel in interface AbstractDataBinding<T>

Overrides:

executeToModel in class AbstractTextDataBinding<V>

createBinding

public void createBinding()

Description copied from interface: AbstractDataBinding

Creates and initializes the data binding.

Specified by:

createBinding in interface AbstractDataBinding<T>

Overrides:

createBinding in class AbstractAutoCompleteTextDataBinding<V>

format

protected String format(V value)

Description copied from class: AbstractAutoCompleteTextDataBinding

Formats a value for display in the auto-complete dropdown. Must be implemented by concrete subclasses.

Specified by:

format in class AbstractAutoCompleteTextDataBinding<V>

Parameters:

value - The value to format

Returns:

String representation of the value

getContainer

public org.eclipse.core.databinding.observable.value.IObservableValue<T> getContainer()

Description copied from interface: ContainerDataBinding
