Class ContainerBooleanDataBinding<T>

java.lang.Object

com.amalgamasimulation.desktop.binding.widgets.AbstractBooleanDataBinding

com.amalgamasimulation.desktop.binding.widgets.ContainerBooleanDataBinding<T>

Type Parameters:

T - The type of the container object

All Implemented Interfaces:

AbstractDataBinding<Boolean>, ContainerDataBinding<T,Boolean>

Direct Known Subclasses:

EmfBooleanDataBinding

public class ContainerBooleanDataBinding<T>
extends AbstractBooleanDataBinding
implements ContainerDataBinding<T,Boolean>

A specialized boolean data binding implementation that works with container objects. Extends AbstractBooleanDataBinding and implements ContainerDataBinding to provide container-aware boolean binding functionality.

Field Details

containerObservable

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

The observable container value that holds the boolean state. 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 checkbox state.

valueExtractor

protected Function<T,Boolean> valueExtractor

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

handler

protected BiConsumer<T,Boolean> handler

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

Constructor Details

ContainerBooleanDataBinding

public ContainerBooleanDataBinding()

Method Details

valueExtractor

public ContainerBooleanDataBinding<T> valueExtractor(Function<T,Boolean> valueExtractor)

Sets the value extractor function that gets the boolean state from the container.

Parameters:

valueExtractor - The function to extract the boolean value

Returns:

this binding instance for method chaining

handler

public ContainerBooleanDataBinding<T> handler(BiConsumer<T,Boolean> handler)

Sets the handler function that updates the container with new boolean values.

Parameters:

handler - The function to handle container updates

Returns:

this binding instance for method chaining

containerObservable

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

Sets the observable container instance.

Parameters:

containerObservable - The observable container value

Returns:

this binding instance for method chaining

getContainer

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

Description copied from interface: ContainerDataBinding

Gets the observable container that holds the bound value.

Specified by:

getContainer in interface ContainerDataBinding<T,Boolean>

Returns:

An IObservableValue representing the container object. The container itself is observable and will notify listeners of changes.

getValue

public Boolean 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(Boolean 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 AbstractBooleanDataBinding

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 AbstractBooleanDataBinding

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 AbstractBooleanDataBinding
