AbstractEditValueControl

public abstract class AbstractValueControl<V>
extends AbstractControl
implements ValueControl<V>

Constructor Detail

AbstractValueControl

public AbstractValueControl(InfoModel infoModel,
                            ValueModel<V> valueModel,
                            Enableable enableable)

Info model, value model, and enableable constructor.

Parameters:

infoModel - The component info model.

valueModel - The component value model.

enableable - The enableable object in which to store enabled status.

Throws:

java.lang.NullPointerException - if the given info model, value model, and/or enableable object is null.

Method Detail

getValueModel

protected ValueModel<V> getValueModel()

Returns:

The value model used by this component.

determineValid

protected boolean determineValid()

Checks the state of the component for validity. This version checks the validity of the value model. This version performs no additional checks if the control is disabled.

Overrides:

determineValid in class AbstractComponent

Returns:

true if the component and all children passes all validity tests, else false.

validate

public boolean validate()

Validates the user input of this component and all child components. The component will be updated with error information. This version validates the associated value model. This version performs no additional checks if the control is disabled.

Specified by:

validate in interface Component

Overrides:

validate in class AbstractComponent

Returns:

The current state of AbstractComponent.isValid() as a convenience.

reset

public void reset()

Resets the control to its default value. This version resets the control value.

Specified by:

reset in interface Control

Overrides:

reset in class AbstractControl

See Also:

resetValue()

getDefaultValue

public V getDefaultValue()

Specified by:

getDefaultValue in interface ValueModel<V>

Returns:

The default value.

getValue

public V getValue()

Specified by:

getValue in interface ValuedComponent<V>

Specified by:

getValue in interface Valued<V>

Specified by:

getValue in interface ValueModel<V>

Returns:

The input value, or null if there is no input value.

setValue

public void setValue(V newValue)
              throws java.beans.PropertyVetoException

Sets the new value. This is a bound property that only fires a change event when the new value is different via the equals() method. If a validator is installed, the value will first be validated before the current value is changed. Validation always occurs if a validator is installed, even if the value is not changing. If the value change is vetoed by the installed validator, the validation exception will be accessible via Throwable.getCause().

Specified by:

setValue in interface ValuedComponent<V>

Specified by:

setValue in interface Valued<V>

Specified by:

setValue in interface ValueModel<V>

Parameters:

newValue - The new value.

Throws:

java.beans.PropertyVetoException - if the provided value is not valid or the change has otherwise been vetoed.

See Also:

getValidator(), ValueModel.VALUE_PROPERTY

clearValue

public void clearValue()

Clears the value by setting the value to null, which may be invalid according to any installed validators. No validation occurs.

Specified by:

clearValue in interface ValueModel<V>

See Also:

Value#VALUE_PROPERTY

resetValue

public void resetValue()

Resets the value to a default value, which may be invalid according to any installed validators. No validation occurs.

Specified by:

resetValue in interface ValueModel<V>

See Also:

ValueModel.VALUE_PROPERTY

getValidator

public Validator<V> getValidator()

Specified by:

getValidator in interface ValueModel<V>

Returns:

The validator for this model, or null if no validator is installed.

setValidator

public void setValidator(Validator<V> newValidator)

Sets the validator. This is a bound property

Specified by:

setValidator in interface ValueModel<V>

Parameters:

newValidator - The validator for this model, or null if no validator should be used.

See Also:

ValueModel.VALIDATOR_PROPERTY

isValidValue

public boolean isValidValue()

Determines whether the value of this model is valid.

Specified by:

isValidValue in interface ValueModel<V>

Returns:

Whether the value of this model is valid.

validateValue

public void validateValue()
                   throws ValidationException

Validates the value of this model, throwing an exception if the model is not valid.

Specified by:

validateValue in interface ValueModel<V>

Throws:

ValidationException - if the value of this model is not valid.

getValueClass

public java.lang.Class<V> getValueClass()

Specified by:

getValueClass in interface ValuedComponent<V>

Specified by:

getValueClass in interface ValueModel<V>

Returns:

The class representing the type of value this model can hold.
