Field Detail

VALIDATOR_PROPERTY

static final java.lang.String VALIDATOR_PROPERTY

The validator bound property.

VALUE_PROPERTY

static final java.lang.String VALUE_PROPERTY

The value bound property.

Method Detail

getDefaultValue

V getDefaultValue()

Returns:

The default value.

getValue

V getValue()

Specified by:

getValue in interface Valued<V>

Returns:

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

setValue

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 Valued<V>

Parameters:

newValue - The new value.

Throws:

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

clearValue

void clearValue()

Determines whether the value of this model is valid.

Returns:

Whether the value of this model is valid.

validateValue

void validateValue()
                   throws ValidationException

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