Method Detail

getProperty

Property<E> getProperty()

Get the property to which the value is bound.

Returns:

the property

getModelValue

Object getModelValue()

Get the model value.

Returns:

The constant expression value, converted to model type if a PropertyValueConverter is available.

getModelType

default Class<?> getModelType()

Get the model type.

Returns:

The constant expresion type, using the model type if a PropertyValueConverter is available.

create
