Class GeneratedPropertyContainer.GeneratedProperty<T>

Constructor Detail

• GeneratedProperty

  public GeneratedProperty​(Item item,
                           Object propertyId,
                           Object itemId,
                           PropertyValueGenerator<T> generator)

Method Detail

• getValue

  public T getValue()

  Description copied from interface: Property

  Gets the value stored in the Property. The returned object is compatible with the class returned by getType().

  Specified by:

  getValue in interface Property<T>

  Returns:

  the value stored in the Property

• setValue

  public void setValue​(T newValue)
                throws Property.ReadOnlyException

  Description copied from interface: Property

  Sets the value of the Property.

  Implementing this functionality is optional. If the functionality is missing, one should declare the Property to be in read-only mode and throw Property.ReadOnlyException in this function.

  Note : Since Vaadin 7.0, setting the value of a non-String property as a String is no longer supported.

  Specified by:

  setValue in interface Property<T>

  Parameters:

  newValue - New value of the Property. This should be assignable to the type returned by getType

  Throws:

  Property.ReadOnlyException - if the object is in read-only mode

• getType

  public Class<? extends T> getType()

  Description copied from interface: Property

  Returns the type of the Property. The methods getValue and setValue must be compatible with this type: one must be able to safely cast the value returned from getValue to the given type and pass any variable assignable to this type as an argument to setValue.

  Specified by:

  getType in interface Property<T>

  Returns:

  type of the Property

• isReadOnly

  public boolean isReadOnly()

  Description copied from interface: Property

  Tests if the Property is in read-only mode. In read-only mode calls to the method setValue will throw ReadOnlyException and will not modify the value of the Property.

  Specified by:

  isReadOnly in interface Property<T>

  Returns:

  true if the Property is in read-only mode, false if it's not

• setReadOnly

  public void setReadOnly​(boolean newStatus)

  Description copied from interface: Property

  Sets the Property's read-only mode to the specified status. This functionality is optional, but all properties must implement the isReadOnly mode query correctly.

  Specified by:

  setReadOnly in interface Property<T>

  Parameters:

  newStatus - new read-only status of the Property
