Constructor Detail

### WeakGenericDynamicProperty

    public WeakGenericDynamicProperty(String propertyName,
                                      Class<?> type,
                                      Object initialValue,
                                      boolean readOnly)

Parameters:
  `propertyName` - The name of the property
  `type` - The type of the property
  `initialValue` - The initial value of the property
  `readOnly` - True for read-only property

### WeakGenericDynamicProperty

    public WeakGenericDynamicProperty(String propertyName,
                                      Class<?> type,
                                      boolean readOnly)

Parameters:
  `propertyName` - The name of the property
  `type` - The type of the property
  `readOnly` - True for read-only property

### WeakGenericDynamicProperty

    public WeakGenericDynamicProperty(String propertyName,
                                      Class<?> type,
                                      FunctionCallback initialValueGenerator,
                                      boolean readOnly)

  Variant that allows supply of a lazy-initialization function for the initial value.

  This function is called only on the first access to the property for a given object, unless the function returns null in which case it will be called again if another request is made.

  Parameters:
    `propertyName` - The name of the property
    `type` - The type of the property
    `readOnly` - True for read-only property
    `initialValueGenerator` - Callback function which will be called for initial value of property
