Inheritance is an ability of an element to transfer a pack of properties to its `children` elements 'wrapped inside'.

Inheritance is an ability of an element to transfer a pack of properties to its `children` elements 'wrapped inside'.

|
Properties, which can be inherited by objects, are `styles`, `prototypes` (if the object is a reference), `inherit` (it stands for the presence of `parent` objects), and `defaults`.
|
||||||
|
|
||||||
Properties have to be set in a specific order:
|
All values of `styles` property are contained in class `StyleSheet`, where they all are defined at `Group`s level. The `prototypes` property tree is defined in `SolidGroup` class via `PrototypeHolder` interface, and

||||||
### Main properties' inheritance:
|
`SolidReference` class helps to reuse a template object.
|
||||||
* styles
|
|
||||||
* parents
|
|
||||||
* parent's styles
|
|
||||||
* defaults
|
|
||||||
|
|
||||||
As for `prototypes`, this property has to be set after styles, but before parents. So the order will be this:
|
The order of inheritance of properties is set in function `getPropertyValue` in `VisionBase` class.
|
||||||
### Reference properties' inheritance:

The order is this:
|

* styles
|
* own styles
|

* prototypes
