@ -6,10 +6,287 @@ important terms:
* `Node` - is a core thing. Node itself contains current config and its state
* `Chain` - some sequence of nodes. In one chain **only the last one** node can be active
## Nodes tree
## Work explanation
* Only the last (most deep) `node` can be `RESUMED`
* All the `chain`s of resumed `node` will have status `RESUMED`
* Only in the `chain` with status `RESUMED` there are `RESUMED` nodes
??? info Statuses
There are 3 statuses:
* New - Means that Node/Chain is just created (even before constructor) or has been fully destroyed (in context of navigation)
* Created - Means that Node/Chain is created or preparing for destroing
* Started - Means that Node/Chain is hidden and can be resumed/stopped at any time
* Resumed - Means that Node/Chain now active
In fact node will retrieve 6 changes of statuses:

### Nodes behaviour
Let's see the next sample:
```mermaid
flowchart LR
subgraph Nodes/Chains tree
NodeN1(N1)
NodeN2(N2)
class NodeN1 navigation-started;
class NodeN2 navigation-resumed;
subgraph RootChain
direction LR
NodeN1 --> NodeN2
end
class RootChain navigation-resumed;
end
```
we may say several things about the sample above:
* N2 is the latest node and it is `RESUMED`
* N1 `PAUSED`
* RootChain is `RESUMED`
So, we would like to add new node in the end of stack:
```mermaid
flowchart LR
subgraph Nodes/Chains tree
NodeN1(N1)
NodeN2(N2)
NodeN3(N3)
class NodeN1 navigation-started;
class NodeN2 navigation-started;
class NodeN3 navigation-resumed;
subgraph RootChain
direction LR
NodeN1 --> NodeN2
NodeN2 --> NodeN3
end
class RootChain navigation-resumed;
end
```
As we can see, N3 became `RESUMED` and N2 `PAUSED`. Let's try to remove N3:
```mermaid
flowchart LR
subgraph Nodes/Chains tree
NodeN1(N1)
NodeN2(N2)
class NodeN1 navigation-started;
class NodeN2 navigation-resumed;
subgraph RootChain
direction LR
NodeN1 --> NodeN2
end
class RootChain navigation-resumed;
end
```
### Chains behaviour
So, let's continue with the sample above. Let's imagine, we need to add new subchain for N2 node.
Whole tree will look like:
```mermaid
flowchart LR
subgraph Nodes/Chains tree
direction LR
NodeN1(N1)
NodeN2(N2)
NodeN3(N3)
class NodeN1 navigation-started;
class NodeN2 navigation-resumed;
class NodeN3 navigation-resumed;
subgraph RootChain
direction LR
NodeN1 --> NodeN2
NodeN2
end
NodeN2 --> N2Subchain
subgraph N2Subchain
direction LR
NodeN3
end
class RootChain navigation-resumed;
class N2Subchain navigation-resumed;
end
```
Here has been created new N2Subchain with N3 node. Both them resumed because of:
* N2 is resumed. So, N2Subchain supposed to be resumed
* Due to N2Subhain is resumed and N3 is the latest node, it will be resumed too
We may add new subchain to N1:
```mermaid
flowchart LR
subgraph Nodes/Chains tree
direction LR
NodeN1(N1)
NodeN2(N2)
NodeN3(N3)
NodeN4(N4)
class NodeN1 navigation-started;
class NodeN2 navigation-resumed;
class NodeN3 navigation-resumed;
class NodeN4 navigation-started;
subgraph RootChain
direction LR
NodeN1 --> NodeN2
NodeN2
end
NodeN1 --> N1Subchain
NodeN2 --> N2Subchain
subgraph N1Subchain
direction LR
NodeN4
end
subgraph N2Subchain
direction LR
NodeN3
end
class RootChain navigation-resumed;
class N1Subchain navigation-started;
class N2Subchain navigation-resumed;
end
```
So, it has been added, but:
* Due to N1 paused state, N1Subchain have inherited it
* Due to N1Subhain is paused, all its nodes paused too
And now we may remove N2 node. This action will trigger next changes:
```mermaid

direction TB

end
NewNodeN1 ---> NewN1Subchain
subgraph NewN1Subchain [N1Subchain]
direction TB
NewNodeN4
end
class NewRootChain navigation-resumed;
class NewN1Subchain navigation-resumed;
end
%% OldNodesChainsTree -.-> NewNodesChainsTree
OldNodeN1-.->|Become resumed| NewNodeN1
OldNodeN4-.->|Become resumed| NewNodeN4
end
```
What has happened:
1. We solved to remove N2 node. Status is changing to stopped
1. N2Subchain must be stopped
2. N3 must be stopped as well
!!! tip "Stopping in context of navigation means destroying"
