ContainerNode<T extends Node> class

Container node can accommodate other nodes.

Delegates insert, retain and delete operations to children nodes. For each operation container looks for a child at specified index position and forwards operation to that child.

Most of the operation handling logic is implemented by LineNode and TextNode.

read-only
children LinkedList<Node>
List of children.
read-only
defaultChild → T
Returns an instance of default child for this container node. [...]
read-only
documentOffset int
Offset in characters of this node in the document.
read-only, inherited
first Node
Returns the first child Node.
read-only
hashCode int
The hash code for this object. [...]
read-only, inherited
isEmpty bool
Returns true if this container has no child nodes.
read-only
isFirst bool
Returns true if this node is the first node in the parent list.
read-only, inherited

next Node
Return the successor of this element in its linked list. [...]
read-only, inherited
offset int
Offset in characters of this node relative to parent node. [...]
read-only, inherited
parent ContainerNode<Node>
Current parent of this node. May be null if this node is not mounted.
read-only, inherited
previous Node
