Properties

childCount int
Returns total number of child nodes in this container.
read-onlyinherited
children LinkedList<Node>
List of children.
read-onlyinherited
defaultChild LineNode
Returns an instance of default child for this container node.
read-onlyoverride
documentOffset int
Offset in characters of this node in the document.
read-onlyinherited
first Node
Returns the first child Node.
read-onlyinherited
hashCode int
The hash code for this object.
read-onlyinherited
isEmpty bool
Returns true if this container has no child nodes.
read-onlyinherited
isFirst bool
Returns true if this node is the first node in the parent list.
read-onlyinherited
isLast bool
Returns true if this node is the last node in the parent list.
read-onlyinherited
isNotEmpty bool
Returns true if this container has at least 1 child.
read-onlyinherited
last Node

read-onlyinherited
mounted bool
Returns true if this node is currently mounted, e.g. parent is not null.
read-onlyinherited
next Node?
The successor of this element in its linked list.
read-onlyinherited
offset int
Offset in characters of this node relative to parent node.
read-onlyinherited
parent ContainerNode<Node?>?
Current parent of this node. May be null if this node is not mounted.
read-onlyinherited
previous Node?
The predecessor of this element in its linked list.
read-onlyinherited
runtimeType Type
A representation of the runtime type of the object.
read-onlyinherited
style NotusStyle
Style of this node.
read-onlyinherited

Methods

inherited
optimize() → void
Optimize this node within parent.
override
remove(LineNode? node) → void
Removes node from this container.
inherited
retain(int index, int? length, NotusStyle? attributes) → void
