EmbedNode class

An embed node inside of a line in a Notus document.

Embed node is a leaf node similar to TextNode. It represents an arbitrary piece of non-text content embedded into a document, such as, image, horizontal rule, video, or any other object with defined structure, like tweet, for instance.

Embed node's length is always 1 character and it is represented with zero-width space in the document text.

Any inline style can be applied to an embed, however this does not necessarily mean the embed will look according to that style. For instance, applying "bold" style to an image gives no effect, while adding a "link" to an image actually makes the image react to user's action.

Methods

applyAttribute(NotusAttribute attribute) → void
Applies style attribute to this node.
inherited
applyStyle(NotusStyle value) → void
Applies new style value to this node. Provided value is merged into current style.
inherited
clearStyle() → void
Clears style of this node.
inherited
containsOffset(int offset) → bool
Returns true if this node contains character at specified offset in the document.
inherited
cutAt(int index) → LeafNode?
Cuts a leaf node from index to the end of this node and returns new node in detached state (e.g. mounted returns false).
inherited
delete(int index, int? length) → void
Delete length characters of this node starting from index.
inherited
formatAndOptimize(NotusStyle? style) → void
Formats this node and optimizes it with adjacent leaf nodes if needed.
inherited
insert(int index, String value, NotusStyle? style) → void
Insert text at specified character index with style style.
inherited
insertAfter(Node entry) → void
Insert an element after this element in this element's linked list.
inherited
insertBefore(Node entry) → void
Insert an element before this element in this element's linked list.
inherited
isolate(int index, int length) → LeafNode
Isolates a new leaf node starting at index with specified length.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
optimize() → void
Optimizes this text node by merging it with adjacent nodes if they share the same style.
inherited
retain(int index, int? length, NotusStyle? style) → void
Format length characters of this node starting from index with specified style style.
inherited
splitAt(int index) → LeafNode?
Splits this leaf node at index and returns new node.
inherited
toDelta() → Delta
Returns Delta representation of this node.
inherited
toPlainText() → String
Returns plain-text representation of this node.
inherited
toString() → String
A string representation of this object.
inherited
Unlink the element from its linked list.
