ContentMatch

Instances of this class represent a match state of a node type's content expression, and can be used to find out whether further content matches here, and whether a given position is a valid end of the node.

class ContentMatch {

get defaultType(): NodeType | null;

get edgeCount(): number;

readonly validEnd: boolean;

edge(n: number): MatchEdge;

fillBefore(

after: Fragment,

toEnd?: boolean,

startIndex?: number,

): Fragment | null;

findWrapping(target: NodeType): readonly NodeType[] | null;

matchFragment(

frag: Fragment,

start?: number,

end?: number,

): ContentMatch | null;

matchType(type: NodeType): ContentMatch | null;

}

§Properties

defaultType: NodeType | null readonly

[src]

Get the first matching node type at this match position that can be generated.

edgeCount: number readonly

[src]

The number of outgoing edges this node has in the finite automaton that describes the content expression.

validEnd: boolean

[src]

True when this match state represents a valid end of the node.

§Methods

edge(n: number): MatchEdge

[src]

Get the _n_th outgoing edge from this node in the finite automaton that describes the content expression.

fillBefore(after: Fragment, toEnd?: boolean, startIndex?: number): Fragment | null

[src]

Try to match the given fragment, and if that fails, see if it can be made to match by inserting nodes in front of it. When successful, return a fragment of inserted nodes (which may be empty if nothing had to be inserted). When toEnd is true, only return a fragment if the resulting match goes to the end of the content expression.

findWrapping(target: NodeType): readonly NodeType[] | null

[src]

Find a set of wrapping node types that would allow a node of the given type to appear at this position. The result may be empty (when it fits directly) and will be null when no such wrapping exists.

matchFragment(frag: Fragment, start?: number, end?: number): ContentMatch | null

[src]

Try to match a fragment. Returns the resulting match when successful.

matchType(type: NodeType): ContentMatch | null

[src]

Match a node type, returning a match after that node if successful.
