Methods

Method	Alerts	Return Type	Description
annotateMarker(marker, props)	Alpha	void	Annotates the marker with the provided properties.
getMarkerFromId(id)	Alpha	ISegment | undefined	Looks up and returns a Marker using its id. Returns undefined if there is no marker with the provided id in this SharedString.
getText(start, end)	Alpha	string	Retrieve text from the SharedString in string format.
getTextRangeWithMarkers(start, end)	Alpha	string
getTextWithPlaceholders(start, end)	Alpha	string	Adds spaces for markers and handles, so that position calculations account for them.
insertMarker(pos, refType, props)	Alpha	void	Inserts a marker at the position.
insertMarkerRelative(relativePos1, refType, props)	Alpha	void	Inserts a marker at a relative position.
insertText(pos, text, props)	Alpha	void	Inserts the text at the position.
insertTextRelative(relativePos1, text, props)	Alpha	void	Inserts the text at the position.
removeText(start, end)	Alpha	void	Removes the text in the given range.
replaceText(start, end, text, props)	Alpha	void	Replaces a range with the provided text.
searchForMarker(startPos, markerLabel, forwards)	Alpha	Marker | undefined	Searches a string for the nearest marker in either direction to a given start position. The search will include the start position, so markers at the start position are valid results of the search.
