PiWriter

An object that implements PiWriter is able to build a string representation of a node in the AST.

If you want to write your own unparser/writer you will need to implement this interface.

/* File: core/src/writer/PiWriter.ts */

export interface PiWriter {

	/**
	 * Returns a string representation of 'modelelement'.
	 * If 'short' is present and true, then a single-line result will be given.
	 * Otherwise, the result is always a multi-line string.
	 * Note that the single-line-string cannot be parsed into a correct model.
	 *
	 * @param modelelement
	 * @param startIndent
	 * @param short
	 */
	writeToString(modelelement: PiElement, startIndent?: number, short?: boolean): string;

	/**
	 * Returns a string representation of 'modelelement', divided into an array of strings,
	 * each of which contain a single line (without newline).
	 * If 'short' is present and true, then a single-line result will be given.
	 * Otherwise, the result is always a multi-line string.
	 *
	 * @param modelelement
	 * @param startIndent
	 * @param short
	 */
	writeToLines(modelelement: PiElement, startIndent?: number, short?: boolean): string[];

	/**
	 * Returns the name of 'modelelement' if it has one, else returns
	 * a short unparsing of 'modelelement'.
	 * Used by the validator to produce readable error messages.
	 *
	 * @param modelelement
	 */
	writeNameOnly(modelelement: PiElement): string;
