writelnAllQ method

void writelnAllQ(Iterable objects, { String separator1 = '', String separator2 = '', QuotationMark delimiter = QuotationMark.single, })

Writes objects in sequence to the buffer.

• delimiter: Each object is followed by separator1 and enclosed with escaped quotation marks specified by delimiter.
• separator1: Optional separator String.
• separator2: Optional separator String.

Usage:

final b = StringBuffer();
b.writelnAllQ([1, 2, 3], separator1: ',', separator2: ';');
b.toString() == '\'1,\';\n'
                '\'2,\';\n'
                '\'3\'\n'

Implementation

void writelnAllQ(
  Iterable objects, {
  String separator1 = '',
  String separator2 = '',
  QuotationMark delimiter = QuotationMark.single,
}) {
  var iterator = objects.iterator;
  if (!iterator.moveNext()) return;

  if (separator1.isEmpty && separator2.isEmpty) {
    do {
      write(delimiter.symbol);
      write(iterator.current);
      write(delimiter.symbol);
      write('\n');
    } while (iterator.moveNext());
  } else {
    write(delimiter.symbol);
    write(iterator.current);
    while (iterator.moveNext()) {
      write(separator1);
      write(delimiter.symbol);
      write(separator2);
      write('\n');
      write(delimiter.symbol);
      write(iterator.current);
    }
    write(delimiter.symbol);
    write('\n');
  }
