getText method
This method returns the text for a range of characters within this input
stream. This method is guaranteed to not throw an exception if the
specified interval
lies entirely within a marked range. For more
information about marked ranges, see {@link IntStream#mark}.
@param interval an interval within the stream @return the text of the specified interval
@throws NullPointerException if interval
is null
@throws IllegalArgumentException if {@code interval.a < 0}, or if
{@code interval.b < interval.a - 1}, or if {@code interval.b} lies at or
past the end of the stream
@throws UnsupportedOperationException if the stream does not support
getting the text of the specified interval
Implementation
@override
String getText(Interval interval) {
final startIdx = min(interval.a, size);
final len = min(interval.b - interval.a + 1, size - startIdx);
return String.fromCharCodes(data, startIdx, startIdx + len);
