Examples with OffsetSpan com.amazon.ion.OffsetSpan used on opensource projects

Example 1 with OffsetSpan

use of com.amazon.ion.OffsetSpan in project ion-java by amzn.

the class RawValueSpanReaderTest method generateSpan.

private SpanTester generateSpan(Object expected, IonType type) {
    // This span includes the TID and length bytes
    Span span = seekableReader.currentSpan();
    // This gets just the value bytes
    byte[] expectedBytes = valueBytes((OffsetSpan) spanProvider.valueSpan());
    return new SpanTester(expected, type, expectedBytes, span);
}
