the class AbstractBytesReferenceTestCase method getSinglePageOrNull.

public static BytesRef getSinglePageOrNull(BytesReference ref) throws IOException {
    if (ref.length() > 0) {
        BytesRefIterator iterator = ref.iterator();
        BytesRef next = iterator.next();
        BytesRef retVal = next.clone();
        if (iterator.next() == null) {
            return retVal;
        }
    } else {
        return new BytesRef();
    }
    return null;
}

Example 37 with BytesRefIterator

use of org.apache.lucene.util.BytesRefIterator in project crate by crate.

the class AbstractBytesReferenceTestCase method testSliceIterator.

public void testSliceIterator() throws IOException {
    int length = randomIntBetween(10, PAGE_SIZE * randomIntBetween(2, 8));
    BytesReference pbr = newBytesReference(length);
    int sliceOffset = randomIntBetween(0, pbr.length());
    int sliceLength = randomIntBetween(0, pbr.length() - sliceOffset);
    BytesReference slice = pbr.slice(sliceOffset, sliceLength);
    BytesRefIterator iterator = slice.iterator();
    BytesRef ref = null;
    BytesRefBuilder builder = new BytesRefBuilder();
    while ((ref = iterator.next()) != null) {
        builder.append(ref);
    }
    assertArrayEquals(BytesReference.toBytes(slice), BytesRef.deepCopyOf(builder.toBytesRef()).bytes);
