Robert Scholte moved MNGSITE-382 to LUCENE-9052:
------------------------------------------------
Key: LUCENE-9052 (was: MNGSITE-382)
Lucene Fields: New
Workflow: patch-available, re-open possible, new labels (was: Default
workflow, editable Closed status)
Project: Lucene - Core (was: Maven Project Web Site)
> Deprecated method copyChars is used in example
> ----------------------------------------------
>
> Key: LUCENE-9052
> URL: https://issues.apache.org/jira/browse/LUCENE-9052
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: gitesh
> Priority: Minor
>
> Following documentation page for FST class has some example code.
> [https://lucene.apache.org/core/8_3_0/core/org/apache/lucene/util/fst/package-summary.html]
> {code:java}
> // Input values (keys). These must be provided to Builder in Unicode
> sorted order!
> String inputValues[] = {"cat", "dog", "dogs"};
> long outputValues[] = {5, 7, 12};
>
> PositiveIntOutputs outputs = PositiveIntOutputs.getSingleton();
> Builder<Long> builder = new Builder<Long>(INPUT_TYPE.BYTE1, outputs);
> BytesRef scratchBytes = new BytesRef();
> IntsRefBuilder scratchInts = new IntsRefBuilder();
> for (int i = 0; i < inputValues.length; i++) {
> scratchBytes.copyChars(inputValues[i]);
> builder.add(Util.toIntsRef(scratchBytes, scratchInts),
> outputValues[i]);
> }
> FST<Long> fst = builder.finish();
> {code}
> Compilation of above code with Solr 8.3 libraries complains that no method
> copyChars found. copyChars method in BytesRef class is deprecated from long
> time. We should use BytesRefBuilder class instead. Here is the correct code:
> {code:java}
> String inputValues[] = {"cat", "dog", "dogs"};
> long outputValues[] = {5, 7, 12};
> PositiveIntOutputs outputs = PositiveIntOutputs.getSingleton();
> Builder<Long> builder = new Builder<Long>(FST.INPUT_TYPE.BYTE1, outputs);
> BytesRefBuilder scratchBytes = new BytesRefBuilder();
> IntsRefBuilder scratchInts = new IntsRefBuilder();
> for (int i = 0; i < inputValues.length; i++) {
> scratchBytes.copyChars(inputValues[i]);
> builder.add(Util.toIntsRef(scratchBytes.get(), scratchInts),
> outputValues[i]);
> }
> FST<Long> fst = builder.finish();
> {code}
>
