-------------------------------------
Summary: Compile error with FST package example code
Key: LUCENE-6112
URL: https://issues.apache.org/jira/browse/LUCENE-6112
Project: Lucene - Core
Issue Type: Task
Components: core/FSTs
Affects Versions: 4.10.2
Reporter: Tomoko Uchida
Priority: Minor
I run the FST construction example guided package.html with lucene 4.10, and
found a compile error.
http://lucene.apache.org/core/4_10_2/core/index.html?org/apache/lucene/util/fst/package-summary.html
javac claimed as below.
"FSTTest" is my test class, just copied from javadoc's example.
{code}
$ javac -cp /opt/lucene-4.10.2/core/lucene-core-4.10.2.jar FSTTest.java
FSTTest.java:28: error: method toIntsRef in class Util cannot be applied to
given types;
builder.add(Util.toIntsRef(scratchBytes, scratchInts), outputValues[i]);
^
required: BytesRef,IntsRefBuilder
found: BytesRef,IntsRef
reason: actual argument IntsRef cannot be converted to IntsRefBuilder by
method invocation conversion
Note: FSTTest.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
1 error
{code}
I modified scratchInts variable type from IntsRef to IntsRefBuilder, it worked
fine. (I checked o.a.l.u.fst.TestFSTs.java TestCase and my modification seems
to be correct.)
Util.toIntsRef() method takes IntsRefBuilder as 2nd argument instead of IntsRef
since 4.10, so Javadocs also should be fixed.
