Example 11 with FilterDirectory

use of org.apache.lucene.store.FilterDirectory in project lucene-solr by apache.

the class BaseCompoundFormatTestCase method testPassIOContext.

// LUCENE-5724: things like NRTCachingDir rely upon IOContext being properly passed down
public void testPassIOContext() throws IOException {
    final String testfile = "_123.test";
    final IOContext myContext = new IOContext();
    Directory dir = new FilterDirectory(newDirectory()) {

        @Override
        public IndexOutput createOutput(String name, IOContext context) throws IOException {
            assertSame(myContext, context);
            return super.createOutput(name, context);
