Example 1 with UTF8StreamWriter

use of org.elasticsearch.common.io.UTF8StreamWriter in project elasticsearch by elastic.

the class MustacheScriptEngineService method utf8StreamWriter.

/** If exists, reset and return, otherwise create, reset and return a writer.*/
private static UTF8StreamWriter utf8StreamWriter() {
    SoftReference<UTF8StreamWriter> ref = utf8StreamWriter.get();
    UTF8StreamWriter writer = (ref == null) ? null : ref.get();
    if (writer == null) {
        writer = new UTF8StreamWriter(1024 * 4);
        utf8StreamWriter.set(new SoftReference<>(writer));
    }
    writer.reset();
    return writer;
}

Example 2 with UTF8StreamWriter

use of org.elasticsearch.common.io.UTF8StreamWriter in project elasticsearch by elastic.

the class RestTable method buildTextPlainResponse.
