Robert Muir commented on LUCENE-5999:
-------------------------------------
Instead of:
{code}
final AbstractStandardTokenizer src;
if (getVersion().onOrAfter(Version.LUCENE_4_7_0)) {
src = new StandardTokenizer();
} else {
src = new StandardTokenizer40();
}
src.setMaxTokenLength(maxTokenLength);
{code}
you can do:
{code}
final Tokenizer src;
if (getVersion().onOrAfter(Version.LUCENE_4_7_0)) {
StandardTokenizer t = new StandardTokenizer();
t.setMaxTokenLength(maxTokenLength);
src = t;
} else {
StandardTokenizer40 t = new StandardTokenizer();
t.setMaxTokenLength(maxTokenLength);
src = t;
}
{code}
> Add backcompat support for StandardTokenizer before 4.7
