Thomas Mueller commented on OAK-445:
------------------------------------
SVN isn't working currently it seems but the code is basically
{code}
// must be a power of 2
static final int STRING_CACHE_SIZE = 1024;
static final String[] STRING_CACHE = new String[STRING_CACHE_SIZE];
static String getCachedString(String s) {
int index = s.hashCode() & (STRING_CACHE_SIZE - 1);
String cached = STRING_CACHE[index];
if (s.equals(cached)) {
return cached;
}
STRING_CACHE[index] = s;
return s;
}
{code}
> Allow JSON strings to be reclaimed after they've been parsed

> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core
> Reporter: Jukka Zitting
> Assignee: Jukka Zitting
> Priority: Minor
>
> Currently the JsopTokenizer uses String.substring() when returning various
> tokens. This can be a bit troublesome as the returned String instances often
> keep a reference to the full underlying JSON string, which prevents that one
> from being reclaimed.
> It would also be nice if the tokenizer automatically detected common tokens
> like "jcr:primaryType" or "nt:unstructured" and use flyweight instances to
> avoid too many duplicate copies of such strings.
