Make BooleanWeight and DisjunctionMaxWeight protected
-----------------------------------------------------
Key: LUCENE-1784
URL: https://issues.apache.org/jira/browse/LUCENE-1784
Project: Lucene - Java
Issue Type: Improvement
Affects Versions: 2.4
Reporter: Tim Smith
Priority: Minor
Currently, BooleanWeight is private, yet it has 2 protected members
(similarity, weights) which are unaccessible from custom code
i have some use cases where it would be very useful to crawl a BooleanWeight to
get at the sub Weight objects
however, since BooleanWeight is private, i have no way of doing this
If BooleanWeight is protected, then i can subclass BooleanQuery to hook in and
wrap BooleanWeight with a subclass to facilitate this walking of the Weight
objects
Would also want DisjunctionMaxWeight to be protected, along with its "weights"
member
Would be even better if these Weights were made public with accessors to their
sub "weights" objects (then no subclassing would be necessary on my part)
this should be really trivial and would be great if it can get into 2.9
more generally, it would be nice if all Weight classes were public with nice
accessors to relevant "sub weights"/etc so custom code can get its hooks in
where and when desired
