Minor changes to SimpleHTMLFormatter
------------------------------------
Key: LUCENE-1497
URL: https://issues.apache.org/jira/browse/LUCENE-1497
Project: Lucene - Java
Issue Type: Improvement
Components: contrib/highlighter
Reporter: Shai Erera
Priority: Minor
Fix For: 2.4.1, 2.9
I'd like to make few minor changes to SimpleHTMLFormatter.
1. Define DEFAULT_PRE_TAG and DEFAULT_POST_TAG and use them in the default
constructor. This will not trigger String lookups by the JVM whenever the
highlighter is instantiated.
2. Create the StringBuffer in highlightTerm with the right number of characters
from the beginning. Even though StringBuffer's default constructor allocates 16
chars, which will probably be enough for most highlighted terms (pre + post
tags are 7 chars, which leaves 9 chars for terms), I think it's better to
allocate SB with the right # of chars in advance, to avoid char[] allocations
in the middle.
