[Framework] Try to improve performance of parseDelimitedString() in manifest
parser
-----------------------------------------------------------------------------------
Key: FELIX-2804
URL: https://issues.apache.org/jira/browse/FELIX-2804
Project: Felix
Issue Type: Improvement
Components: Framework
Affects Versions: framework-3.0.7
Reporter: Richard S. Hall
Priority: Minor
Fix For: framework-3.2.0
Currently, we are using StringBuffer and appending one character at a time
while parsing a delimited string. As we discovered when implementing our custom
manifest parser, such an approach is not really very efficient. It is better to
keep track of beginning/ending indexes and just extracting strings as needed.
We should probably do something similar here. It may not offer great
improvement, but this routine is used to parse pretty long import/export
headers, so you never know.
