public abstract class JarScanner
extends PatternMatcher

JarScannerConfiguration Abstract base class for configurations that want to scan jars in WEB-INF/lib and the classloader hierarchy. Jar name matching based on regexp patterns is provided. Subclasses should implement the processEntry(URL jarUrl, JarEntry entry) method to handle entries in jar files whose names match the supplied pattern.

processEntry

public abstract void processEntry(URI jarUri,
                                  JarEntry entry)

scan

public void scan(Pattern pattern,
                 URI[] uris,
                 boolean isNullInclusive)
          throws Exception

Find jar names from the provided list matching a pattern. If the pattern is null and isNullInclusive is true, then all jar names will match. A pattern is a set of acceptable jar names. Each acceptable jar name is a regex. Each regex can be separated by either a "," or a "|". If you use a "|" this or's together the jar name patterns. This means that ordering of the matches is unimportant to you. If instead, you want to match particular jar names, and you want to match them in order, you should separate the regexs with "," instead. Eg "aaa-.\*\.jar|bbb-.\*\.jar" Will iterate over the jar names and match in any order. Eg "aaa-\*\.jar,bbb-.\*\.jar" Will iterate over the jar names, matching all those starting with "aaa-" first, then "bbb-".

参数：

pattern -

uris -

isNullInclusive - if true, an empty pattern means all names match, if false, none match

抛出：

Exception

scan

public void scan(Pattern pattern,
                 ClassLoader loader,

                 boolean visitParent)
          throws Exception

Find jar names from the classloader matching a pattern. If the pattern is null and isNullInclusive is true, then all jar names in the classloader will match.

Eg "aaa-\*\.jar,bbb-.\*\.jar" Will iterate over the jar names in the classloader, matching all those starting with "aaa-" first, then "bbb-". If visitParent is true, then the pattern is applied to the parent loader hierarchy. If false, it is only applied to the classloader passed in.
