cvs commit: jakarta-tomcat-connectors/jk/java/org/apache/jk/apr AprInputStream.java AprOutputStream.java AprSocketServer.java
costin 02/01/11 20:00:15
Added: jk/java/org/apache/jk/apr AprInputStream.java
AprOutputStream.java AprSocketServer.java
Log:
Abstractions for the apr is, os, socket. Initial version based on JFC's
unix socket ( which will eventually be part of the standard apr ).
Those are very early, and jk is using the AprImpl directly. In time
we should make them implement completely the java interfaces ( for
example use Socket, etc ).
