From e48d8b88869563f85f2c83108257615f1cc73c76 Mon Sep 17 00:00:00 2001 From: Michael Koch Date: Tue, 13 May 2003 09:13:31 +0000 Subject: 2003-05-13 Michael Koch * java/io/FileDescriptor.java (SYNC): New constant. (DSYNC): Likewise. (getLength): Renamed from lenght() to match classpath's FileDescriptor.java. * java/io/RandomAccessFile.java (RandomAccessFile): Removed unneeded mode check, implemented mode "rws" and "rwd", merged documentation from classpath. (setLength): Reformatted. (length): Use new getLength() of FileDescriptor. * java/io/natFileDescriptorEcos.cc (getLength): Renamed from length(). * java/io/natFileDescriptorPosix.cc (open): Implemented support for SYNC and DSYNC. (seek): Use getLength() instead of length(). (getLength): Renamed from length(). * java/io/natFileDescriptorWin32.cc (getLength): Renamed from length(). (seek): Use getLength() instead of length(). (available): Likewise. * gnu/java/nio/natFileChannelImpl.cc (size): Use getLength() instead of length().
