Artifact 13775b9538812e37714256e5ed447a885d5e1959dc0d837fa5fba94d7abc389f:

• File src/OFSeekableStream.m — part of check-in [37db8f0fb3] at 2010-04-17 22:27:17 on branch trunk — New ivar naming convention.

  ivars are now named like this: thisIsAnIVar. If an accessor exists for
  the ivar, the ivar is named like the accessor. This is required for
  @property to work. (user: js, size: 1367) [annotate] [blame] [check-ins using]
