• File src/OFFloatMatrix.m — part of check-in [927dbf6e7d] at 2011-08-07 16:57:49 on branch trunk — Add -[makeImmutable] to all mutable classes and use it. (user: js, size: 9955) [annotate] [blame] [check-ins using]

To Artifact [0e7f420221]:

• File src/OFFloatMatrix.m — part of check-in [f3db074478] at 2011-09-17 19:18:09 on branch trunk — Make hashes independant of endianess in OF{Float,Double}{Vector,Matrix}.

  Also removes unnecessary OF_HASH_ADD_INT* macros (except
  OF_HASH_ADD_INT32 which was often used to hash hashes and is now called
  OF_HASH_ADD_HASH). (user: js, size: 10040) [annotate] [blame] [check-ins using]
