Artifact e44a0576ae9803c31a2831dd865c840466d75199f8c6601e3f7d0bad2f664ecf:

• File src/OFArray_adjacentSubarray.m — part of check-in [68d32a92c1] at 2014-06-16 15:06:26 on branch trunk — Make return type of -[OFArray objects] const

  After all, this might (and does for OFArray_adjacent!) return an
  internal representation that must not be changed, so changes should be
  prevented at compile-time. (user: js, size: 1622) [annotate] [blame] [check-ins using]
