From 63a82400596b9331d1babe88624f97209286d0b9 Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Fri, 9 Feb 2007 16:44:02 -0800 Subject: Get rid of the Random context and add the support directly to python. We don't currently use randomness much, so I didn't go too far, but in the future, we may want to actually expose the random number values themselves to python. For now, I'll at least let you seed it. While we're at it, clean up a clearly bad way for generating random doubles. --HG-- extra : convert_revision : df2aa8b58dd0d9c2a7c771668a760b2df8db1e11 --- src/python/swig/random.i | 55 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 src/python/swig/random.i (limited to 'src/python/swig') diff --git a/src/python/swig/random.i b/src/python/swig/random.i new file mode 100644 index 000000000..657a59780 --- /dev/null +++ b/src/python/swig/random.i @@ -0,0 +1,55 @@ +/* + * Copyright (c) 2006 The Regents of The University of Michigan + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are + * met: redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer; + * redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution; + * neither the name of the copyright holders nor the names of its + * contributors may be used to endorse or promote products derived from + * this software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS + * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT + * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR + * A PARTICULAR PURPOSE ARE DISCLAIMED.
