Alex D Herbert resolved RNG-115. -------------------------------- Fix Version/s: 1.3 Resolution: Implemented In master. > JDKRandom to allow restore state when saved from a different instance > --------------------------------------------------------------------- > > Key: RNG-115 > URL: https://issues.apache.org/jira/browse/RNG-115 > Project: Commons RNG > Issue Type: Bug > Components: core > Affects Versions: 1.2 > Reporter: Alex D Herbert > Assignee: Alex D Herbert > Priority: Minor > Fix For: 1.3 > > Time Spent: 0.5h > Remaining Estimate: 0h > > Currently the size of the serialized state of the java.util.Random used by > JDKRandom is saved to the instance when the state is saved. Thus the state > cannot be used to restore a different instance of the same class. This breaks > the contract of the RestorableUniformRandomProvider as the state should be > applicable to a different instance of the same class. > Fix this test to work: > {code:java} > @Test > public void testRestoreToNewInstance() { > final long seed = 8796746234L; > final JDKRandom rng1 = new JDKRandom(seed); > final JDKRandom rng2 = new JDKRandom(seed + 1); > final RandomProviderState state = rng1.saveState(); > rng2.restoreState(state); > final int numRepeats = 1000; > for (int r = 0; r < numRepeats; r++) { > Assert.assertEquals(r + " nextInt", rng1.nextInt(), rng2.nextInt()); > } > } > {code} -- This message was sent by Atlassian Jira (v8.3.2#803003)
