Removing item from vector, while in C++11 range 'for' loop?
...y using:
for (MyVector::iterator b = v.begin(); b != v.end();) {
if (foo) {
b = v.erase( b ); // reseat iterator to a valid value post-erase
else {
++b;
}
}
Note, that you need the b != v.end() test as-is. If you try to optimize it as follows:
for (MyVector::iterator b...

Testing two JSON objects for equality ignoring child order in Java
...could try using json-lib's JSONAssert class:
JSONAssert.assertEquals(
"{foo: 'bar', baz: 'qux'}",
JSONObject.fromObject("{foo: 'bar', baz: 'xyzzy'}")
);
Gives:
junit.framework.ComparisonFailure: objects differed at key [baz]; expected:<[qux]> but was:<[xyzzy]>
...
The key must be an application-specific resource id

You can use any resource - even just take a random R.id.FOO where FOO is some id in your project.

fibs: [1,1,2,3,5,8,13]
just read it with:
>>> json.loads(config.get("Foo","fibs"))
[1, 1, 2, 3, 5, 8, 13]
You can even break lines if your list is long (thanks @peter-smit):
