示例1: testManyContexts

// A test useful for assessing the performance
// of the Context class.
void GafferTest::testManyContexts()
{
	// our typical context doesn't have a huge number of keys - we'll
	// use a working set of 20 for this test.

	ContextPtr base = new Context();
	const int numKeys = 20;
	vector<InternedString> keys;
	for( int i = 0; i < numKeys; ++i )
	{
		InternedString key = string( "testKey" ) + lexical_cast<string>( i );
		keys.push_back( key );
		base->set( key, i );
	}

	// then typically we create new temporary contexts based on that one,
	// change a value or two, and then continue.

	Timer t;
	for( int i = 0; i < 100000; ++i )
	{
		ContextPtr tmp = new Context( *base, Context::Borrowed );
		tmp->set( keys[i%numKeys], i );
		GAFFERTEST_ASSERT( tmp->get<int>( keys[i%numKeys] ) == i );
	}

	// uncomment to get timing information
	//std::cerr << t.stop() << std::endl;
