示例1: testFlattenWithDepth
public function testFlattenWithDepth()
{
// No depth flattens recursively
$c = new Collection([['#foo', ['#bar', ['#baz']]], '#zap']);
$this->assertEquals(['#foo', '#bar', '#baz', '#zap'], $c->flatten()->all());
// Specifying a depth only flattens to that depth
$c = new Collection([['#foo', ['#bar', ['#baz']]], '#zap']);
$this->assertEquals(['#foo', ['#bar', ['#baz']], '#zap'], $c->flatten(1)->all());
$c = new Collection([['#foo', ['#bar', ['#baz']]], '#zap']);
$this->assertEquals(['#foo', '#bar', ['#baz'], '#zap'], $c->flatten(2)->all());
}示例2: getMiddleware
/**
* Get the middleware for the controller instance.
*
* @param \Illuminate\Routing\Controller $instance
* @param string $method
* @return array
*/
protected function getMiddleware($instance, $method)
{
$results = new Collection();
foreach ($instance->getMiddleware() as $name => $options) {
if (!$this->methodExcludedByOptions($method, $options)) {
$results[] = $this->router->resolveMiddlewareClassName($name);
}
}
return $results->flatten()->all();
}示例3: testFlattenIgnoresKeys
public function testFlattenIgnoresKeys()
{
// No depth ignores keys
$c = new Collection(['#foo', ['key' => '#bar'], ['key' => '#baz'], 'key' => '#zap']);
$this->assertEquals(['#foo', '#bar', '#baz', '#zap'], $c->flatten()->all());
// Depth of 1 ignores keys
$c = new Collection(['#foo', ['key' => '#bar'], ['key' => '#baz'], 'key' => '#zap']);
$this->assertEquals(['#foo', '#bar', '#baz', '#zap'], $c->flatten(1)->all());
