示例1: matches
bool TypeMatchExpression::matches(const MatchableDocument* doc, MatchDetails* details) const {
MatchableDocument::IteratorHolder cursor(doc, &_elementPath);
while (cursor->more()) {
ElementIterator::Context e = cursor->next();
// In the case where _elementPath is referring to an array,
// $type should match elements of that array only.
// outerArray() helps to identify elements of the array
// and the containing array itself.
// This matters when we are looking for {$type: Array}.
// Example (_elementPath refers to field 'a' and _type is Array):
// a : [ // outer array. should not match
// 123, // inner array
// [ 456 ], // inner array. should match
// ...
// ]
if (_type == mongo::Array && e.outerArray()) {
continue;
}
if (!matchesSingleElement(e.element())) {
continue;
