Constructor & Destructor Documentation

◆ KeyV1Owned() [1/2]

mongo::KeyV1Owned::KeyV1Owned ( const BSONObj & obj )

a BSON object to be translated to KeyV1 format.

If the object isn't representable in KeyV1 format (which happens, intentionally, at times) it will stay as bson herein.

mongo::KeyV1Owned::KeyV1Owned ( const KeyV1 & rhs )

makes a copy (memcpy's the whole thing)

void mongo::KeyV1Owned::operator= ( const KeyV1Owned & )

private

void mongo::KeyV1Owned::traditional ( const BSONObj & obj )

private

object cannot be represented in compact format.

so store in traditional bson format with a leading sentinel byte IsBSON to indicate it's in that format.

Given that the KeyV1Owned constructor already grabbed a bufbuilder, we reuse it here so that we don't have to do an extra malloc.
