This is used for storing a namespace on disk in a fixed witdh form and should only be used for that, not for passing internally.

If you need to pass internally, please use NamespaceString.

extraName()

std::string mongo::Namespace::extraName ( int  i ) const

NamespaceDetails::Extra was added after fact to allow chaining of data blocks to support more than 10 indexes (more than 10 IndexDetails).

It's a bit hacky because of this late addition with backward file support.

hasDollarSign()

bool mongo::Namespace::hasDollarSign ( ) const

inline

hash()

int mongo::Namespace::hash ( ) const

inline

Value returned is always > 0.

isExtra()

bool mongo::Namespace::isExtra ( ) const

inline

Returns whether the namespace ends with "$extr...".

When true it represents an extra block not a normal NamespaceDetails block.

kill()

void mongo::Namespace::kill ( )

inline

operator std::string()

mongo::Namespace::operator std::string ( ) const

inline

operator!=() [1/2]

bool mongo::Namespace::operator!= ( const char *  r ) const

inline

operator!=() [2/2]

bool mongo::Namespace::operator!= ( const Namespace &  r ) const

inline

operator=()

Namespace& mongo::Namespace::operator= ( StringData  ns )

inline

operator==() [1/2]

bool mongo::Namespace::operator== ( const char *  r ) const

inline

operator==() [2/2]

bool mongo::Namespace::operator== ( const Namespace &  r ) const

inline

size()

size_t mongo::Namespace::size ( ) const
