Detailed Description

This complex constrained in-core value-semantic class holds the information necessary for ManagedPtr to correctly manage its underlying object, namely the addresses of object and factory, and the deleter function, optionally supplied through the constructors or through the set method. This information is stored in a sub-structure to allow the compiler to copy it more efficiently.

See the {Attributes} section in the component-level documentation. Note that the class invariants are identically the constraints on the individual attributes.

This class:

• supports a complete set of value-semantic operations
• is exception-safe
• is alias-safe
• is const thread-safe For terminology see bsldoc_glossary .

Member Typedef Documentation

Deleter

typedef void(* bslma::ManagedPtrDeleter::Deleter) (void *managedObject, void *cookie)

Constructor & Destructor Documentation

ManagedPtrDeleter() [1/3]

bslma::ManagedPtrDeleter::ManagedPtrDeleter ( )

inline

Create a default ManagedPtrDeleter object that does not refer to any object or factory instance.

ManagedPtrDeleter() [2/3]

bslma::ManagedPtrDeleter::ManagedPtrDeleter ( void *  object, void *  factory, Deleter  deleter  )

inline

Create a ManagedPtrDeleter object that refers to the object and factory instances located at the specified object and factory memory locations, and the specified deleter. The behavior is undefined unless deleter is either 0, or points to a function whose behavior is defined if called once with object and factory as arguments.

ManagedPtrDeleter() [3/3]

bslma::ManagedPtrDeleter::ManagedPtrDeleter

(

const ManagedPtrDeleter &

original

)

Create a ManagedPtrDeleter object having the same value as the specified original object. Note that this trivial copy constructor's definition is compiler generated.

~ManagedPtrDeleter()

bslma::ManagedPtrDeleter::~ManagedPtrDeleter ( )

default

Destroy this object. Note that this trivial destructor's definition is compiler generated.

Member Function Documentation

clear()

void bslma::ManagedPtrDeleter::clear ( )

inline

deleteManagedObject()

void bslma::ManagedPtrDeleter::deleteManagedObject ( ) const

inline

Invoke the deleter object. The behavior is undefined unless deleter is not 0 and has not already been called on the managed object associated with this deleter.

deleter()

ManagedPtrDeleter::Deleter bslma::ManagedPtrDeleter::deleter ( ) const

inline

factory()

void * bslma::ManagedPtrDeleter::factory ( ) const

inline

Return a pointer to the factory instance associated with this deleter.

object()

void * bslma::ManagedPtrDeleter::object ( ) const

inline

operator=()

ManagedPtrDeleter & bslma::ManagedPtrDeleter::operator=

(

const ManagedPtrDeleter &

rhs

)

Assign to this object the value of the specified rhs object, and return a reference providing modifiable access to this object. Note that this trivial copy-assignment operator's definition is compiler generated.

set()

void bslma::ManagedPtrDeleter::set ( void *  object, void *  factory, Deleter  deleter  )

inline

Set this ManagedPtrDeleter to refer to the object and factory instances located at the specified object and factory memory locations, and the specified deleter. The behavior is undefined unless deleter is either 0, or points to a function whose behavior is defined if called once with object and factory as arguments.
