Constructor & Destructor Documentation

◆ ObjectFinder() [1/3]

Botan::PKCS11::ObjectFinder::ObjectFinder	(	Session &	session,
		const std::vector< Attribute > &	search_template
	)

Initializes a search for token and session objects that match a template (calls C_FindObjectsInit)

Parameters

session	the session to use for the search
search_template	the search_template as a vector of `Attribute`

Definition at line 90 of file p11_object.cpp.

   : m_session(session), m_search_terminated(false)
   {
   module()->C_FindObjectsInit(m_session.get().handle(),
                               const_cast< Attribute* >(search_template.data()),
                               static_cast<Ulong>(search_template.size()));

Member Function Documentation

◆ find()

std::vector< ObjectHandle > Botan::PKCS11::ObjectFinder::find ( std::uint32_t max_count = 100 ) const

Starts or continues a search for token and session objects that match a template, obtaining additional object handles (calls C_FindObjects)

Parameters

max_count maximum amount of object handles to retrieve. Default = 100

Returns: the result of the search as a vector of ObjectHandle

Definition at line 113 of file p11_object.cpp.

   {
   std::vector<ObjectHandle> result(max_count);
   Ulong objectCount = 0;
   module()->C_FindObjects(m_session.get().handle(), result.data(), max_count, &objectCount);
   if(objectCount < max_count)
      {
      result.resize(objectCount);
      }
   return result;
   }

◆ finish()

void Botan::PKCS11::ObjectFinder::finish ( )

Finishes the search operation manually to allow a new ObjectFinder to exist.

   module()->C_FindObjectsFinal(m_session.get().handle());
   m_search_terminated = true;
