keyToString()

const std::string * SG::StringPoolImpl::keyToString	(	StringPool::sgkey_t	key,
		StringPool::sgaux_t &	aux
	)		const

Find the string corresponding to a given key.

Parameters

key	The key to look up.
aux[out]	Auxiliary data associated with the key.

Returns

Pointer to the string found, or null. We can find keys as long as the corresponding string was given to either stringToKey() or registerKey().

Definition at line 99 of file StringPool.cxx.

{
  StringPoolImpl::keymap_t::const_iterator i = m_keymap.find (key);
  if (i != m_keymap.end()) {
    aux = i->second.first;
    return &i->second.second;
  }
  return 0;
}

merge()

bool SG::StringPoolImpl::merge

(

const StringPoolImpl &

other

)

Merge other pool into this one.

Merge another pool into this one.

Parameters

other

The other pool to merge into this one.

In case of collisions, the colliding entries are skipped, and false is returned. If no collisions, then true is returned.

Definition at line 155 of file StringPool.cxx.

{
  bool allgood = true;
  for (const keymap_t::value_type& p : other.m_keymap) {
    if (!registerKey (p.first, p.second.second, p.second.first)) {
      allgood = false;
    }
  }
  return allgood;
}

registerKey()

bool SG::StringPoolImpl::registerKey	(	StringPool::sgkey_t	key,
		const std::string &	str,
		StringPool::sgaux_t	aux
	)

Remember an additional mapping from key to string.

Parameters

key	The key to enter.
str	The string to enter.
aux	Auxiliary data to include along with the string.

Returns

True if successful; false if the key already corresponds to a different string.

Definition at line 73 of file StringPool.cxx.

{
  StringPoolImpl::keymap_t::iterator i = m_keymap.find (key);
  if (i == m_keymap.end()) {
    pair_t& p = m_keymap[key];
    p.first = aux;
    p.second = str;
  }
  else if (i->second.first != aux || i->second.second != str) {
    return false;
  }
  return true;
}

size()

size_t SG::StringPoolImpl::size

(

)

const

Number of registered mappings.

Definition at line 114 of file StringPool.cxx.

{
  return m_keymap.size();
