Member Function Documentation

keyToString() [1/2]

virtual const std::string * IStringPool::keyToString ( sgkey_t key ) const

pure virtual

Find the string corresponding to a given key.

Parameters

key	The key to look up.

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().

keyToString() [2/2]

virtual const std::string * IStringPool::keyToString ( sgkey_t key, CLID & clid ) const

pure virtual

Find the string and CLID corresponding to a given key.

Parameters

key	The key to look up.
clid[out]	The found CLID.

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().

registerKey()

virtual void IStringPool::registerKey ( sgkey_t key, const std::string & str, CLID clid )

pure virtual

Remember an additional mapping from key to string/CLID.

Parameters

key	The key to enter.
str	The string to enter.
clid	The CLID associated with the string.

Returns

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

This registers an additional mapping from a key to a string; it can be found later through lookup() on the string. Logs an error if key already corresponds to a different string.

stringToKey()

virtual sgkey_t IStringPool::stringToKey ( const std::string & str, CLID clid )

pure virtual

Find the key for a string/CLID pair.

Parameters

str	The string to look up.
clid	The CLID associated with the string.

Returns

A key identifying the string. A given string will always return the same key. Will abort in case of a hash collision!
