Detailed Description

DtStringKeyConverter is used to convert string-based keys, used in files for things like model sets and observer settings.

The string-based keys make it easier to ensure uniqueness when we may have random plugins creating new keys, but allows us to convert those keys to integers for runtime use. When we need to save, we can convert the integers back to the original string keys. The string key converter provides an integer key on the create key call. DtStringKeyConverters are typically owned and used by managers that read and write settings files.

int makVrv::DtStringKeyConverter::registerStringKey

(

const std::string &

stringKey

)

Register a new string key.

The created integer is returned. Returns -1 if the key already exists.

void makVrv::DtStringKeyConverter::registerStringKey	(	const std::string &	stringKey,
		int	intKey
	)

Register a new string key, specifying the integer key to use.

Only use this if you know your keyspace!

int makVrv::DtStringKeyConverter::lookupIntKey

(

const std::string &

stringKey

)

const

Look up the integer key for this string key.

Returns -1 if the string key doesn't exist

const std::string* makVrv::DtStringKeyConverter::findStringKey

(

int

intKey

)

const

Look up the string key for this integr key.

Returns "" if the integer key doesn't exist
