Provides string representation for enums.
The class basically implements efficient integer-to-string and string-to-integer mapping. The primary usage is to support displaying symbolic names for integer enum values.

Constructor.

Destructor.
Assignment operator. The name member is not copied; see cOwnedObject's operator=() for more details.

inlineoverridevirtual |
|
overridevirtual |
Returns a textual representation of this enum.
Reimplemented from cObject.
void insert | ( | intval_t | value, |
const char * | name | ||
) |
Add an item to the enum. If that numeric code exist, overwrite it.
const char* getStringFor | ( | intval_t | value | ) |
Look up value and return string representation. Return nullptr if not found.
Referenced by cEnum::getNameForValue().
Look up string and return numeric code. If not found, return second argument (or -1).
intval_t resolve | ( | const char * | name | ) |
Look up string and return numeric code. Throws an error if not found.
Referenced by cEnum::resolveName().
|
inlinestatic |
Resolve a string and return the corresponding value in the enum type given as template argument. The enum must have been registered previously with one of the Register_Enum() macros.
Example:
References omnetpp::opp_typename(), and cEnum::resolve().
|
inlinestatic |
Resolve an enum value of type E and return the corresponding string representation. The enum must have been registered previously with one of the Register_Enum() macros.
Example:
References cEnum::getStringFor(), and omnetpp::opp_typename().
|
inline |
Returns a map with the enum members (names as key, and numeric value map value).
|
static |
Returns the cEnum for the given enum name, or nullptr if not found. The enum must have been registered previously with one of the Register_Enum() macros.
|
static |
Like find(), but throws an error if the object was not found.
