Symbol Class Reference

The Symbol class provides a method for uniquely storing strings and quickly comparing them for identity. Symbol's are small enough that they should never be passed by pointer nor by reference. Comparison operators for Symbol's and String's are predefined as well.

Symbol Member Functions

Symbol()
Symbol(const char *cp)
Symbol(const String &orig)
Symbol(Symbol s): Constructors.
int operator==(Symbol s) const
int operator<(Symbol s) const: Return result of relational operator. Testing for equality and inequality is fast, all other comparisons use the String class's operators.
bool empty() const: Returns true if the symbol is empty (i.e., constructed with the default constructor or from an empty string).
const char *chars() const: Return the character string associated with the symbol.

Example


#include <mol/Symbol.h>



Symbol name("name");
