Detailed DescriptionBase string class tracks the allocations and provides simple string tracking functions. Mostly you can work directly on the string for things that don't reallocate it, like strchr() etc. Perhaps someone will want to provide implementations for UTF8 and so on.

Referenced by antlr38BitReuse(), serializeNode(), and serializeToken().

pANTLR3_UINT8(* ANTLR3_STRING_struct::set8) (struct ANTLR3_STRING_struct *string, const char *chars)Pointer to function that sets the string value to a specific 8 bit string in the default encoding for this string.

struct ANTLR3_STRING_struct*(* ANTLR3_STRING_struct::to8) (struct ANTLR3_STRING_struct *string)Pointer to a function that yields an 8 bit string regardless of the encoding of the supplied string. This is useful when you want to use the text of a token in some way that requires an 8 bit value, such as the key for a hashtable. The function is required to produce a usable string even if the text given as input has characters that do not fit in 8 bit space, it will replace them with some arbitrary character such as '?' Referenced by displayRecognitionError().

ANTLR3_INT32(* ANTLR3_STRING_struct::toInt32) (struct ANTLR3_STRING_struct *string)Pointer to a function that returns the integer representation of any numeric characters at the beginning of the string. Referenced by stringInit8(), and stringInitUTF16().

struct ANTLR3_STRING_struct*(* ANTLR3_STRING_struct::toUTF8) (struct ANTLR3_STRING_struct *string)Pointer to a function that yields a UT8 encoded string of the current string, regardless of the current encoding of the string. Because there is currently no UTF8 handling in the string class, it creates therefore, a string that is useful only for read only applications as it will not contain methods that deal with UTF8 at the moment. Referenced by consumeNode(), createNode(), errorNode(), LTT(), serializeNode(), serializeToken(), stringInit8(), and stringInitUTF16().
