SYNOPSIS
#include <antlr3commontoken.h>
Data Fields
The definition of an ANTLR3 common token structure, which all implementations of a token stream should provide, installing any further structures in the custom pointer element of this structure.
Remarks:
The virtual channel that this token exists in.
Referenced by antlr3SetTokenAPI(), emit(), getChannel(), and setChannel().
The character position in the line that this token was derived from.
Referenced by emit(), getCharPositionInLine(), and setCharPositionInLine().
Pointer that is used when the token just has a pointer to a char *, such as when a rewrite of an imaginary token supplies a string in the grammar. No sense in constructing a pANTLR3_STRING just for that, as mostly the text will not be accessed - if it is, then we will build a pANTLR3_STRING for it a that point.
Referenced by antlr3CommonTreeNodeStreamNew(), createToken(), createTokenFromToken(), getText(), and setText8().
Pointer to a custom element that the ANTLR3 programmer may define and install.
Referenced by antlr3SetTokenAPI(), emit(), factoryClose(), and getMissingSymbol().
Indicates that a token was produced from the token factory and therefore the the freeToken() method should not do anything itself because token factory is responsible for deleting it.
Referenced by antlr3LexerNew(), antlr3TokenFactoryNew(), newPoolToken(), newToken(), and nextTokenStr().
Pointer to a function that knows how to free the custom structure when the token is destroyed.
Referenced by antlr3SetTokenAPI(), and factoryClose().
Pointer to a function that gets the channel that this token was placed in (parsers can 'tune' to these channels.

Pointer to a function that gets the offset in the line where this token exists.

Pointer to a function that gets the start index in the input stream for this token.
Referenced by antlr3SetTokenAPI(), getText(), and toString().
Pointer to a function that gets the stop index in the input stream for this token.

Pointer to a function that returns the token type of this token.

What the index of this token is, 0, 1, . ., n-2, n-1 tokens

Pointer to the input stream that this token originated in.

The line number in the input stream where this token was derived from.
Referenced by antlr3SetTokenAPI(), emit(), getLine(), and setLine().
The offset into the input stream that the line in which this token resides starts.

Pointer to a function that sets the offset in the line where this token exists.

Pointer to a function that sets the stop index in the input stream for this token.
Referenced by antlr3SetTokenAPI(), nextTokenStr(), and tokLT().
Pointer to a function that 'might' be able to set the text associated with a token. Imaginary tokens such as an ANTLR3_CLASSIC_TOKEN may actually do this, however many tokens such as ANTLR3_COMMON_TOKEN do not actaully have strings associated with them but just point into the current input stream. These tokens will implement this function with a function that errors out (probably drastically.

A string factory that we can use if we ever need the text of a token and need to manufacture a pANTLR3_STRING.

Some token types actually do carry around their associated text, hence (*getText)() will return this pointer if it is not NULL.
Referenced by createTokenFromToken(), emit(), getText(), setText(), and setText8().
Indicates whether this token is carrying:. State | Meaning ------+-------------------------------------- 0 | Nothing (neither rewrite text, nor setText) 1 | char * to user supplied rewrite text 2 | pANTLR3_STRING because of setText or similar action

The actual type of this token.
Referenced by antlr3SetTokenAPI(), displayRecognitionError(), emit(), getText(), getType(), nextToken(), setType(), and toString().
Because it is a bit more of a hassle to override an ANTLR3_COMMON_TOKEN as the standard structure for a token, a number of user programmable elements are allowed in a token. This is one of them.
