ANTLR3_TOKEN_UP (3) - Linux Manuals

NAME

include/antlr3commontoken.h -

Defines the interface for a common token.

SYNOPSIS

#include <antlr3defs.h>

Data Structures

struct ANTLR3_COMMON_TOKEN_struct
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.
struct ANTLR3_TOKEN_FACTORY_struct
ANTLR3 Token factory interface to create lots of tokens efficiently rather than creating and freeing lots of little bits of memory.

Defines

#define ANTLR3_EOR_TOKEN_TYPE 1

#define ANTLR3_FACTORY_POOL_SIZE 1024
How many tokens to allocate at once in the token factory.
#define ANTLR3_MIN_TOKEN_TYPE ANTLR3_TOKEN_UP + 1
First token that can be used by users/generated code.
#define ANTLR3_TEXT_CHARP 1

#define ANTLR3_TEXT_NONE 0

#define ANTLR3_TEXT_STRING 2

#define ANTLR3_TOKEN_DEFAULT_CHANNEL 0
Default channel for a token.
#define ANTLR3_TOKEN_DOWN 2
Imaginary token type to cause a traversal of child nodes in a tree parser.
#define ANTLR3_TOKEN_EOF (ANTLR3_CHARSTREAM_EOF & 0xFFFFFFFF)
End of file token.
#define ANTLR3_TOKEN_INVALID 0
Indicator of an invalid token.
#define ANTLR3_TOKEN_UP 3
Imaginary token type to signal the end of a stream of child nodes.
#define HIDDEN 99
Reserved channel number for a HIDDEN token - a token that is hidden from the parser.

Typedefs

typedef struct ANTLR3_COMMON_TOKEN_struct ANTLR3_COMMON_TOKEN
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.
typedef struct ANTLR3_TOKEN_FACTORY_struct ANTLR3_TOKEN_FACTORY
ANTLR3 Token factory interface to create lots of tokens efficiently rather than creating and freeing lots of little bits of memory.

Detailed Description

Defines the interface for a common token.

All token streams should provide their tokens using an instance of this common token. A custom pointer is provided, wher you may attach a further structure to enhance the common token if you feel the need to do so. The C runtime will assume that a token provides implementations of the interface functions, but all of them may be rplaced by your own implementation if you require it.

Typedef Documentation

typedef struct ANTLR3_COMMON_TOKEN_struct

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:

Token streams are in essence provided by lexers or other programs that serve as lexers.

typedef struct ANTLR3_TOKEN_FACTORY_struct

ANTLR3 Token factory interface to create lots of tokens efficiently rather than creating and freeing lots of little bits of memory.
