NAMEANTLR3_TOKEN_FACTORY_struct − ANTLR3 Token factory interface to create lots of tokens efficiently rather than creating and freeing lots of little bits of memory​.

---

SYNOPSIS
#include <antlr3commontoken​.h>

---

Data Fieldsvoid(* close )(struct ANTLR3_TOKEN_FACTORY_struct *factory)
Pointer to a function the destroys the factory​. pANTLR3_INPUT_STREAM input
Pointer to an input stream that is using this token factory (may be NULL) which will be assigned to the tokens automatically​. ANTLR3_INT32 maxPool
Maximum pool count we have available​. pANTLR3_COMMON_TOKEN(* newToken )(struct ANTLR3_TOKEN_FACTORY_struct *factory)
Pointer to a function that returns a new token​. ANTLR3_UINT32 nextToken
The next token to throw out from the pool, will cause a new pool allocation if this exceeds the available tokenCount​. pANTLR3_COMMON_TOKEN * pools
Pointers to the array of tokens that this factory has produced so far​. void(* reset )(struct ANTLR3_TOKEN_FACTORY_struct *factory)
Pointer to a function that resets the factory so you can reuse the pools it has laready allocated​. void(* setInputStream )(struct ANTLR3_TOKEN_FACTORY_struct *factory, pANTLR3_INPUT_STREAM input)
Pointer to a function that changes teh curent inptu stream so that new tokens are created with reference to their originating text​. ANTLR3_INT32 thisPool
Current pool tokens we are allocating from​. ANTLR3_COMMON_TOKEN unTruc
Trick to initialize tokens and their API quickly, we set up this token when the factory is created, then just copy the memory it uses into the new token​.
