---

Member Function Documentation

---

void SbFifo::assign (void * ptr, uint32_t type) [inline]Puts pointer ptr of type type into the fifo​. The type argument is just meant as a user data tag, and a 0 value can be given as the type argument if type data is uninteresting​.

---

void SbFifo::retrieve (void *& ptr, uint32_t & type) [inline]Reads a pointer from the queue​. Blocks until a pointer is available for reading​.

---

SbBool SbFifo::tryRetrieve (void *& ptr, uint32_t & type) [inline]Tries to read a pointer from the queue​. If no data can be read, FALSE is returned, and TRUE otherwise​. The function does not block​.

---

unsigned int SbFifo::size (void) const [inline]Returns number of pointers currently in the queue​.

---

void SbFifo::lock (void) const [inline]Blocks until the queue can be locked​.

---

void SbFifo::unlock (void) const [inline]Unlocks the queue​.

---

SbBool SbFifo::peek (void *& item, uint32_t & type) const [inline]Peeks at the head item of the queue without removing it​. In the case where the fifo is empty, FALSE is returned​. The queue must be locked with SbFifo::lock() before using this function, then unlocked​.

---

SbBool SbFifo::contains (void * item) const [inline]Returns TRUE or FALSE depending on whether the item is in the queue​. The queue must be locked with SbFifo::lock() before using this function, then unlocked​.

---

SbBool SbFifo::reclaim (void * item) [inline]This function removes the given item from the queue​. Returns TRUE or FALSE depending on whether the item was in the queue in the first place​. The queue must be locked with SbFifo::lock() before using this function, then unlocked​.
