ConcurrentVectorMemoryPool#

Fully qualified name: usd_optimize::ConcurrentVectorMemoryPool

Classes Summary#

Vec: Scoped wrapper around a memory pool allocated vector. This means the vector is deallocated when the wrapper goes out of scope.

template<typename T> class ConcurrentVectorMemoryPool#

Manages a pool of vectors of type T that can be accessed concurrently. If there are no free vectors available, a new one is allocated. Note: this does not garbage collect, the destructor or clear must be called to release memory.

Public Functions

inline ConcurrentVectorMemoryPool(bool active)#

inline ~ConcurrentVectorMemoryPool()#

ConcurrentVectorMemoryPool(const ConcurrentVectorMemoryPool&) = delete#

ConcurrentVectorMemoryPool &operator=( const ConcurrentVectorMemoryPool&, ) = delete#

inline void setActive(bool active)#: Sets whether this memory pool is active or not. If it is not active, then all vectors are allocated directly and not from the pool note: this function calls clear so it is not thread safe and should only be called when no other threads are using the pool.

inline Vec allocate(size_t size = 0)#

Either allocates a new vector or returns an existing one from the pool.

Parameters:: size – The minimum size that the vector should have of reserved memory.

inline void clear()#: Frees all vectors in the pool. Warning: Calling clear is not thread safe and should only be called when no other threads are using the pool.

Protected Functions

inline void deallocate(std::vector<T> *vec)#: Returns the vector to the pool. The vector must have been allocated from this pool.

class Vec#

Scoped wrapper around a memory pool allocated vector. This means the vector is deallocated when the wrapper goes out of scope.

Public Functions

inline ~Vec()#

Vec(const Vec&) = delete#

Vec &operator=(const Vec&) = delete#

inline std::vector<T> &get()#

Protected Functions

inline Vec( ConcurrentVectorMemoryPool &memPool, std::vector<T> *vec, )#
