Detailed Description

template<class T, typename std::enable_if< std::is_default_constructible< T >::value, bool >::type = true>
class pcpp::internal::DynamicObjectPool< T, type >

A generic object pool implementation.

This class provides a generic object pool that can be used to efficiently manage and reuse objects of any type. Objects can be acquired from the pool using the acquireObject method, and released back to the pool using the releaseObject method. If the pool is empty when acquiring an object, a new object will be created. If the pool is full when releasing an object, the object will be deleted.

Template Parameters

T	The type of objects managed by the pool. Must be default constructable.

Constructor & Destructor Documentation

DynamicObjectPool()

template<class T , typename std::enable_if< std::is_default_constructible< T >::value, bool >::type = true>

pcpp::internal::DynamicObjectPool< T, type >::DynamicObjectPool ( std::size_t  maxPoolSize = DEFAULT_POOL_SIZE, std::size_t  initialSize = 0  )

inlineexplicit

Parameters

[in]	maxPoolSize	The maximum number of objects in the pool
[in]	initialSize	The number of objects to preallocate in the pool

Member Function Documentation

acquireObject()

template<class T , typename std::enable_if< std::is_default_constructible< T >::value, bool >::type = true>

std::unique_ptr<T> pcpp::internal::DynamicObjectPool< T, type >::acquireObject ( )

inline

Acquires a unique pointer to an object from the pool.

This method acquires a unique pointer to an object from the pool. If the pool is empty, a new object will be created.

Returns

A unique pointer to an object from the pool.

acquireObjectRaw()

template<class T , typename std::enable_if< std::is_default_constructible< T >::value, bool >::type = true>

T* pcpp::internal::DynamicObjectPool< T, type >::acquireObjectRaw ( )

inline

Acquires a raw pointer to an object from the pool.

This method acquires a raw pointer to an object from the pool. If the pool is empty, a new object will be created.

Returns

A raw pointer to an object from the pool.

preallocate()

template<class T , typename std::enable_if< std::is_default_constructible< T >::value, bool >::type = true>

void pcpp::internal::DynamicObjectPool< T, type >::preallocate ( std::size_t  count )

inline

Pre-allocates up to a minimum number of objects in the pool.

Parameters

count

The number of objects to pre-allocate.

releaseObject()

template<class T , typename std::enable_if< std::is_default_constructible< T >::value, bool >::type = true>

void pcpp::internal::DynamicObjectPool< T, type >::releaseObject ( std::unique_ptr< T >  obj )

inline

Releases a unique pointer to an object back to the pool.

This method releases a unique pointer to an object back to the pool. If the pool is full, the object will be deleted.

Parameters

[in]

obj

The unique pointer to the object to release.

releaseObjectRaw()

template<class T , typename std::enable_if< std::is_default_constructible< T >::value, bool >::type = true>

void pcpp::internal::DynamicObjectPool< T, type >::releaseObjectRaw ( T *  obj )

inline

Releases a raw pointer to an object back to the pool.

This method releases a raw pointer to an object back to the pool. If the pool is full, the object will be deleted.

Parameters

[in]

obj

The raw pointer to the object to release.
