Detailed Description

template<class T>
class ucommon::paged_reuse< T >

A reusable private pool of reusable types.

A pool of typed objects is created which can be allocated from a memory pager. Deallocated typed objects are also returned to this pool so they can be reallocated later.

Constructor & Destructor Documentation

template<class T >
ucommon::paged_reuse< T >::paged_reuse ( mempager pager,
unsigned  count 
)
inline

Create a managed reusable typed object pool.

This manages a heap of typed objects that can either be reused from released objects or allocate from an existing memory pager pool.

Parameters
pagerpool to allocate from.
countof objects of specified type to allocate.

Member Function Documentation

template<class T >
T* ucommon::paged_reuse< T >::create ( void  )
inline

Get a typed object from the pager heap.

This function blocks when the heap is empty until an object is returned to the heap. The objects default constructor is used.

Returns
typed object pointer from heap.

Definition at line 625 of file vector.h.

template<class T >
T* ucommon::paged_reuse< T >::create ( timeout_t  timeout)
inline

Create a typed object from the heap.

This function blocks until the the heap has an object to return or the timer has expired. The objects default constructor is used.

Parameters
timeoutto wait for heap in milliseconds.
Returns
typed object pointer from heap or NULL if timeout.

Definition at line 644 of file vector.h.

template<class T >
T* ucommon::paged_reuse< T >::get ( void  )
inline

Get a typed object from the pager heap.

This function blocks when the heap is empty until an object is returned to the heap.

Returns
typed object pointer from heap.

Reimplemented from ucommon::PagerReuse.

Definition at line 616 of file vector.h.

template<class T >
T* ucommon::paged_reuse< T >::get ( timeout_t  timeout)
inline

Get a typed object from the heap.

This function blocks until the the heap has an object to return or the timer has expired.

Parameters
timeoutto wait for heap in milliseconds.
Returns
typed object pointer from heap or NULL if timeout.

Reimplemented from ucommon::PagerReuse.

Definition at line 634 of file vector.h.

template<class T >
ucommon::paged_reuse< T >::operator bool ( )
inline

Test if typed objects available from the pager or re-use list.

Returns
true if objects still are available.

Definition at line 601 of file vector.h.

template<class T >
ucommon::paged_reuse< T >::operator T * ( )
inline

Get a typed object from the pager heap by pointer reference.

This function blocks while the heap is empty.

Returns
typed object pointer from heap.

Definition at line 674 of file vector.h.

template<class T >
bool ucommon::paged_reuse< T >::operator! ( )
inline

Test if no objects are available for reuse or the pager.

Returns
true if no objects are available.

Definition at line 608 of file vector.h.

template<class T >
T* ucommon::paged_reuse< T >::operator* ( )
inline

This function blocks while the heap is empty.

Returns
typed object pointer from heap.

Definition at line 666 of file vector.h.

template<class T >
void ucommon::paged_reuse< T >::release ( T *  object)
inline

Release (return) a typed object back to the pager heap for re-use.

Parameters
objectto return.
