Detailed Description

template<class TYPE>
class ACE_TSS< TYPE >

Allows objects that are "physically" in thread specific storage (i.e., private to a thread) to be accessed as though they were "logically" global to a program.

This class is a wrapper around the OS thread library thread-specific functions. It uses the <C++ operator->> to shield applications from the details of accessing thread-specific storage.

NOTE: For maximal portability, <TYPE> cannot be a built-in type, but instead should be a user-defined class (some compilers will allow a built-in type, others won't). See template class ACE_TSS_Type_Adapter, below, for adapting built-in types to work with ACE_TSS.


Constructor & Destructor Documentation

template<class TYPE>
ACE_INLINE ACE_TSS< TYPE >::ACE_TSS TYPE *    ts_obj = 0
 

If caller has passed us a non-NULL ts_obj *, then we'll just use this to initialize the thread-specific value (but only for the calling thread). Thus, subsequent calls to <operator->> in this thread will return this value. This is useful since it enables us to assign objects to thread-specific data that have arbitrarily complex constructors.

template<class TYPE>
ACE_TSS< TYPE >::~ACE_TSS void    [virtual]
 

Deregister with thread-key administration.

template<class TYPE>
ACE_TSS< TYPE >::ACE_TSS const ACE_TSS< TYPE > &    [protected]
 


Member Function Documentation

template<class TYPE>
void ACE_TSS< TYPE >::dump void    const
 

Dump the state of an object.

Reimplemented in ACE_TSS_Connection.

template<class TYPE>
TYPE * ACE_TSS< TYPE >::make_TSS_TYPE void    const [virtual]
 

Hook for construction parameters.

Reimplemented in ACE_TSS_Connection.

template<class TYPE>
ACE_TSS< TYPE >::operator TYPE * void    const
 

Return or create and return the calling threads TYPE object.

template<class TYPE>
TYPE * ACE_TSS< TYPE >::operator->  
 

Use a "smart pointer" to get the thread-specific object associated with the <key_>.

template<class TYPE>
void ACE_TSS< TYPE >::operator= const ACE_TSS< TYPE > &    [protected]
 

template<class TYPE>
ACE_INLINE TYPE * ACE_TSS< TYPE >::ts_get void    const [protected]
 

Actually implements the code that retrieves the object from thread-specific storage.

template<class TYPE>
ACE_INLINE int ACE_TSS< TYPE >::ts_init void    const [protected]
 

Factors out common code for initializing TSS. This must NOT be called with the lock held...

template<class TYPE>
ACE_INLINE TYPE * ACE_TSS< TYPE >::ts_object TYPE *   
 

Set the thread-specific object for the key associated with this object.

template<class TYPE>
ACE_INLINE TYPE * ACE_TSS< TYPE >::ts_object void    const
 

Get the thread-specific object for the key associated with this object. Returns 0 if the data has never been initialized, otherwise returns a pointer to the data.
