All accessors return a pointer to the calling thread's copy of the TYPE data. The pointer may be 0 on error conditions or if the calling thread's copy of the data has not yet been set. See specific method descriptions for complete details.

This class helps to maintain a separate copy of an object for each thread that needs access to it. All threads access a single instance of ACE_TSS to obtain a pointer to a thread-specific copy of a TYPE object. Using a pointer to TYPE in TSS instead of TYPE itself is useful because, in addition to avoiding copies on what may be a complex class, it allows assignment of objects to thread-specific data that have arbitrarily complex constructors.
When the ACE_TSS object is destroyed, all threads's instances of the data are deleted.
Modern compilers have no problem using a built-in type for
TYPE. However, if you must use an older compiler that won't work with a built-in type, the ACE_TSS_Type_Adapter class template, below, can be used for adapting built-in types to work with ACE_TSS.
|ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE ACE_TSS< TYPE >::ACE_TSS||(||TYPE *|| ts_obj =
Default constructor. Can also initialize this ACE_TSS instance, readying it for use by the calling thread as well as all other threads in the process. If the constructor does not initialize this object, the first access to it will perform the initialization, which could possibly (under odd error conditions) fail.
|ts_obj||If non-zero, this object is initialized for use by all threads and ts_obj is used to set the thread-specific value for the calling thread. Other threads use the ts_object (TYPE *) method to set a specific value.|
|ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_TSS< TYPE >::~ACE_TSS||(||void||)||
Deregister this object from thread-specific storage administration. Will cause all threads' copies of TYPE to be destroyed.
|void ACE_TSS< TYPE >::dump||(||void||)||const|
Dump the state of an object.
Reimplemented in ACE_TSS_Connection.
|TYPE * ACE_TSS< TYPE >::make_TSS_TYPE||(||void||)|| const
Hook for construction parameters.
Reimplemented in ACE_TSS_Connection.
|ACE_TSS< TYPE >::operator TYPE *||(||void||)||const|
Obtain a pointer to the calling thread's TYPE object. If this ACE_TSS object hasn't been initialized, this method will initialize it as a side-affect. If the calling thread has not set a value, a default-constructed instance of TYPE is allocated and it becomes the thread's instance.
|TYPE * ACE_TSS< TYPE >::operator->||(||)||const|
Use a "smart pointer" to get the thread-specific data associated with this object. If this ACE_TSS object hasn't been initialized, this method will initialize it as a side-affect. If the calling thread has not set a value, a default-constructed instance of TYPE is allocated and it becomes the thread's instance.
|ACE_INLINE TYPE * ACE_TSS< TYPE >::ts_get||(||void||)|| const
Actually implements the code that retrieves the object from thread-specific storage.
|ACE_INLINE int ACE_TSS< TYPE >::ts_init||(||void||)||
Factors out common code for initializing TSS. This must NOT be called with the lock held...
|ACE_INLINE TYPE * ACE_TSS< TYPE >::ts_object||(||void||)||const|
Get the thread-specific object for this object.
|ACE_INLINE TYPE * ACE_TSS< TYPE >::ts_object||(||TYPE *||new_ts_obj||)|
Set the thread-specific object for the calling thread. If this object has not been initialized yet, this method performs the initialization.
|new_ts_obj||The new value for the calling thread's copy of this object.|
