Oracle Coherence for C++ API: ThreadLocalReference Class Reference

Detailed Description

Object

A single native thread-local is used to manage all ThreadLocalReferences, which means that users are free to allocate any number of ThreadLocalReferences.

The memory associated with a thread's ThreadLocals is automatically freed when then thread terminates. The memory associated with a non-static ThreadLocalReference will be automatically freed at some point after the ThreadLocalReference has been reclaimed, and is done in such a way that repeated creation and destruction of ThreadLocalReferences will not leak memory.

Public Types

typedef spec::Handle

Handle

ThreadLocalReference Handle definition.

typedef spec::View

View

ThreadLocalReference View definition.

typedef spec::Holder

Holder

ThreadLocalReference Holder definition.

Public Member Functions

virtual void

toStream (std::ostream &out) const

Output a human-readable description of this Object to the given stream.

coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toStream method, to output Objects. If a managed String object is desired, the COH_TO_STRING macro can be used to build up a String from streamable contents.

 Object::View vKey   = ...
 Object::View vValue = ...
 std::cout << vKey << " = " << vValue << std::endl;

 String::Handle hs = COH_TO_STRING(vKey << " = " << vValue);

Parameters:

out

the stream used to output the description

virtual void

set (Object::Holder hObject)

Specify the Object to be referenced by the calling thread.

virtual Object::Holder

get () const

Return a Holder to the calling threads referenced Object, or NULL if none has been set for the thread.

virtual Object::Holder

get ()

Return a Holder to the calling threads referenced Object, or NULL if none has been set for the thread.
