Detailed Description

Abstract base class for implementing RCW threads.

Users should override setup, compute, and finalize, but should not override the init, run, and cleanup functions from BaseThread

Definition at line 40 of file RCWThread.h.

Constructor & Destructor Documentation

virtual madara::threads::RCWThread::~RCWThread ( )

inlinevirtual

Destructor.

Definition at line 46 of file RCWThread.h.

Member Function Documentation

void RCWThread::cleanup ( void  )

finaloverrideprivatevirtual

Cleans up any thread residue (usually instances created in init).

It's important to note that the only things that would need to be cleaned up are generally ports opened, memory initialized with new/malloc, etc. Anything MADARA related is generally cleaned up for you.

Reimplemented from madara::threads::BaseThread.

Definition at line 20 of file RCWThread.cpp.

virtual void madara::threads::RCWThread::compute ( const knowledge::rcw::Transaction &  )

pure virtual

Executes the compute porition of a read-compute-write loop.

virtual void madara::threads::RCWThread::finalize ( knowledge::rcw::Transaction &  )

inlinevirtual

Cleans up any thread residue (usually instances created in setup).

It's important to note that the only things that would need to be cleaned up are generally ports opened, memory initialized with new/malloc, etc. Anything MADARA related is generally cleaned up for you.

Definition at line 76 of file RCWThread.h.

void RCWThread::init ( knowledge::KnowledgeBase &  kb )

finaloverrideprivatevirtual

Initializes thread with a MADARA context.

Parameters

kb	the knowledge base to interact with

Reimplemented from madara::threads::BaseThread.

Definition at line 7 of file RCWThread.cpp.

virtual void madara::threads::BaseThread::init_control_vars ( knowledge::KnowledgeBase &  control )

inlineprotectedvirtualinherited

Initializes the Java thread implementation's control plane variables.

Parameters

control

the control plane between Threader and threads

Reimplemented in madara::threads::JavaThread.

Definition at line 86 of file BaseThread.h.

void RCWThread::run ( void  )

finaloverrideprivatevirtual

Executes the main thread logic.

In a BaseThread, the execute is called once. Afterwards, cleanup is called.

Implements madara::threads::BaseThread.

Definition at line 13 of file RCWThread.cpp.

virtual void madara::threads::RCWThread::setup ( knowledge::rcw::Transaction &  )

inlinevirtual

Setup the thread for later read-compute-write loops.

Definition at line 60 of file RCWThread.h.
