Detailed Description

base class to forward messages to another class

The idea is that this class should closely mirror the behavior of AsgMessaging but instead of representing a named component in its own right, it forwards all the messages to another component. This is used for things like the systematics data handles that report all their messages as part of the owning algorithm.

Constructor & Destructor Documentation

AsgMessagingForward()

template<typename T >

asg::AsgMessagingForward::AsgMessagingForward ( T *  owner )

explicit

forwarding constructor

This is templated to allow arbitrary parent classes to be passed in here using the this pointer.

Definition at line 82 of file AsgMessagingForward.h.

    : m_msg ([owner] () -> MsgStream& {return owner->msg();})
  {}

Member Function Documentation

msg() [1/2]

MsgStream & asg::AsgMessagingForward::msg

(

)

const

The standard message stream.

Returns

A reference to the default message stream of this object.

Definition at line 24 of file AsgMessagingForward.cxx.

  {
    return m_msg();
  }

msg() [2/2]

MsgStream & asg::AsgMessagingForward::msg

(

const MSG::Level

lvl

)

const

The standard message stream.

Parameters

lvl	The message level to set the stream to

Returns

A reference to the default message stream, set to level "lvl"

Definition at line 29 of file AsgMessagingForward.cxx.

  {
    MsgStream& msg = m_msg ();
    msg << lvl;
    return msg;
  }

msgLvl()

bool asg::AsgMessagingForward::msgLvl

(

const MSG::Level

lvl

)

const

Test the output level of the object.

Parameters

lvl	The message level to test against

Returns

boolean Indicting if messages at given level will be printed

true If messages at level "lvl" will be printed

Definition at line 11 of file AsgMessagingForward.cxx.

  {
    MsgStream& msg = m_msg();
    if (msg.level() <= lvl)
    {
      msg << lvl;
      return true;
    } else
    {
      return false;
    }
  }

Member Data Documentation

m_msg

std::function<MsgStream& ()> asg::AsgMessagingForward::m_msg

private

the message stream we use

This used to be a simple pointer to the MsgStream itself, but in AthenaMT the actual object used is local to the thread. So instead of pointing to it directly we are now using a function to look it up, which will get the thread-local object.
