Constructor & Destructor Documentation

◆ RNTCollectionQuery()

pool::RootCollection::RNTCollectionQuery::RNTCollectionQuery	(	const pool::ICollectionDescription &	description,
		ROOT::RNTupleReader *	reader
	)

Constructor.

◆ ~RNTCollectionQuery()

virtual pool::RootCollection::RNTCollectionQuery::~RNTCollectionQuery ( )

virtual

Destructor.

Member Function Documentation

◆ addToAttributeOutputList()

void pool::RootCollection::RNTCollectionQuery::addToAttributeOutputList ( const std::string & columnName )

protected

◆ addToTokenOutputList()

void pool::RootCollection::RNTCollectionQuery::addToTokenOutputList ( const std::string & columnName )

protected

◆ execute()

virtual pool::ICollectionCursor& pool::RootCollection::RNTCollectionQuery::execute ( )

virtual

Processes the query and returns a cursor over the query result.

Implements pool::ICollectionQuery.

◆ initMessaging()

void AthMessaging::initMessaging ( ) const

privateinherited

Initialize our message level and MessageSvc.

This method should only be called once.

Definition at line 39 of file AthMessaging.cxx.

 {
   m_imsg = Athena::getMessageSvc();
   m_lvl = m_imsg ?
     static_cast<MSG::Level>( m_imsg.load()->outputLevel(m_nm) ) :
     MSG::INFO;
 }

◆ msg() [1/2]

MsgStream & AthMessaging::msg ( ) const

inlineinherited

The standard message stream.

Returns a reference to the default message stream May not be invoked before sysInitialize() has been invoked.

Definition at line 164 of file AthMessaging.h.

 {
   MsgStream* ms = m_msg_tls.get();
   if (!ms) {
     if (!m_initialized.test_and_set()) initMessaging();
     ms = new MsgStream(m_imsg,m_nm);
     m_msg_tls.reset( ms );
   }
  
   ms->setLevel (m_lvl);
   return *ms;
 }

◆ msg() [2/2]

MsgStream & AthMessaging::msg ( const MSG::Level lvl ) const

inlineinherited

The standard message stream.

Returns a reference to the default message stream May not be invoked before sysInitialize() has been invoked.

Definition at line 179 of file AthMessaging.h.

180 { return msg() << lvl; }

◆ msgLvl()

bool AthMessaging::msgLvl ( const MSG::Level lvl ) const

inlineinherited

Test the output level.

Parameters

lvl	The message level to test against

Returns: boolean Indicating if messages at given level will be printed

Return values

true	Messages at level "lvl" will be printed

Definition at line 151 of file AthMessaging.h.

 {
   if (!m_initialized.test_and_set()) initMessaging();
   if (m_lvl <= lvl) {
     msg() << lvl;
     return true;
   } else {
     return false;
   }
 }

◆ selectAll()

virtual void pool::RootCollection::RNTCollectionQuery::selectAll ( )

virtual

Adds all Token and Attribute columns to the query select list.

Implements pool::ICollectionQuery.

◆ selectAllAttributes()

virtual void pool::RootCollection::RNTCollectionQuery::selectAllAttributes ( )

virtual

Adds all Attribute columns to the query select list.

Implements pool::ICollectionQuery.

◆ selectAllTokens()

virtual void pool::RootCollection::RNTCollectionQuery::selectAllTokens ( )

virtual

Adds all Token columns to the query select list.

Implements pool::ICollectionQuery.

◆ setLevel()

void AthMessaging::setLevel ( MSG::Level lvl )

inherited

Change the current logging level.

Use this rather than msg().setLevel() for proper operation with MT.

Definition at line 28 of file AthMessaging.cxx.

 {
   m_lvl = lvl;
 }
