virtual

Adds a column to the query select list.

Parameters

columnName Name of Attribute column to select.

Implements pool::ICollectionQuery.

◆ addToOutputList() [2/2]

virtual void pool::RootCollection::RNTCollectionQuery::addToOutputList ( const std::vector< std::string > & columnNames )

virtual

Adds one or more columns to the query select list.

Parameters

columnNames Names of Attribute columns to select.

Implements pool::ICollectionQuery.

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.

◆ setCondition()

virtual void pool::RootCollection::RNTCollectionQuery::setCondition	(	const std::string &	whereClause,
		coral::AttributeList *	attributeBindData = `0`,
		TokenList *	tokenBindData = `0`
	)

virtual

Sets the query.

the query can be constructed in fragments by repeated calls to ‘setCondition’.

Parameters

whereClause	The query.
attributeBindData	- unused
tokenBindData	- unused

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;
 }

◆ setRowCacheSize()

virtual void pool::RootCollection::RNTCollectionQuery::setRowCacheSize ( int rowCacheSize )

virtual

Sets the cache size used to store the query result.

Parameters

Number of rows stored in cache before cache is flushed.

Implements pool::ICollectionQuery.

◆ skipEventReference()

virtual void pool::RootCollection::RNTCollectionQuery::skipEventReference ( bool = true )

virtual

Tell the query to not include the primary event reference in the result by default (it can still beselected manually)

Parameters

skip	if true (the default) then skip the primary event reference

Reimplemented from pool::ICollectionQuery.

◆ whereClause()

virtual const std::string& pool::RootCollection::RNTCollectionQuery::whereClause ( ) const

virtual

Returns the where clause of the query.

Implements pool::ICollectionQuery.
