overrideprotectedpure virtual

Return the top level TP converter (which is always used for writing)

Implemented in JetTagInfoCnv, MVFVxContainerCnv, MuonCaloEnergiesCnv, InDetTrackCnv, and MuonMeasurementsCnv.

name()

virtual const std::string T_AthenaPoolExtendingCnv::name ( ) const

overrideprotectedvirtual

Get the name of this converter (anything that identifies it).

Used for logging

Returns

Name of this converter

needsCloning()

virtual bool T_AthenaPoolExtendingCnv::needsCloning ( ) const

inlineoverrideprotectedvirtual

tells if this converter needs to be cloned (true after the converter has been registered once already)

{ return m_originalExtendingCnv != 0; }

poolReadObject() [1/2]

template<class P >

P* T_AthenaPoolExtendingCnv::poolReadObject ( )

protected

Read object of type P.

This is an exception-throwing version of poolToObject() plus reading of all extending objects. Version 1 - (see createTransient() above)

Returns

object read from POOL (by pointer) deprecated - use poolReadObject(TLPCnv)

poolReadObject() [2/2]

template<class P >

void T_AthenaPoolExtendingCnv::poolReadObject ( TopLevelTPCnvBase &  tlp_converter )

protected

Read object of type P (plus all extending objects) using the indicated top-level TP converter.

Version 2 - (see createTransient() above) NOTE: the TLP converter will delete the persistent object after createTransient()

Parameters

tlp_converter

[IN] top-level TP converter to be used when reading

readObject()

virtual void T_AthenaPoolExtendingCnv::readObject ( const std::string &  token )

inlineoverrideprotectedvirtual

Definition at line 49 of file T_AthenaPoolExtendingCnv.h.

{ this->readObjectFromPool(token); }

readObjectFromPool()

virtual void T_AthenaPoolExtendingCnv::readObjectFromPool ( const std::string &  token )

protectedpure virtual

Read the persistent object from POOL.

Parameters

token

[IN] token of the object to read

Implemented in MVFVxContainerCnv, JetTagInfoCnv, InDetTrackCnv, MuonCaloEnergiesCnv, and MuonMeasurementsCnv.

setToken()

virtual void T_AthenaPoolExtendingCnv::setToken ( const std::string &  token )

overrideprotectedvirtual

Set the token (in std::string representation) and classID for the object that will be read next.

Required by compareClassGuid() and poolReadObject(). Only extending converter needs to call this method explicitely

Parameters

token

[IN] token for the object to be read

wasClonedFrom()

virtual void T_AthenaPoolExtendingCnv::wasClonedFrom ( AthenaConverterTLPExtension *  orig_converter )

overrideprotectedvirtual

remember the original converter this one was cloned from

writeObject()

virtual std::unique_ptr<const Token> T_AthenaPoolExtendingCnv::writeObject ( const std::string &  key, const std::string &  output  )

overrideprotectedvirtual

Write the persistent object to POOL.

Parameters

key	[IN] StoreGate key (string) - placement hint to generate POOL container name
