Detailed Description

template<class T>
class SG::WriteDecorHandleKey< T >

Property holding a SG store/key/clid/attr name from which a WriteDecorHandle is made.

This class holds the key part of a WriteDecorHandle.

Use this to add a decoration to an object such that the scheduler is aware of it. This is used just like a WriteHandleKey (which see) except that the key string is of the form CCC.DDD, where CCC is the name of the container in StoreGate and DDD is the name of the decoration.

Example:

class MyAlgorithm : public AthReentrantAlgorithm {
  ...
  SG::WriteDecorHandleKey<MyCont> m_key{this, "Key",  "container.decor"};
};
 
StatusCode MyAlgorithm::initialize()
{
  ATH_CHECK( m_key.initialize() );
  ...
}
 
StatusCode MyAlgorithm::execute (const EventContext& ctx) const
{
  SG::WriteDecorHandle<MyCont, float> h (m_key, ctx);
  for (const MyObj& o : *h) {  // Access the container.
    h (o) = calculate (o);  // Add the decoration.
    ...

Alternatively, one can construct the key with an additional VarHandleKey that represents the container and the key then only holds the decoration name. This is useful to avoid hard-coding the container name twice in case the algorithm also has a ReadHandleKey or WriteHandleKey for the container:

Example:

class MyAlgorithm : public AthReentrantAlgorithm {
  ...
  SG::WriteHandleKey<MyCont> m_whkey{this, "WHKey", "container"};
  SG::WriteDecorHandleKey<MyCont> m_wdhkey{this, "Key", m_whkey, "decor"};
};
...

Implementation note: We want to make two dependencies from this key: a read dependency on the container itself, and a write dependency on the decoration. This class derives from WriteHandleKey, which provides the output dependency on the decoration. We also hold as a member a ReadHandleKey for the container. This extra dependency is added at initialize time via registerWriteDecorHandleKey(), which see.

Member Function Documentation

assign()

template<class T >

virtual StatusCode SG::WriteDecorHandleKey< T >::assign ( const std::string &  sgkey )

overridevirtual

Change the key of the object to which we're referring.

Parameters

sgkey

The StoreGate key for the object.

The provided key may actually start with the name of the store, separated by a "+": "MyStore+Obj". If no "+" is present the store is not changed. A key name that starts with a slash is interpreted as a hierarchical key name, not an empty store name.

Returns failure the key string format is bad.

Reimplemented from SG::VarHandleKey.

CLID SG::VarHandleKey::clid ( ) const

inherited

Return the class ID for the referenced object.

  return Gaudi::DataHandle::fullKey().clid();
}

contHandleKey()

template<class T >

const ReadHandleKey<T>& SG::WriteDecorHandleKey< T >::contHandleKey

(

)

const

Return the handle key for the container.

contHandleKey_nc()

template<class T >

ReadHandleKey<T>& SG::WriteDecorHandleKey< T >::contHandleKey_nc ( )

empty()

bool SG::VarHandleKey::empty ( ) const

inherited

Return the hashed StoreGate key.

May be 0 if not yet initialized.

initialize() [1/2]

StatusCode SG::VarHandleKey::initialize ( AllowEmptyEnum  )

inherited

If this object is used as a property, then this should be called during the initialize phase.

This variant will allow the key to be blank.

Parameters

Flag	to select this variant. Call like ATH_CHECK( key.initialize (SG::AllowEmpty) );

Definition at line 129 of file AthToolSupport/AsgDataHandles/Root/VarHandleKey.cxx.

{
  if (key().empty()) {
    return StatusCode::SUCCESS;
  }
  return initialize (true);
}

initialize() [2/2]

template<class T >

StatusCode SG::WriteDecorHandleKey< T >::initialize

(

bool

used = true

)

If this object is used as a property, then this should be called during the initialize phase.

It will fail if the requested StoreGate service cannot be found or if the key is blank.

Parameters

used	If false, then this handle is not to be used. Instead of normal initialization, the key will be cleared.

owningHandle()

VarHandleBase* SG::VarHandleKey::owningHandle ( )

inherited

Return the VarHandle that owns this key, if any.

This should only be non-null for keys that are created automatically by a VarHandle when it is not created from a VarHandleKey. This should always be null for keys that are created explicitly.

parseKey()

void SG::VarHandleKey::parseKey ( const std::string &  key, const std::string &  storeName  )

privateinherited

Parameters

sgkey

The provided key may actually start with the name of the store, separated by a "+": "MyStore+Obj". If no "+" is present, the store named by storeName is used. A key name that starts with a slash is interpreted as a hierarchical key name, not an empty store name.

see implementation comments for further details

Parameters

sgkey

The StoreGate key for the referenced object.

The provided key may actually start with the name of the store, separated by a "+": "MyStore+Obj". If no "+" is present the store named by storeName is used. A key name that starts with a slash is interpreted as a hierarchical key name, not an empty store name.

we also have to check that if the key contains the store name, it matches the store name that they Handle was constructed with

blank keys result in blank DataObjIDs

pythonRepr()

template<class T >

virtual std::string SG::WriteDecorHandleKey< T >::pythonRepr ( ) const

overrideprivatevirtual

Python representation of Handle.

Reimplemented from SG::VarHandleKey.

renounce()

template<class T >

void SG::WriteDecorHandleKey< T >::renounce

(

)

Declare that this item does not participate in scheduling.

If a WriteDataHandleKey is renounced, then we skip creating the output alias. Further, we skip the check that the element provided is a member of the declared container. A WriteDataHandle initialized from a renounced key will effectively behave like a simple Decorator.

renounced()

template<class T >

bool SG::WriteDecorHandleKey< T >::renounced

(

)

const

Return the renounced flag.

setKey()

void SG::VarHandleKey::setKey ( DataObjID  key )

finaloverrideprivatevirtualinherited

Don't allow calling these.

Prevent this method from being called.

Definition at line 186 of file StoreGate/src/VarHandleKey.cxx.

{
  throw SG::ExcForbiddenMethod ("VarHandleKey::setKey");
}

setOwningHandle()

void SG::VarHandleKey::setOwningHandle ( VarHandleBase *  handle )

privateinherited

start()

virtual StatusCode SG::VarHandleKey::start ( )

virtualinherited

Called by the owning algorithm during the START transition.

AthAlgorithm and friends will call this during START. This allows for extra initialization that we can't do during initialize(), such as retrieving a conditions container from the store.

The default implementation is a no-op.
