Detailed Description

Base class to handles to be used in lieu of naked pointers to various Gaudi components.

This allows better control through the framework of component loading, configuration and usage. This base class implements common features.

Constructor & Destructor Documentation

GaudiHandleBase::GaudiHandleBase ( std::string  myTypeAndName, std::string  myComponentType, std::string  myParentName  )

inlineprotected

Create a handle ('smart pointer') to a gaudi component.

Parameters

myTypeAndName	"MyType/MyName" ("MyType" is short for "MyType/MyType") 'MyType' is the name of the concrete class of the component 'MyName' is to distinguish several instances of the same concrete class
myComponentType	string indicating what type of component the handle is pointing to. For example: "PublicTool", "PrivateTool", "Service". This is used for printout and on the python side for type checking. On the python side there are classes with these names with "Handle" appended: PublicToolHandle,PrivateToolHandle,ServiceHandle
myParentName	Name of the parent that has this handle as a member. Used in printout.

Member Function Documentation

bool GaudiHandleBase::empty ( ) const

inline

Check if the handle has been set to empty string (i.e.

typeAndName string is empty).

Definition at line 131 of file GaudiHandle.h.

{ return m_typeAndName.empty(); }

std::string GaudiHandleBase::messageName

(

)

const

name used for printing messages

Definition at line 44 of file GaudiHandle.cpp.

{
  std::string propName = propertyName();
  if ( propName.empty() ) {
    propName = pythonPropertyClassName() + "('" + m_typeAndName + "')";
  }
  return parentName() + "." + propName;
}

std::string GaudiHandleBase::name

(

)

const

The instance name: the part after the '/'.

Definition at line 23 of file GaudiHandle.cpp.

{
  auto slash = m_typeAndName.find( '/' );
  if ( slash == std::string::npos ) {
    // only type is given, or string is empty.
    // return default name (=type or empty, in this case full string)
    return m_typeAndName;
  } else if ( slash != m_typeAndName.length() - 1 ) {
    // an explicit name is given, so return it
    return m_typeAndName.substr( slash + 1 );
  } else {
    // ends with /, i.e. explicit empty name.
    // Should probably never happen.
    return "";
  }
}

std::string GaudiHandleBase::pythonPropertyClassName ( ) const

overridevirtual

Name of the componentType with "Handle" appended.

Used as the python class name for the property in the genconf-generated configurables. The python class is defined in GaudiPython/python/GaudiHandles.py.

Implements GaudiHandleInfo.

Definition at line 42 of file GaudiHandle.cpp.

{ return componentType() + "Handle"; }

std::string GaudiHandleBase::pythonRepr ( ) const

overridevirtual

Python representation of handle, i.e.

python class name and argument. Can be used in the genconf-generated configurables. The corresponding python classes are defined in GaudiPython/GaudiHandles.py

Implements GaudiHandleInfo.

Definition at line 53 of file GaudiHandle.cpp.

{ return pythonPropertyClassName() + "('" + m_typeAndName + "')"; }

void GaudiHandleBase::setName

(

const std::string &

myName

)

Set the instance name (part after the '/') without changing the class type.

Definition at line 40 of file GaudiHandle.cpp.

{ m_typeAndName = type() + '/' + myName; }

void GaudiHandleBase::setTypeAndName

(

std::string

myTypeAndName

)

The component "type/name" string.

Definition at line 9 of file GaudiHandle.cpp.

{ m_typeAndName = std::move( myTypeAndName ); }

std::string GaudiHandleBase::type

(

)

const

The concrete component class name: the part before the '/'.

Definition at line 11 of file GaudiHandle.cpp.

{
  std::string::size_type slash = m_typeAndName.find( '/' );
  if ( slash != std::string::npos ) {
    // return only part before /
    return m_typeAndName.substr( 0, slash );
  } else {
    // return full string
    return m_typeAndName;
  }
}

std::string GaudiHandleBase::typeAndName ( ) const

inline

The full type and name: "type/name".

Definition at line 122 of file GaudiHandle.h.

{ return m_typeAndName; }
