addDimensionedVariable() [1/3]

StatusCode D3PD::AddVariable::addDimensionedVariable ( const std::string & name, const std::type_info & ti, void *& ptr, const std::string & dim, const std::string & docstring = "", const void * defval = 0 )

virtualinherited

Add a variable to the tuple.

Parameters

name	The name of the variable.
type	The type of the variable.
ptr	Pointer to the type of the variable. The pointer need not be initialized; the D3PD software will set the pointer prior to calling fill().
dim	Dimension for the variable. (Presently unimplemented!)
docstring	Documentation string for this variable.
defval	Pointer to the default value to use for this variable. Null for no default (generally means to fill with zeros). Of the type given by ti. Only works for basic types.

If called from the constructor, the only effect is to clear ptr.

configureD3PD() [1/2]

StatusCode D3PD::AddVariable::configureD3PD ( IAddVariable * tree )

inherited

Configure the parent tree.

Parameters

tree	The parent IAddVariable instance.

Definition at line 69 of file AddVariable.cxx.

{
  m_tree = tree;
  m_metadata.clear();
  return StatusCode::SUCCESS;
}

configureD3PD() [2/2]

virtual StatusCode D3PD::BlockFillerTool< xAOD::Photon >::configureD3PD ( IAddVariable * tree, const std::type_info & ti )

virtualinherited

Configure during initialization: type-check.

Parameters

tree	Our parent for tuple making.
ti	Gives the type of the object being passed to fillUntyped.

configureD3PD should check that the type of the object coming as input is compatible with what it expects, and raise an error otherwise.

configureImpl() [1/2]

StatusCode D3PD::BlockFillerToolImpl::configureImpl ( IAddVariable * tree, const std::type_info & ti, const std::type_info & fill_ti )

protectedinherited

Configure during initialization: type-check.

Parameters

tree	Our parent for tuple making.
ti	Gives the type of the object being passed to fillUntyped.
fill_ti	is the type of object that the user code will expect.

This is the common implementation for the configureD3PD method of IBlockFillerTool. It checks that the type of the object coming as input is compatible with what the user code is expecting, and raises an error otherwise.

Definition at line 70 of file BlockFillerToolImpl.cxx.

{
  CHECK( AddVariable::configureD3PD (tree) );
  CHECK( m_converter.init (ti, fill_ti) );
 
  return StatusCode::SUCCESS;

configureImpl() [2/2]

StatusCode D3PD::BlockFillerToolImpl::configureImpl ( IAddVariable * tree, const std::type_info & ti, const std::vector< const std::type_info * > & tis, size_t & which )

protectedinherited

Configure during initialization: type-check.

Parameters

	tree	Our parent for tuple making.
	ti	Gives the type of the object being passed to fillUntyped.
	tis	List of possible input types that we can accept.
[out]	which	Index of the accepted type.

This is the common implementation for the configureD3PD method of IBlockFillerTool. It checks that the type of the object coming as input is compatible with what the user code is expecting, and raises an error otherwise.

This version allows for one of a set of types to match. If successful, WHICH is set to the index (0-based) of the matching type.

Definition at line 91 of file BlockFillerToolImpl.cxx.

{
  CHECK( AddVariable::configureD3PD (tree) );
  CHECK( m_converter.init (ti, tis, which) );
  return StatusCode::SUCCESS;
}

convert()

StatusCode D3PD::BlockFillerToolImpl::convert ( void const *& p ) const

protectedinherited

Do type conversion.

Parameters

p[in,out]

Pointer to convert.

On entry, p is a pointer to an object of the type that was passed into configureImpl as ti. Convert the pointer to point to an object of the type that was given as fill_ti. If the conversion fails, the pointer is set to 0 (and FAILURE is returned).

Definition at line 107 of file BlockFillerToolImpl.cxx.

{
  p = m_converter.convertUntyped (p);
  if (!p) {
    REPORT_MESSAGE (MSG::ERROR)
      << "Pointer conversion from " << m_converter.srcName() << " to "
      << m_converter.dstName() << "failed.";
    return StatusCode::FAILURE;
  }
  return StatusCode::SUCCESS;
}

fill()

StatusCode D3PD::egammaConversionFillerTool::fill ( const xAOD::Photon & p )

overridevirtual

Fill one block — type-safe version.

Parameters

p	The input object.

This is called once per object. The caller is responsible for arranging that all the pointers for booked variables are set appropriately upon entry.

Parameters

p	The input object.

This is called once per object. The caller is responsible for arranging that all the pointers for booked variables are set appropriately upon entry.

FIXME: Split this up!

  }
 
  return StatusCode::SUCCESS;
}

fillAgain()

virtual StatusCode D3PD::BlockFillerTool< xAOD::Photon >::fillAgain ( const xAOD::Photon & p )

virtualinherited

Fill one block, after AGAIN has been returned (type-safe).

Parameters

p	The input object.

Once fill returns AGAIN, the parent should call fillAgain with the same arguments. This continues until fillAgain returns something other than AGAIN.

By default, this just calls fill().

fillUntyped()

virtual StatusCode D3PD::BlockFillerTool< xAOD::Photon >::fillUntyped ( const void * p, bool again = false )

virtualinherited

Fill one block.

Parameters

p	The input object.
again	Set if this is a subsequent call requested by an AGAIN return

This is called once per object. The type of the object at which p points is given by the ti argument to configureD3PD. The caller is responsible for arranging that all the pointers for booked variables are set appropriately upon entry.

If the return status is the special code AGAIN (defined above), then this filler tool wants to make multiple entries. The parent should set up to capture a new ‘row’ and run through the list of block filler tools again, but for this tool call fillAgainUntyped instead of fillUntyped. This should be repeated as long as fillAgainUntyped returns AGAIN.

Once fillUntyped returns AGAIN, the parent should call fillUntyped with the same p argument and again set to true. This continues until fillUntyped returns something other than AGAIN.

Not all parents may support this. In that case, returning AGAIN will be treated as an error.
