Detailed Description

VarHandleKeyProperty is the class which wraps a SG::VarHandleKey.

The Property object refers to an instance of SG::VarHandleKey (the value object) and provides generic methods for manipulating it.

Constructor & Destructor Documentation

VarHandleKeyProperty()

SG::VarHandleKeyProperty::VarHandleKeyProperty	(	const std::string &	name,
		SG::VarHandleKey &	ref
	)

Constructor with parameters.

Parameters

name	Name of the property.
ref	Object which this property is setting (the value object).
name	Name of the property.
ref	Object which this property is setting.

Member Function Documentation

assign()

bool SG::VarHandleKeyProperty::assign ( const Gaudi::Details::PropertyBase &  source )

overridevirtual

Set the value of this Property from another.

Parameters

destination

The Property from which the value should be copied.

The value object of this source is copied to that of this Property by converting to a string and back again. Returns true on success, false on failure.

Definition at line 139 of file VarHandleKeyProperty.cxx.

{
  return fromString( source.toString() ).isSuccess();
}

clone()

VarHandleKeyProperty * SG::VarHandleKeyProperty::clone ( ) const

overridevirtual

Return a new copy of this Property object.

The new object will be associated with the same value object as the original.

Definition at line 109 of file VarHandleKeyProperty.cxx.

{
  return new VarHandleKeyProperty( *this );
}

fromString()

StatusCode SG::VarHandleKeyProperty::fromString ( const std::string &  s )

overridevirtual

Set this value object from a string.

Parameters

s	String from which to initialize the value.

Returns failure if the conversion does not succeed.

Definition at line 177 of file VarHandleKeyProperty.cxx.

{
  if (!Gaudi::Parsers::parse(*m_pValue, s).isSuccess()) {
    return StatusCode::FAILURE;
  }
  return useUpdateHandler()
    ? StatusCode::SUCCESS
    : StatusCode::FAILURE;
}

load()

bool SG::VarHandleKeyProperty::load ( Gaudi::Details::PropertyBase &  destination ) const

overridevirtual

Set the value of another Property.

Parameters

destination

The Property whose value is changed.

The value object of this Property is copied to that of destination by converting to a string and back again. Returns true on success, false on failure.

Definition at line 124 of file VarHandleKeyProperty.cxx.

{
  return destination.assign( *this );
}

operator=()

VarHandleKeyProperty & SG::VarHandleKeyProperty::operator=

(

const SG::VarHandleKey &

value

)

Assignment operator.

Parameters

value

Value from which to assign.

Copy the value object which we control from another value object.

Definition at line 95 of file VarHandleKeyProperty.cxx.

{
  setValue( value );
  return *this;
}

setValue()

bool SG::VarHandleKeyProperty::setValue

(

const SG::VarHandleKey &

value

)

Set the value object for this Property.

Parameters

value

Value from which to copy.

Return true on success; false if the update handler failed.

Definition at line 206 of file VarHandleKeyProperty.cxx.

{
  m_pValue->operator=(value);
  return useUpdateHandler();
}

toStream()

void SG::VarHandleKeyProperty::toStream ( std::ostream &  out ) const

overridevirtual

Write a string representation of the value object to a stream.

Parameters

out	Stream to which to write.

Definition at line 163 of file VarHandleKeyProperty.cxx.

{
  useReadHandler();
  out << this->toString();
}

toString()

std::string SG::VarHandleKeyProperty::toString ( ) const

overridevirtual

Return a string representation of the value object.

Definition at line 149 of file VarHandleKeyProperty.cxx.

{
  useReadHandler();
  std::ostringstream o;
  Gaudi::Utils::toStream(*m_pValue, o);
  return o.str();
}

value()

const SG::VarHandleKey & SG::VarHandleKeyProperty::value

(

)

const

Return the value object for this Property.

Definition at line 192 of file VarHandleKeyProperty.cxx.

{
  useReadHandler();
  return *m_pValue;
}

Member Data Documentation

m_pValue

SG::VarHandleKey* SG::VarHandleKeyProperty::m_pValue

private

Pointer to the real property.

Reference would be better, but Reflex does not support references yet
