Member Function Documentation

DeclareInterfaceID()

IProperty::DeclareInterfaceID	(	IProperty	,
		3	,
		0	)

InterfaceID.

getProperties()

virtual const std::vector< Gaudi::Details::PropertyBase * > & IProperty::getProperties ( ) const

pure virtual

Get list of properties.

getProperty() [1/3]

virtual StatusCode IProperty::getProperty ( Gaudi::Details::PropertyBase * p ) const

pure virtual

Get the property by property.

getProperty() [2/3]

virtual StatusCode IProperty::getProperty ( std::string_view n, std::string & v ) const

pure virtual

Get the property by std::string.

getProperty() [3/3]

virtual const Gaudi::Details::PropertyBase & IProperty::getProperty ( std::string_view name ) const

pure virtual

Get the property by name.

hasProperty()

virtual bool IProperty::hasProperty ( std::string_view name ) const

pure virtual

Return true if we have a property with the given name.

setProperty() [1/6]

StatusCode IProperty::setProperty ( const Gaudi::Details::PropertyBase & p )

inline

Set the property from a property.

Definition at line 38 of file IProperty.h.

{ return setProperty( p.name(), p ); }

setProperty() [2/6]

StatusCode IProperty::setProperty ( const std::string & name, const char * v )

inline

Special case for string literals.

Definition at line 46 of file IProperty.h.

{ return setProperty( name, std::string{ v } ); }

setProperty() [3/6]

virtual StatusCode IProperty::setProperty ( const std::string & name, const Gaudi::Details::PropertyBase & p )

pure virtual

Set the property from a property with a different name.

setProperty() [4/6]

StatusCode IProperty::setProperty ( const std::string & name, const std::string & v )

inline

Special case for std::string.

Definition at line 48 of file IProperty.h.

                                                                      {
    if ( !hasProperty( name ) ) return StatusCode::FAILURE;
    return setPropertyRepr( name, v );
  }

setProperty() [5/6]

template<class TYPE>
requires ( !std::is_base_of_v<Gaudi::Details::PropertyBase, TYPE> )

StatusCode IProperty::setProperty ( const std::string & name, const TYPE & value )

inline

set the property form the value

std::vector<double> data = ... ;
setProperty( "Data" , data ) ;
 
std::map<std::string,double> cuts = ... ;
setProperty( "Cuts" , cuts ) ;
 
std::map<std::string,std::string> dict = ... ;
setProperty( "Dictionary" , dict ) ;

Note: the interface IProperty allows setting of the properties either directly from other properties or from strings only

This is very convenient in resetting of the default properties in the derived classes.

Parameters

name	name of the property
value	value of the property

setProperty() [6/6]

virtual StatusCode IProperty::setProperty ( const std::string & s )
