Detailed Description

A Flag is an ordered collection of bits (vector<bool>) that can hold additional (boolean) information about a trigger object. This information can be stored by a Hypo algorithm, together with the trigger object in the same TE. Since trigger objects are often stored within a container in the TE, the TrigPassFlags class acts a container for the corresponding flags.

Note that all flags witin a TrigPassFlags object have to be of the same size (given as parameter flagSize in the constructor)

Warning:

Hypo algorithms should use the helper functions (see below) to modify the TrigPassFlags content

Constructor & Destructor Documentation

TrigPassFlags::TrigPassFlags	(	const unsigned int	size,
		const unsigned int	flagSize,
		const void *	cont = 0
	)

Constructor to be used by the HLT algorithms Initialized the flags vector.

Parameters:

	size	the size of container for which the flags will be recorded. This determines the length of the outer vector<vector<bool> > of m_flagsPerObject.
	flagSize	the size of the flags. This determines the length of the inner vector<bool> m_flagsPerObject.
	cont	pointer to the container, if given then the member functions will be performing additional check if the bits setting is the same (desired initailly container)

Member Function Documentation

const std::vector< bool > & TrigPassFlags::getFlag

(

const unsigned int

position

)

const

Returns the flag (vector<bool>) at index position.

Warning:

Hypo algorithms should use the helper function HLT::getFlag (see below) to access the TrigPassFlags

bool TrigPassFlags::getFlagBit	(	const unsigned int	position,
		const unsigned int	bitPosition
	)			const

Returns the bit 'bitPosition' of the flag at index position.

Warning:

Hypo algorithms should use the helper function HLT::getFlagBit (see below) to access the TrigPassFlags

void TrigPassFlags::setFlag	(	const unsigned int	position,
		const std::vector< bool > &	flag,
		const void *	cont = 0
	)

Set the flag at index position.

Parameters:

	position	postion of the flag in the vector of flags
	flagValue	value of the flag (can be used if flagSize is smaller than sizeof(int)

Warning:

Hypo algorithms should use the helper function HLT::setFlag (see below) to modify the TrigPassFlags

void TrigPassFlags::setFlagBit	(	const unsigned int	position,
		const unsigned int	bitPosition,
		const bool	bitValue,
		const void *	cont = 0
	)

Set bit of the flag at index position.

Parameters:

	position	postion of the flag in the vector of flags
	bitPosition	position of the bit within the flag
	bitValue	enable/disable the bit

Warning:

Hypo algorithms should use the helper function HLT::setFlagBit (see below) to modify the TrigPassFlags
