Detailed Description

General purpose muon trigger.

The 3D match criterion is used followed by a scan of directions. For each direction, the 1D match criterion is applied. A trigger is fired when the specified minimum number of hits is detected for any of the directions.

checkTriggerBit()

template<JTriggerbit_t N>

bool JTRIGGER::JTriggerInterface::checkTriggerBit ( ) const

inlineprotectedinherited

Test whether specific trigger bit correponds to derived trigger class.

This method will be specialised using the marco setTriggerBit() so that it will return true if this triggered event corresponds to bit N.

This method will be repeatedly called by method find_trigger_bit() which in turn is called by the member method JTriggerInterface::getTriggerBit() so that it returns the correct trigger bit.

Returns

false

Definition at line 76 of file JTriggerInterface.hh.

    {
      return false;
    }

find_trigger_bit() [1/2]

template<JTriggerbit_t N>

JTriggerbit_t JTRIGGER::JTriggerInterface::find_trigger_bit ( JBit< N > bit ) const

inlineprotectedinherited

Recursive method to find the trigger bit of the given trigger data.

Parameters

bit	trigger bit

Returns

trigger bit

Definition at line 89 of file JTriggerInterface.hh.

    {

find_trigger_bit() [2/2]

JTriggerbit_t JTRIGGER::JTriggerInterface::find_trigger_bit ( JBit< NUMBER_OF_TRIGGER_BITS > bit ) const

getTriggerName() [1/2]

template<JTriggerbit_t N>

static const char * JTRIGGER::JTriggerInterface::getTriggerName ( )

inlinestaticprotectedinherited

Get trigger name.

This method will be specialised using the marco setTriggerBit() so that it will return name of trigger for bit N.

This method will be repeatedly called by method get_trigger_name() which in turn is called by the method JTriggerInterface::getTriggerName() so that it returns the correct trigger name.

Returns

NULL

Get trigger name.

param bit trigger bit

Returns

trigger name
