question: public boolean request ( InterruptRequest interruptRequest ) { FrInterruptRequest newInterruptRequest = ( FrInterruptRequest ) interruptRequest ; synchronized ( interruptRequestQueue ) { for ( InterruptRequest currentInterruptRequest : interruptRequestQueue ) { FrInterruptRequest currentFrInterruptRequest = ( FrInterruptRequest ) currentInterruptRequest ; if ( currentFrInterruptRequest . getInterruptNumber ( ) == newInterruptRequest . getInterruptNumber ( ) ) { if ( ( newInterruptRequest . isNMI ( ) && ! currentFrInterruptRequest . isNMI ( ) ) || ( newInterruptRequest . getICR ( ) < currentFrInterruptRequest . getICR ( ) ) ) { interruptRequestQueue . remove ( currentFrInterruptRequest ) ; break ; } else { return false ; } } } interruptRequestQueue . add ( newInterruptRequest ) ; Collections . sort ( interruptRequestQueue ) ; return true ; } }
target:  This is a way to cause completely custom (or even bogus) InterruptRequests
