Construct a SignalInvocationHint struct initialized to zero.

Methods

The detail passed on for this emission

Get the value of the “detail” field. When overloading is enabled, this is equivalent to

get signalInvocationHint #detail

Set the value of the “detail” field. When overloading is enabled, this is equivalent to

set signalInvocationHint [ #detail := value ]

The stage the signal emission is currently in, this field will contain one of SignalFlagsRunFirst, SignalFlagsRunLast or SignalFlagsRunCleanup and SignalFlagsAccumulatorFirstRun. SignalFlagsAccumulatorFirstRun is only set for the first run of the accumulator function for a signal emission.

Get the value of the “run_type” field. When overloading is enabled, this is equivalent to

get signalInvocationHint #runType

Set the value of the “run_type” field. When overloading is enabled, this is equivalent to

set signalInvocationHint [ #runType := value ]

The signal id of the signal invoking the callback

Get the value of the “signal_id” field. When overloading is enabled, this is equivalent to

get signalInvocationHint #signalId

Set the value of the “signal_id” field. When overloading is enabled, this is equivalent to

set signalInvocationHint [ #signalId := value ]
