void HDET::ClearErrorMessage ( void )

Definition at line 75 of file HDET.h.

void HDET::DumpBinary	(	const uint32_t *	iptr,
		const uint32_t *	iend,
		uint32_t	MaxWords = `0`,
		const uint32_t *	imark = `NULL`
	)

This is used for debugging. It will print to the screen the words starting at the address given by iptr and ending just before iend or for MaxWords words, whichever comes first. If iend is NULL, then MaxWords will be printed. If MaxWords is zero then it is ignored and only iend is checked. If both iend==NULL and MaxWords==0, then only the word at iptr is printed.

bool HDET::read	(	uint32_t *&	buff,
		uint32_t &	buff_len,
		bool	allow_swap
	)

Read an event from the connected ET system. One ET event may contain multiple EVIO events. This method needs to return a single event in the given buffer (or a non-zero error code). To accomodate this, a single ET event is placed into multiple buffers so subsequent calls to this method can return one of those until another ET read is needed.

Note that the buff and bufflen parameters passed in here are references to the buffer in the worker thread that will be assigned to this event. In order to save time, we swap that buffer with one from our pool. Pool buffers are grown in size as needed to hold events as they are copied from the ET event.
