## Member Enumeration Documentation

### enum Vector::BLF::ObjectHeader2::ObjectFlags : uint32\_t

enumeration for objectFlags

**Enumerator**

- ***TimeTenMics***

  10 micro second timestamp Object time stamp is saved as multiple of ten microseconds. (BL\_OBJ\_FLAG\_TIME\_TEN\_MICS)

- ***TimeOneNans***

  1 nano second timestamp Object time stamp is saved in nanoseconds. (BL\_OBJ\_FLAG\_TIME\_ONE\_NANS)

### enum Vector::BLF::ObjectHeader2::TimeStampStatus : uint8\_t

enumeration for timeStampStatus

**Enumerator**

- ***Orig***

  1: valid orig. timestamp Determines whether original timestamp member is valid (1) or not (0).

- ***SwHw***

  1: sw generated ts; 0: hw Timestamp is generated by software (1) or by hardware (0).

- ***User***

  protocol specific meaning This bit has protocol specific meaning.
