CPhysicsEventItem(size_t maxBody = 8192);
Constructs an item for a single physics trigger.
Note that the storage size is statically allocated
with maxBody bytes of payload
data. The ring item header type field is initialized
to PHYSICS_EVENT.
Upon creating the item, if a body header
is required, setBodyHeader
is invoked. getBodyCursor
is then used get a pointer into the object at where
the physics data should be put. After incrementing
this pointer by an appopriate amount,
calls to setBodyCursor,
folowed by updateSize
are required to set the size field of the
ring item header.
const virtual std::string typeName();
Returns a string that represents the ring item type: Event
const virtual std::string toString();
Returns a string that represents the contents of the event. This is used, e.g., by the dumper command to render human readable data.
const virtual void* getBodyHeader();
Returns a pointer to the body header for the event.
If the event has no body header,
nullptr is returned. Note that
the base class hasBodyHeader
can be called to determine if the ring item type has
a body header.
virtual void setBodyHeader(uint64_t timestamp, uint32_t sourceId, uint32_t barrierType = 0);
Inserts a new or modifies an existing body header of the event.
