Constructor & Destructor Documentation

TimerQueryContext()

TimerQueryContext::TimerQueryContext ( int pstats_index )

inline

Member Function Documentation

force_init_type()

virtual TypeHandle TimerQueryContext::force_init_type ( )

inlinevirtual

Reimplemented from QueryContext.

Definition at line 48 of file timerQueryContext.h.

get_class_type()

static TypeHandle TimerQueryContext::get_class_type ( )

inlinestatic

Definition at line 37 of file timerQueryContext.h.

get_timestamp()

double TimerQueryContext::get_timestamp ( ) const

pure virtual

Returns the timestamp that is the result of this timer query.

There's no guarantee about which clock this uses, the only guarantee is that subtracting a start time from an end time should yield a time in seconds. If is_answer_ready() did not return true, this function may block before it returns.

It is only valid to call this from the draw thread.

inlinevirtual

Reimplemented from QueryContext.
