A collection of FrameData structures for recently-received frames within a particular thread.
This holds the raw data as reported by the client, and it automatically handles frames received out-of-order or skipped. You can ask for a particular frame by frame number or time and receive the data for the nearest frame.

void ReferenceCount::local_object | ( | ) | [inline, inherited] |
This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.
This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

void PStatThreadData::record_new_frame | ( | int | frame_number, |
PStatFrameData * | frame_data | ||
) |
Makes room for and stores a new frame's worth of data.
Calling this function may cause old frame data to be discarded to make room, according to the amount of time set up via set_history().
The pointer will become owned by the PStatThreadData object and will be freed on destruction.
Definition at line 309 of file pStatThreadData.cxx.
References PStatFrameData::get_start(), and PStatFrameData::is_empty().
void ReferenceCount::ref | ( | ) | const [inline, inherited] |
Explicitly increments the reference count.
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

void PStatThreadData::set_history | ( | float | time | ) |

bool ReferenceCount::unref | ( | ) | const [inline, virtual, inherited] |
Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.
