| Method | type | Property: The type of the stack frame. |
| Method | first_context | Property: The first context refers to the context where the frame is first seen in the trace on top of the active stack. |

| Method | __str__ | Information =========== |

Property: The type of the stack frame.
It indicates in which context the frame was created.
| Returns | A StackFrameType. | |
Property: The first context refers to the context where the frame is first seen in the trace on top of the active stack.
While the transition before the first_context
will generally be the creation_transition
of this frame, sometimes it is not the case because e.g. the frame was
created before the beginning of the trace (Unknown frame),
or its stack was manipulated (Damaged frame). In that case,
the transition before the first_context
will typically be a return to this already existing frame.
| Returns | A reven2.trace.Context. | |
Property: The transition that lead to the creation of the frame.
Sometimes this transition is unknown because e.g. the frame was created
before the beginning of the trace (Unknown frame) or its stack
was manipulated (Damaged frame). In these cases,
None will be returned.
The context after the creation_transition
is always the first_context
of this frame.
| Returns | A reven2.trace.Transition
if known. Otherwise None | |
