def __repr__(self):

Undocumented

def __str__(self):

Returns the nicely printable string representation of this instance.

def format_as_html(self):

This method gets an html formatting string representation for this class instance.

@property
creation_transition =

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.

Note

The context after the creation_transition is always the first_context of this frame.

Information

Returns
A `reven2.trace.Transition` if known. Otherwise `None`

@property
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.

Note

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.

Information

Returns
A `reven2.trace.Context`.

@property
type =

Property: The type of the stack frame.

It indicates in which context the frame was created.

Information

Returns
A `StackFrameType`.
