Detailed Description

Action which checks if restart (sub)actions have been generated and restarts itself.

Actions or Rules can request a restart on a Funcdata object by calling setRestartPending(true) on it. This action checks for the request then resets and reruns the group of Actions as appropriate.

Member Function Documentation

◆ apply()

int4 ghidra::ActionRestartGroup::apply ( Funcdata data)
virtual

Make a single attempt to apply this Action.

This is the main entry point for applying changes to a function that are specific to this Action. The method can inspect whatever it wants to decide if the Action does or does not apply. Changes are indicated by incrementing the count field.

Parameters
datais the function to inspect/modify
Returns
0 for a complete application, -1 for a partial completion (due to breakpoint)

Reimplemented from ghidra::ActionGroup.

References ghidra::ActionGroup::apply(), ghidra::Architecture::clearAnalysis(), ghidra::Funcdata::getArch(), ghidra::Funcdata::hasRestartPending(), ghidra::Funcdata::isJumptableRecoveryOn(), ghidra::Action::status, ghidra::Action::status_start, and ghidra::Funcdata::warningHeader().

◆ clone()

Action * ghidra::ActionRestartGroup::clone ( const ActionGroupList grouplist) const
virtual

Clone the Action.

If this Action is a member of one of the groups in the grouplist, this returns a clone of the Action, otherwise NULL is returned.

Parameters
grouplistis the list of groups being cloned
Returns
the cloned Action or NULL

Reimplemented from ghidra::ActionGroup.

References ghidra::ActionGroup::addAction(), ghidra::Action::clone(), ghidra::Action::flags, and ghidra::Action::getName().

◆ reset()

void ghidra::ActionRestartGroup::reset ( Funcdata data)
virtual

Reset the Action for a new function.

Parameters
datais the new function this Action may affect

Reimplemented from ghidra::ActionGroup.
