Database of root Action objects that can be used to transform a function.
This is a container for Action objects. It also manages root Action objects, which encapsulate a complete transformation system that can be applied to functions. Root Action objects are derived from a single universal Action object that has every possible sub-action within it. A root Action has its own name and is derived from the universal via a grouplist, which lists a particular subset of Action and Rule groups to use for the root. A new root Action is created by providing a new grouplist via setGroup() or modifying an existing grouplist. This class is intended to be instantiated as a singleton and keeps track of the current root Action, which is the one that will be actively applied to functions.
bool ActionDatabase::addToGroup | ( | const string & | grp, |
const string & | basegroup | ||
) |
Add a group to a root Action.
Add a group to the grouplist for a particular root Action. Do not use to redefine a root Action that has already been instantiated.
grp | is the name of the root Action |
basegroup | is the group to add |
References ActionGroupList::list.
|
private |
Set up descriptions of preconfigured root Actions.
(Re)build the default root Actions: decompile, jumptable, normalize, paramid, register, firstpass
void ActionDatabase::cloneGroup | ( | const string & | oldname, |
const string & | newname | ||
) |
Clone a root Action.
Copy an existing root Action by copying its grouplist, giving it a new name. This is suitable for a copy then modify strategy to create a new root Action. Do not use to redefine a root Action that has already been instantiated
oldname | is the name of an existing root Action |
newname | is the name of the copy |

Derive a root Action.
Internal method to build the Action object corresponding to a root Action The new Action object is created by selectively cloning components from an existing object based on a grouplist.
baseaction | is the name of the model Action object to derive from |
grp | is the name of the grouplist steering the clone |

bool ActionDatabase::removeFromGroup | ( | const string & | grp, |
const string & | basegrp | ||
) |
Remove a group from a root Action.
The group is removed from the grouplist of a root Action. Do not use to redefine a root Action that has already been instantiated.
grp | is the name of the root Action |
basegrp | is the group to remove |
References ActionGroupList::list.
void ActionDatabase::resetDefaults | ( | void | ) |
(Re)set the default configuration
Clear out (possibly altered) root Actions. Reset the default groups. Set the default root action "decompile"
Action * ActionDatabase::setCurrent | ( | const string & | actname | ) |
Set the current root Action.
The Action is specified by name. A grouplist must already exist for this name. If the Action doesn't already exist, it will be derived from the universal action via this grouplist.
actname | is the name of the root Action |

void ActionDatabase::setGroup | ( | const string & | grp, |
const char ** | argv | ||
) |
Establish a new root Action.
(Re)set the grouplist for a particular root Action. Do not use this routine to redefine an existing root Action.
grp | is the name of the root Action |
argv | is a list of static char pointers, which must end with a NULL pointer, or a zero length string. |
References ActionGroupList::list.
Action * ActionDatabase::toggleAction | ( | const string & | grp, |
const string & | basegrp, | ||
bool | val | ||
) |
Toggle a group of Actions with a root Action.
A particular group is either added or removed from the grouplist defining a particular root Action. The root Action is then (re)derived from the universal
grp | is the name of the root Action |
basegrp | is name of group (within the grouplist) to toggle |
val | is true if the group should be added or false if it should be removed |

void ActionDatabase::universalAction | ( | Architecture * | conf | ) |
Build the universal action.
Construct the universal Action that contains all possible components
conf | is the Architecture that will use the Action |
