Constructor & Destructor Documentation

__init__()

__init__	(		self,
		int	_flags )

Reimplemented in cfunc_parentee_t, and ctree_parentee_t.

Member Function Documentation

__disown__()

__disown__

(

self

)

Reimplemented in cfunc_parentee_t, and ctree_parentee_t.

apply_to()

int apply_to	(		self,
		'citem_t'	item,
		'citem_t'	parent )

Traverse ctree. The traversal will start at the specified item and continue until of one the visit_...() functions return a non-zero value. 

@param item: root of the ctree to traverse
@param parent: parent of the specified item. can be specified as nullptr.
@returns 0 or a non-zero value returned by a visit_...() function

apply_to_exprs()

int apply_to_exprs	(		self,
		'citem_t'	item,
		'citem_t'	parent )

Traverse only expressions. The traversal will start at the specified item and continue until of one the visit_...() functions return a non-zero value. 

@param item: root of the ctree to traverse
@param parent: parent of the specified item. can be specified as nullptr.
@returns 0 or a non-zero value returned by a visit_...() function

clr_prune()

None clr_prune

(

self

)

Do not prune children. This is an internal function, no need to call it.

clr_restart()

None clr_restart

(

self

)

Do not restart. This is an internal function, no need to call it.

is_postorder()

bool is_postorder

(

self

)

Should the leave...() functions be called?

leave_expr()

int leave_expr	(		self,
		'cexpr_t'	arg0 )

Visit an expression after having visited its children. This is a visitor function which should be overridden by a derived class to do some useful work. This visitor performs post-order traserval, i.e. an item is visited after its children. 

@returns 0 to continue the traversal, nonzero to stop.

leave_insn()

int leave_insn	(		self,
		'cinsn_t'	arg0 )

Visit a statement after having visited its children. This is a visitor function which should be overridden by a derived class to do some useful work. This visitor performs post-order traserval, i.e. an item is visited after its children. 

@returns 0 to continue the traversal, nonzero to stop.

maintain_parents()

bool maintain_parents

(

self

)

Should the parent information by maintained?

must_prune()

bool must_prune

(

self

)

Should the traversal skip the children of the current item?

must_restart()

bool must_restart

(

self

)

Should the traversal restart?

only_insns()

bool only_insns

(

self

)

Should all expressions be automatically pruned?

parent_expr()

'cexpr_t *' parent_expr

(

self

)

Get parent of the current item as an expression.

parent_insn()

'cinsn_t *' parent_insn

(

self

)

Get parent of the current item as a statement.

prune_now()

None prune_now

(

self

)

Prune children. This function may be called by a visitor() to skip all children of the current item. 

set_restart()

None set_restart

(

self

)

Restart the travesal. Meaningful only in apply_to_exprs()

visit_expr()

int visit_expr	(		self,
		'cexpr_t'	arg0 )

Visit an expression. This is a visitor function which should be overridden by a derived class to do some useful work. This visitor performs pre-order traserval, i.e. an item is visited before its children. 

@returns 0 to continue the traversal, nonzero to stop.

visit_insn()

int visit_insn	(		self,
		'cinsn_t'	arg0 )

Visit a statement. This is a visitor function which should be overridden by a derived class to do some useful work. This visitor performs pre-order traserval, i.e. an item is visited before its children. 

@returns 0 to continue the traversal, nonzero to stop.
