Detailed Description

Basic ctree item.

This is an abstract class (but we don't use virtual functions in ctree, so the compiler will not disallow you to create citem_t instances). However, items of pure citem_t type must never be created. Two classes, cexpr_t and cinsn_t are derived from it.

citem_t()

citem_t::citem_t ( ctype_t o = cot_empty )

inline

~citem_t()

citem_t::~citem_t ( )

Member Function Documentation

swap()

void citem_t::swap ( citem_t & r )

inline

Swap two citem_t.

is_expr()

bool citem_t::is_expr ( ) const

inline

Is an expression?

contains_expr()

bool citem_t::contains_expr ( const cexpr_t * e ) const

inline

Does the item contain an expression?

contains_label()

bool citem_t::contains_label ( ) const

inline

Does the item contain a label?

find_parent_of() [1/2]

const citem_t * citem_t::find_parent_of ( const citem_t * item ) const

inline

Find parent of the specified item.

Parameters

item	Item to find the parent of. The search will be performed among the children of the item pointed by this.

Returns

nullptr if not found

find_parent_of() [2/2]

citem_t * citem_t::find_parent_of ( const citem_t * item )

inline

find_closest_addr()

citem_t * citem_t::find_closest_addr ( ea_t _ea )

inline

print1()

void citem_t::print1 ( qstring * vout, const cfunc_t * func ) const

inline

Print item into one line.

Parameters

vout	output buffer
func	parent function. This argument is used to find out the referenced variable names.

Returns

length of the generated text.

Member Data Documentation

ea

ea_t citem_t::ea = BADADDR

address that corresponds to the item. may be BADADDR

op

ctype_t citem_t::op

item type

label_num

int citem_t::label_num = -1

label number.

-1 means no label. items of the expression types (cot_...) should not have labels at the final maturity level, but at the intermediate levels any ctree item may have a label. Labels must be unique. Usually they correspond to the basic block numbers.

index

int citem_t::index = -1

mutable

an index in cfunc_t::treeitems.

meaningful only after print_func()
