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.

Examples: hexrays_sample14.cpp, hexrays_sample17.cpp, and hexrays_sample5.cpp.

Member Function Documentation

◆ contains_expr()

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

Does the item contain an expression?

Definition at line 11618 of file hexrays.hpp.

◆ contains_label()

bool citem_t::contains_label ( void ) const

Does the item contain a label?

Definition at line 11624 of file hexrays.hpp.

◆ find_closest_addr()

citem_t * citem_t::find_closest_addr ( ea_t _ea )

Examples: hexrays_sample14.cpp.

Definition at line 11636 of file hexrays.hpp.

◆ find_parent_of() [1/2]

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

Definition at line 6094 of file hexrays.hpp.

◆ find_parent_of() [2/2]

const citem_t * citem_t::find_parent_of ( const citem_t * sitem ) const

Find parent of the specified item.

Parameters

sitem 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

Examples: hexrays_sample17.cpp.

Definition at line 11630 of file hexrays.hpp.

◆ is_expr()

bool citem_t::is_expr ( void ) const

Is an expression?

Examples: hexrays_sample5.cpp.

Definition at line 6084 of file hexrays.hpp.

◆ print1()

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

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.

Definition at line 7246 of file hexrays.hpp.

◆ swap()

void citem_t::swap ( citem_t & r )

Swap two citem_t.

Definition at line 6077 of file hexrays.hpp.

References ea, label_num, and op.

Member Data Documentation

◆ ea

ea_t citem_t::ea = BADADDR

address that corresponds to the item. may be BADADDR

Examples: hexrays_sample14.cpp, hexrays_sample17.cpp, hexrays_sample3.cpp, hexrays_sample5.cpp, and hexrays_sample7.cpp.

Definition at line 6066 of file hexrays.hpp.

Referenced by swap().

◆ index

int citem_t::index = -1

mutable

an index in cfunc_t::treeitems.

meaningful only after print_func()

Definition at line 6073 of file hexrays.hpp.

◆ 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.
