This inheritance list is sorted roughly, but not completely, alphabetically:

[detail level 12]

Ctheo::decomp::decomp_t	the main decomposition class which is responsible for breaking down lib file into coff files, and extracted used symbols from the coff files.
Ctheo::obf::engine_t	singleton obfuscation engine class. this class is responsible for keeping track of the registered passes and the order in which to execute them.
▼Ctheo::obf::transform::operation_t	operation_t is the base class for all types of transformations. classes that inherit this class are singleton and simply call the super constructor (operation_t::operation_t).
Ctheo::obf::transform::add_op_t
Ctheo::obf::transform::rol_op_t
Ctheo::obf::transform::ror_op_t
Ctheo::obf::transform::sub_op_t
Ctheo::obf::transform::xor_op_t
▼Ctheo::obf::pass_t	the pass_t class is a base clase for all passes made. you must override the pass_t::run virtual function and declare the logic of your pass there
Ctheo::obf::hello_world_pass_t	hello world pass example of how to inherit pass_t.
Ctheo::obf::jcc_rewrite_pass_t	jcc rewrite pass which rewrites rip relative jcc's so that they are position independent
Ctheo::obf::next_inst_pass_t	This pass is used to generate transformations and jmp code to change RIP to the next instruction
Ctheo::obf::reloc_transform_pass_t	this pass is like the next_inst_pass, however, relocations are encrypted with transformations instead of the address of the next instruction. this pass only runs at the instruction level and appends transformations into the reloc_t object of the instruction symbol
Ctheo::recomp::recomp_t	the main class responsible for recomposition
Ctheo::recomp::reloc_t	meta data about a relocation for a symbol
Ctheo::decomp::routine_t	the routine class which is responsible for creating symbols for routines. if the routine is located inside a section with the name ".split" it will break functions into instruction symbols.
Ctheo::decomp::symbol_t	symbol_t is an abstraction upon the coff symbol. this allows for easier manipulation of the symbol. symbols can be different things, sections, functions, and even instructions (when functions are broken down)
Ctheo::recomp::symbol_table_t	this class is a high level wrapper for a hashmap that contains decomp::symbol_t values. the symbol values are references by a hashcode.
Ctheo::theo_t	the main class which encapsulates a symbol table, decomp, and recomp objects. This class is a bridge that connects all three: decomp, obf, recomp
