Python¶

Bases: object

This class is the main interface to inspect Objective-C metadata

It can be instantiated using the function lief.MachO.Binary.objc_metadata

property classes → Iterator[lief.objc.Class | None]¶

Return an iterator over the different Objective-C classes (@interface).

get_class(self, name: str) → lief.objc.Class | None¶

Try to find the Objective-C class with the given mangled name.

get_protocol(self, name: str) → lief.objc.Protocol | None¶

Try to find the Objective-C class with the given mangled name.

property protocols → Iterator[lief.objc.Protocol | None]¶

Return an iterator over the Objective-C protocols declared in this binary (@protocol).

to_decl(self, opt: lief.objc.DeclOpt) → str¶

Generate a header-like of all the Objective-C metadata identified in the binary.

The generated output can be configured with the provided DeclOpt parameter.

Bases: object

This class represents an Objective-C class (@interface)

property demangled_name → str¶

Demangled name of the class

property is_meta → bool¶

property ivars → Iterator[lief.objc.IVar | None]¶

Iterator over the different instance variables defined in this class.

property methods → Iterator[lief.objc.Method | None]¶

Iterator over the different methods defined by this class.

property name → str¶

Name of the class

property properties → Iterator[lief.objc.Property | None]¶

Iterator over the properties of this class.

property protocols → Iterator[lief.objc.Protocol | None]¶

Iterator over the different protocols implemented by this class.

property super_class → lief.objc.Class | None¶

Parent class in case of inheritance

to_decl(self, opt: lief.objc.DeclOpt) → str¶

Generate a header-like string for this specific class.

The generated output can be configured with the provided DeclOpt parameter.

Bases: object

This class represents an Objective-C @protocol

property mangled_name → str¶

Mangled name of the protocol

property optional_methods → Iterator[lief.objc.Method | None]¶

Iterator over the methods that could be overridden

property properties → Iterator[lief.objc.Property | None]¶

Iterator over the properties defined in this protocol

property required_methods → Iterator[lief.objc.Method | None]¶

Iterator over the methods of this protocol that must be implemented

to_decl(self, opt: lief.objc.DeclOpt) → str¶

Generate a header-like string for this specific protocol.

The generated output can be configured with the provided DeclOpt parameter.

Bases: object

This class represents an Objective-C Method.

property address → int¶

Virtual address where this method is implemented in the binary

property is_instance → bool¶

Whether it’s an instance method or not.

property mangled_type → str¶

Prototype of the method in its mangled representation (e.g. @16@0:8)

property name → str¶

Name of the method

Bases: object

This class represents an instance variable (ivar)

property mangled_type → str¶

Type of the instance var in its mangled representation (e.g. [29i])

property name → str¶

Name of the instance variable

Bases: object

This class represents a @property in Objective-C

property attribute → str¶

(raw) property’s attributes (e.g. T@"NSString",C,D,N)

property name → str¶

Name of the property

Bases: object

This structure wraps options to tweak the generated output of functions like lief.objc.Metadata.to_decl()

property show_annotations → bool¶

Whether annotations like method’s address should be printed.
