Member Function Documentation

accept()

void LIEF::MachO::Relocation::accept ( Visitor & visitor ) const

overridevirtual

Implements LIEF::Object.

Reimplemented in LIEF::MachO::RelocationDyld, LIEF::MachO::RelocationFixup, and LIEF::MachO::RelocationObject.

architecture()

Header::CPU_TYPE LIEF::MachO::Relocation::architecture ( ) const

inline

Achitecture targeted by this relocation.

clone()

virtual std::unique_ptr< Relocation > LIEF::MachO::Relocation::clone ( ) const

pure virtual

Implemented in LIEF::MachO::RelocationDyld, LIEF::MachO::RelocationFixup, and LIEF::MachO::RelocationObject.

has_section()

bool LIEF::MachO::Relocation::has_section ( ) const

inline

true if the relocation has a section associated with

has_segment()

bool LIEF::MachO::Relocation::has_segment ( ) const

inline

true if the relocation has a SegmentCommand associated with

has_symbol()

bool LIEF::MachO::Relocation::has_symbol ( ) const

inline

true if the relocation has a symbol associated with

is_pc_relative()

virtual bool LIEF::MachO::Relocation::is_pc_relative ( ) const

pure virtual

Indicates whether the item containing the address to be relocated is part of a CPU instruction that uses PC-relative addressing.

For addresses contained in PC-relative instructions, the CPU adds the address of the instruction to the address contained in the instruction.

Implemented in LIEF::MachO::RelocationDyld, LIEF::MachO::RelocationFixup, and LIEF::MachO::RelocationObject.
