Detailed Description

This class represents an entry in the exception table (.pdata section) for the AArch64 architecture.

Since the ARM64 unwinding info can be encoded in a packed and unpacked format, this class is inherited by LIEF::PE::unwind_aarch64::PackedFunction and LIEF::PE::unwind_aarch64::UnpackedFunction
