class angr.storage.memory_object.SimMemoryObject¶

Bases: object

A SimMemoryObject is a reference to a byte or several bytes in a specific object in memory. It should be used only by the bottom layer of memory.

concrete_bytes(offset, size)¶

Return type:

bytes | None

Parameters:

offset (int)
size (int)

class angr.storage.memory_object.SimLabeledMemoryObject¶

Bases: SimMemoryObject

SimLabeledMemoryObject is a SimMemoryObject with a label

angr.storage.memory_object.bv_slice(value, offset, size, rev, bw)¶

Extremely cute utility to pretend you’ve serialized a value to stored bytes, sliced it a la python slicing, and then deserialized those bytes to an integer again.

Parameters:

value (BV) – The bitvector to slice
offset (int) – The byte offset from the first stored byte to slice from, or a negative offset from the end.
size (int) – The number of bytes to return. If None, return all bytes from the offset to the end. If larger than the number of bytes from the offset to the end, return all bytes from the offset to the end.
rev (bool) – Whether the pretend-serialization should be little-endian
bw (int) – The byte width

Return type:

BV

Returns:

The new bitvector
