class angr.knowledge_plugins.cfg.memory_data.MemoryData

Bases: Serializable

MemoryData describes the syntactic content of a single address of memory.

reference_size reflects the size of content. It can be different from size, which is the actual size of the memory data item in memory. The intended way to get the actual content in memory is self.content[:self.size].

__init__(address, size, sort, pointer_addr=None, max_size=None, reference_size=None)

Parameters:

• address (int)

• size (int)

• sort (str | None)

• pointer_addr (int | None)

• max_size (int | None)

• reference_size (int | None)

addr: int

size: int

reference_size: int

sort: str | None

max_size: int | None

pointer_addr: int | None

content: bytes | None

property address

copy()

Make a copy of the MemoryData.

Returns:

A copy of the MemoryData instance.

Return type:

MemoryData

fill_content(loader)

Load data to fill self.content.

Parameters:

loader – The project loader.

Returns:

None
