Detailed Description

Base class to provide methods to describe a type, as well as how to set
and get fields from virtual mem.

Each Type subclass is linked to a MemType subclass (e.g. Struct to
MemStruct, Ptr to MemPtr, etc.).

When nothing is specified, MemValue is used to access the type in memory.
MemValue instances have one `.val` field, setting and getting it call
the set and get of the Type.

Subclasses can either override _pack and _unpack, or get and set if data
serialization requires more work (see Struct implementation for an example).

TODO: move any trace of vm and addr out of these classes?

get()

def miasm.core.types.Type.get	(		self,
			vm,
			addr
	)

Get the python value of a field from a VmMngr memory at @addr.

lval()

def miasm.core.types.Type.lval

(

self

)

Returns a class with a (vm, addr) constructor that allows to
interact with this type in memory.

In compilation terms, it returns a class allowing to instantiate an
lvalue of this type.

@return: a MemType subclass.

Here is the caller graph for this function:

set()

def miasm.core.types.Type.set	(		self,
			vm,
			addr,
			val
	)

Set a VmMngr memory from a value.

@vm: VmMngr instance
@addr: the start address in memory to set
@val: the python value to serialize in @vm at @addr

Reimplemented in miasm.core.types.BitField, miasm.core.types.Bits, miasm.core.types.Array, miasm.core.types.Struct, miasm.core.types.Ptr, and miasm.core.types.Str.

size()

def miasm.core.types.Type.size

(

self

)

Return the size in bytes of the serialized version of this field

Reimplemented in miasm.core.types.Str, miasm.core.types.Bits, miasm.core.types.Array, miasm.core.types.Union, miasm.core.types.Struct, and miasm.core.types.RawStruct.
