Method Details [hide private]

__init__(self, archmod=None)
(Constructor)

source code 

Take a set of memory maps (va, perms, fname, bytes) and put them in a sparse space finder. You may specify your own page-size to optimize the search for an architecture.

Overrides: IMemory.__init__

addMemoryMap(self, va, perms, fname, bytes)

source code 

Add a memory map to this object...

Overrides: IMemory.addMemoryMap

getMemorySnap(self)

source code 

Take a memory snapshot which may be restored later.

Example: snap = mem.getMemorySnap()

setMemorySnap(self, snap)

source code 

Restore a previously saved memory snapshot.

Example: mem.setMemorySnap(snap)

getMemoryMap(self, va)

source code 

Get the va,size,perms,fname tuple for this memory map

Overrides: IMemory.getMemoryMap

getMemoryMaps(self)

source code 
Overrides: IMemory.getMemoryMaps

readMemory(self, va, size)

source code 

Read memory from the specified virtual address for size bytes and return it as a python string.

Example: mem.readMemory(0x41414141, 20) -> "A..."

Overrides: IMemory.readMemory
(inherited documentation)

writeMemory(self, va, bytes)

source code 

Write the given bytes to the specified virtual address.

Example: mem.writeMemory(0x41414141, "VISI")

Overrides: IMemory.writeMemory
(inherited documentation)

getByteDef(self, va)

source code 

An optimized routine which returns the existing segment bytes sequence without creating a new string object *AND* an offset of va into the buffer. Used internally for optimized memory handling. Returns (offset, bytes)
