getBytes
Description copied from interface:IMemorySource
Reads data from the memory range- Specified by:
getBytes
in interfaceIMemorySource
- Parameters:
address
- Starting addressbuffer
- Buffer to read intooffset
- Offset in buffer to write tolength

-
getName
- Specified by:
getName
in interfaceIMemoryRange
- Returns:
- Name of this range (e.g. .text or stack), or null if range is unnamed.
-

- Specified by:
getProperties
in interfaceIDetailedMemoryRange
-
isExecutable
public boolean isExecutable()- Specified by:
isExecutable
in interfaceIMemoryRange
-
isReadOnly
public boolean isReadOnly()Assuming that just because something is executable doesn't stop it being read only. (ReadOnly is not actually a very good property to expose since it relies on the lack of other properties.)- Specified by:
