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

getProperties
- Specified by:
getPropertiesin interfaceIDetailedMemoryRange
-
isExecutable
public boolean isExecutable()- Specified by:
isExecutablein 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:
