toDataType
Description copied from interface:StructConverter
Returns a structure datatype representing the contents of the implementor of this interface.For example, given:
class A { int foo; double bar; }
The return value should be a structure data type with two data type components; an INT and a DOUBLE. The structure should contain field names and, if possible, field comments.
- Specified by:
toDataType
in interfaceStructConverter
- Overrides:
toDataType
in classDyldCacheSlideInfoCommon
- Returns:
- returns a structure datatype representing the implementor of this interface
- Throws:
DuplicateNameException
- when a datatype of the same name already existsIOException
- if an IO-related error occurs- See Also:
