getMainSection
public int getMainSection()
The mainSection field (4 bytes) specifies the number of the section in this container that contains the main symbol. If the fragment does not have a main symbol, this field is set to -1.- Returns:
- number of section containing main symbol
-
getMainOffset
public int getMainOffset()
The mainOffset field (4 bytes) indicates the offset (in bytes) from the beginning of the section to the main symbol.- Returns:
- offset to the main symbol
-
getInitSection
public int getInitSection()
The initSection field (4 bytes) contains the number of the section containing the initialization function's transition vector. If no initialization function exists, this field is set to -1.- Returns:
- number of the section containing the initialization function's transition vector
-
getInitOffset
public int getInitOffset()
The initOffset field (4 bytes) indicates the offset (in bytes) from the beginning of the section to the initialization function's transition vector.- Returns:
- offset to initialization function's transition vector
-
getTermSection
public int getTermSection()
The termSection field (4 bytes) contains the number of the section containing the termination routine's transition vector. If no termination routine exists, this field is set to -1.- Returns:
- number of the section containing the termination routine's transition vector
-
getTermOffset

toDataType
public DataType toDataType() throws DuplicateNameException, java.io.IOException
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.

in interfaceStructConverter
- Returns:
- returns a structure datatype representing the implementor of this interface
- Throws:
DuplicateNameException
- when a datatype of the same name already existsjava.io.IOException
