getSymbolOffset
public int getSymbolOffset()An integer containing the byte offset from the start of the file to the location of the symbol table entries. The symbol table is an array of nlist data structures.- Returns:
- symbol table offset
-
getNumberOfSymbols
public int getNumberOfSymbols()An integer indicating the number of entries in the symbol table.- Returns:
- the number of entries in the symbol table
-
getStringTableOffset
public int getStringTableOffset()An integer containing the byte offset from the start of the image to the location of the string table.- Returns:
- string table offset
-
getStringTableSize
public int getStringTableSize()An integer indicating the size (in bytes) of the string table.- Returns:
- string table size in bytes

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.
- Returns:
- returns a structure datatype representing the implementor of this interface
- Throws:
DuplicateNameException
- when a datatype of the same name already existsIOException
