Class NList

All Implemented Interfaces:

public class NList extends Object implements StructConverter
Represents an nlist and nlist_64 structure.

    • initString

      public void initString(BinaryReader reader, long stringTableOffset)
      Initialize the string from the string table.

      You MUST call this method after the NLIST element is created!

      Reading a large NList table can cause a large performance issue if the strings are initialized as the NList entry is created. The string table indexes are scattered. Initializing the strings linearly from the string table is much faster.

      Parameters:
      reader - The BinaryReader
      stringTableOffset - offset of the string table

    • toDataType

      public DataType toDataType() throws DuplicateNameException, 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.

      Specified by:
      toDataType in interface StructConverter
      Returns:
      returns a structure datatype representing the implementor of this interface
      Throws:
      DuplicateNameException - when a datatype of the same name already exists
      IOException - if an IO-related error occurs
