[DBC] Java class file

[danielrhodea]

Hi, I'm new here and I wanted to contribute something, this is the basis of a java class I'm writing to read .dbc files from the filesystem, so far im quite sure it returns true values of string size, record size, field size and record count, I have only verified this using taliis to read the .dbc files, anyway I'm planning to contribute alt more but here it is for now

import java.io.*;
import java.lang.String;
import java.lang.Integer;

public class DBCFile
{
	public DBCFile(String _filename)
	{
		File f = new File(_filename);
		if(f.canRead())
			filename = _filename;
		else
			error = true;
	}

	// Open database. It must be openened before it can be used.
	public void open()
	{
		try
		{
			FileReader f = new FileReader(filename);
			char[] hdr = new char[4];
			
			char[] na = new char[4];
			char[] nb = new char[4];
			char[] es = new char[4];
			char[] ss = new char[4];

			f.read(hdr); // Number of records
			
			assert(String.copyValueOf(hdr) == "WDBC");
			header = String.copyValueOf(hdr);
			f.read(na); // Number of record
			recordCount = (na[0]) | (na[1]) | (na[2]) | (na[3]);
			f.read(nb); // Number of fields
			fieldCount = (nb[0]) | (nb[1]) | (nb[2]) | (nb[3]);
			f.read(es); // Size of a record
			recordSize = (es[0]) | (es[1]) | (es[2]) | (es[3]);
			f.read(ss); // String size
			stringSize = (ss[0]) | (ss[1]) | (ss[2]) | (ss[3]);
			       
			assert(fieldCount *4 == recordSize);
			
			
			data = new char[recordSize * recordCount + stringSize];
			
			stringTable = new char[(data.length) + recordSize * recordCount];
       		
			f.read(data);
       		/*
			String tmp = "";
			for(int i=1*recordSize+stringSize;i<stringSize;i++)
				tmp += String.valueOf(data[i]);
			System.out.println(tmp);
			*/
			f.close();
		}
		catch(IOException exc)
		{
			System.out.println("IOException"+exc.getMessage());
		}
		trace();// uncomment to hide debug info
	}
	private Boolean error = false;
	public Boolean hasError(){
		return error;
	}
	public void trace()
	{
		System.out.println("Traced output... header:"+header+" record count:"+recordCount+" field count:"+fieldCount+" record size:"+recordSize+" string size:"+stringSize+" error:"+hasError());
	}
	private String header;
	private String filename;
	private int recordSize;
	private int recordCount;
	private int fieldCount;
	private int stringSize;
    private char[] data;
    private char stringTable[];
