Class SexpObjectReader

java.lang.Object
  danbikel.parser.SexpObjectReader

All Implemented Interfaces:

ObjectReader

public class SexpObjectReader
extends Object
implements ObjectReader

Reads an underlying stream with a SexpTokenizer, reading each S-expression as a object and returning it when readObject() is invoked.

Constructor Summary

SexpObjectReader(InputStream in)
Constructs a new instance, reading S-expressions from the specified input stream using the default character encoding.

SexpObjectReader(InputStream in, String encoding, int bufSize)
Constructs a new object reader from the specified filename, file encoding and buffer size, by building a SexpTokenizer from the specified arguments.

SexpObjectReader(String filename, String encoding, int bufSize)
Constructs a new object reader from the specified filename, file encoding and buffer size, by building a SexpTokenizer from the specified arguments.

Method Summary

void	close() Closes the underlying stream for this reader.
Object	readObject() Reads the next S-expression from the underlying S-expression reader.
