Interface w3c.tools.sexpr.SExprStream

public interface SExprStream
extends SExprParser
An interface for a full s-expression parser.

Method Index

o addParser(char, SExprParser)
Associate an input character with a "sub-parser."
o getListsAsVectors()
Checks whether lists are to be parsed as Vectors or Cons cells.
o getReadtable()
Access the dispatch table of the parser.
o getScratchBuffer()
Accesses an empty string buffer available temporary storage.
o getSymbols()
Access the symbol table of the parser.
o parse()
Parse a single object from the stream.
o read()
Read a single character from the stream.
o readSkipWhite()
Reads from the stream, skipping whitespace.
o setListsAsVectors(boolean)
Controls whether parsed lists are Vectors or Cons cells.
o setReadtable(Readtable)
Assign the dispatch table of the parser.
o setSymbols(Dictionary)
Assign the symbol table of the parser.

Methods

o parse 
 public abstract Object parse() throws SExprParserException, IOException
Parse a single object from the stream.

Throws: SExpParseException
if the input stream cannot be parsed.
Throws: IOException
if the input stream cannot be opened or read.
o getSymbols 
 public abstract Dictionary getSymbols()
Access the symbol table of the parser.

o setSymbols 
 public abstract Dictionary setSymbols(Dictionary symbols)
Assign the symbol table of the parser.

o getReadtable 
 public abstract Readtable getReadtable()
Access the dispatch table of the parser.

o setReadtable 
 public abstract Readtable setReadtable(Readtable readtable)
Assign the dispatch table of the parser.

o addParser 
 public abstract SExprParser addParser(char key,
                                       SExprParser parser)
Associate an input character with a "sub-parser."

o getListsAsVectors 
 public abstract boolean getListsAsVectors()
Checks whether lists are to be parsed as Vectors or Cons cells.

o setListsAsVectors 
 public abstract boolean setListsAsVectors(boolean listsAsVectors)
Controls whether parsed lists are Vectors or Cons cells.

o getScratchBuffer 
 public abstract StringBuffer getScratchBuffer()
Accesses an empty string buffer available temporary storage.

o readSkipWhite 
 public abstract char readSkipWhite() throws IOException
Reads from the stream, skipping whitespace.

o read 
 public abstract int read()
Read a single character from the stream. This method is here because there is no InputStream interface in the java.io package (JavaSoft please take notice!).
