public interface SExprStream
extends SExprParser

An interface for a full s-expression parser.

Method Summary

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

parse

Method Detail

parse

java.lang.Object parse()
                       throws SExprParserException,
                              java.io.IOException

Parse a single object from the stream.

Throws:

SExprParserException

java.io.IOException

getSymbols

java.util.Dictionary getSymbols()

Access the symbol table of the parser.

setSymbols

java.util.Dictionary setSymbols(java.util.Dictionary symbols)

Assign the symbol table of the parser.

getReadtable

Readtable getReadtable()

Access the dispatch table of the parser.

setReadtable

Readtable setReadtable(Readtable readtable)

Assign the dispatch table of the parser.

addParser

SExprParser addParser(char key,
                      SExprParser parser)

Associate an input character with a "sub-parser."

getListsAsVectors

boolean getListsAsVectors()

Checks whether lists are to be parsed as Vectors or Cons cells.

setListsAsVectors

boolean setListsAsVectors(boolean listsAsVectors)

Controls whether parsed lists are Vectors or Cons cells.

getScratchBuffer

java.lang.StringBuffer getScratchBuffer()

Accesses an empty string buffer available temporary storage.

readSkipWhite

char readSkipWhite()
                   throws java.io.IOException

Reads from the stream, skipping whitespace.

Throws:

java.io.IOException

read

int read()
         throws java.io.IOException

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!).

Throws:

java.io.IOException
