Constructor Detail

SexpOutputStream

public SexpOutputStream(java.io.OutputStream os)

Creates a new SexpOutputStream that writes to the given stream.

Method Detail

writeReadable

public void writeReadable(Sexp s,
                          int offset,
                          int width,
                          int last)
                   throws java.io.IOException

Writes an S-expression to the stream in readable form.

Parameters:

s - the S-expression to write.

offset - spaces indented from left.

width - total width of window, in characters.

last - spaces reserved on right (e.g., for closing parens).

Throws:

java.io.IOException - if there is an IO error.

writeTransport

public void writeTransport(Sexp s)
                    throws java.io.IOException

Writes an S-expression to the stream in transport form.

Parameters:

s - the S-expression to write.

Throws:

java.io.IOException - if there is an IO error.

writeCanonical

public void writeCanonical(Sexp s)
                    throws java.io.IOException

Writes an S-expression to the stream in canonical form.

Parameters:

s - the S-expression to write

Throws:

java.io.IOException - if there is an IO error

toReadable

public SexpOutput toReadable(int offset,
                             int width,
                             int last)

Returns a new SexpOutput object that writes S-expressions to this stream in readable form.

Parameters:

offset - spaces indented from left.

width - total width of window, in characters.

last - spaces reserved on right (e.g., for closing parens).

toCanonical

public SexpOutput toCanonical()

Returns a new SexpOutput object that writes S-expressions to this stream in canonical form.

toTransport

public SexpOutput toTransport()

Returns a new SexpOutput object that writes S-expressions to this stream in transport form.
