Creates a new list from a type string and an array of S-expressions.

Parameters:

type - the list type string

expressions - the elements of the list

Method Detail

getType

public java.lang.String getType()

Returns the type of this list.

size

public int size()

Returns the size of this list.

iterator

public java.util.Iterator iterator()

Returns an iterator over this list. Each element is an Sexp.

isEmpty

public boolean isEmpty()

Returns true if this list is empty, false otherwise.

writeCanonical

public void writeCanonical(java.io.OutputStream out)
                    throws java.io.IOException

Description copied from class: Sexp

Writes this S-expression to a byte stream in canonical form.

Specified by:

writeCanonical in class Sexp

java.io.IOException

writeReadable

public void writeReadable(java.io.Writer out,
                          int offset,
                          int width,
