All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.Appendable

Direct Known Subclasses:

FormattingSerializer

public class Serializer
extends java.io.FilterWriter

Object subclass that can serialize a fixed set of data types (Dictionaries, arrays, Lists, and Strings) to an ASCII writer. If the object passed in is not one of these types, or contains an object that is not one of these types, the Serializer converts the object to a string via the object's toString() method. The serialization format is very similar to the output of Map's and List's toString() methods, except that strings with non-alphanumeric characters are quoted and special characters are escaped, so that the output can be unambiguously deserialized. Serializer produces an ASCII representation with few, if any, spaces separating components. To get a more readable representation, use the OutputSerializer class.

Note:

1.0 Added several unsafe characters that will always be quoted (fixed problem with archiving the @ symbol)

serializeObject

public static java.lang.String serializeObject(java.lang.Object anObject)

Convenience method for generating anObject's ASCII serialization. Returns null on error.

writeObject
