All Implemented Interfaces:

Closeable, Readable

public class Deserializer
extends FilterReader

FilterInputStream subclass that can deserialize Maps, Lists, arrays, and Strings from an ASCII stream. The serialization format is very similar to the output of Map's and List's toString() methods, except strings with non-alphanumeric characters are quoted and special characters are escaped so that the output can be unambiguously deserialized.

Constructor Detail

Deserializer

public Deserializer(Reader reader)

Constructs a Deserializer that takes its input from reader.

Method Detail

readObject

public static Object readObject(Reader reader)

Convenience method for creating a Deserializer taking its input from reader. This method only returns null on error instead of throwing an exception.

useOrderedHashtable

public boolean useOrderedHashtable()

setUseOrderedHashtable

public void setUseOrderedHashtable(boolean useOrderedHashtable)

deserializeObject

public static Object deserializeObject(String serialization)

Convenience method for deserializing from the string serialization. Returns null on error.

readObject

public Object readObject()
                  throws IOException,
                         DeserializationException

Deserializes the next Dictionary, array, List, or String from the current reader.

Throws:

IOException

DeserializationException

readObject

public void readObject(Object instance)
                throws IOException,
                       DeserializationException

Deserializes the next object from the current reader. The result goes *into* the passed in object as opposed to creating a brand new instance. NOTE: Currently, this is only wired up for hashtables. See readObjectInternal(Object instance) for the actual implementation.

Throws:

IOException

DeserializationException
