Class SpannedSerializator

java.lang.Object

su.whs.watl.experimental.SpannedSerializator

public class SpannedSerializator
extends java.lang.Object

Helper, writes Spanned to DataOutputStream, and reads it's back - from DataInputStream to Spanned to support custom CharacterStyle and ParagrpahStyle - override class and implements own read(int tag, DataInputStream dis) and write(Object o, DataOutputStream dos) write(Object o, DataOutputStream dos) must write int 'tag' (>100), and Span paramteres to stream, and read will be called with 'tag' - and correct instance must be constructed, used prevously written N bytes from stream
