Interface Stringizable

All Known Implementing Classes:

List, Table, LabeledData, LoggerMessage

public abstract interface Stringizable

An interface for objects that can convert itself to a string and "recreate" itself from that string. This interface is much more limited than Serializable. The few advantages Stringizable has over Serializable are: Stringizable works with Java 1.0.2, the string version of an object is readable and parsable by humans, and the string version of an object is ligher weight than in Serializable. The main use of Stringizable is for use in Java 1.0.2, motivate for students the utility of Serializable with less overhead, and for use in client-server programing where the strings must satisfy a protocol.

Method Detail

fromString

public void fromString(java.lang.String objectString)
                throws ConversionException

Converts a string to an object. String must be created from object of same Class you are trying to recreate.

Throws:

ConversionException - If there is a problem converting to object.

setMetaData

public void setMetaData(LabeledData metaData)
