public interface Streamable

Implementations of Streamable can add their state directly to the output stream, enabling them to bypass costly serialization

Method Summary

void	readFrom(java.io.DataInput in) Read the state of the current object (including superclasses) from instream Note that the input stream must not be closed
void	writeTo(java.io.DataOutput out) Write the entire state of the current object (including superclasses) to outstream.

Method Detail

writeTo

void writeTo(java.io.DataOutput out)
             throws java.lang.Exception

Write the entire state of the current object (including superclasses) to outstream. Note that the output stream must not be closed

Throws:

java.lang.Exception

readFrom

void readFrom(java.io.DataInput in)
              throws java.lang.Exception

Read the state of the current object (including superclasses) from instream Note that the input stream must not be closed

Throws:

java.lang.Exception
