obj = unserialize_pb(con)
close(con)
return (obj)
}
The Java side of operations
Reading an RExp message:
public RExp readRExp() throws IOException {
InputStream is = new FileInputStream("rexp.pb");
try {
CodedInputStream cis = CodedInputStream.newInstance(is);
RExp obj = RExp.parseFrom(cis);
return obj;
} finally {
is.close();
}
}
Writing an RExp message:
public void writeRExp(RExp obj) throws IOException {
OutputStream os = new FileOutputStream("rexp.pb");
try {
CodedOutputStream cos = CodedOutputStream.newInstance(os);
obj.writeTo(cos);
} finally {
os.close();
}
}
