This sample uses a
String representation of
a serialized
ReportClientDocument object.
You can obtain this value by using the
writeExternal
method of the
ReportClientDocument class and
converting the result to a
String object.
You can use the
readExternal
method of the
ReportClientDocument class to
recreate a
ReportClientDocument object
from its serialized representation.
Convert the
String object to a
byte array.
byte[] bytes = serializedRCD.getBytes();
Create a
ByteArrayInputStream
that contains the byte array, and then create an
ObjectInputStream
object that contains the
ByteArrayInputStream
object.
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes);
ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream);
Create a new
ReportClientDocument object,
and then call the
readExternal
method to recreate the
ReportClientDocument object
from its serialized representation.
ReportClientDocument rcd = new ReportClientDocument();
rcd.readExternal(objectInputStream);
Close the input streams.
objectInputStream.close();
byteArrayInputStream.close();
Example:
This sample creates a
ReportClientDocument object
from a
String representation of
its serialized form.
public ReportClientDocument deserializeReport(String serializedRCD) throws IOException, UnsupportedEncodingException, ClassNotFoundException
{
byte[] bytes = serializedRCD.getBytes();
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes);
ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream);
ReportClientDocument rcd = new ReportClientDocument();
rcd.readExternal(objectInputStream);
objectInputStream.close();
byteArrayInputStream.close();
return rcd;
