write
@Deprecated public abstract void write(ObjectOutput out) throws IOException
PutField
object in a proper format, and may result in corruption of the serialization stream. The correct way to write PutField
data is by calling the ObjectOutputStream.writeFields()
method.Write the data and fields to the specified ObjectOutput stream, which must be the same stream that produced this PutField
object.
- Parameters:
-
out
- the stream to write the data and fields to - Throws:
-
IOException
- if I/O errors occur while writing to the underlying stream -
IllegalArgumentException
- if the specified stream is not the same stream that produced thisPutField
object
