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