write
@Deprecated(forRemoval=true, since="1.4") public abstract void write(ObjectOutput out) throws IOException Deprecated, for removal: This API element is subject to removal in a future version.This method does not write the values contained by thisPutFieldobject in a proper format, and may result in corruption of the serialization stream. The correct way to writePutFielddata is by calling theObjectOutputStream.writeFields()method.Write the data and fields to the specified ObjectOutput stream, which must be the same stream that produced thisPutFieldobject.- 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 thisPutFieldobject
