write(ObjectOutput out)
This method was deprecated
in API level 15.
This method does not write the values contained by this
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
public abstract void write (ObjectOutput out)
This method was deprecated
in API level 15.
This method does not write the values contained by this
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 |
ObjectOutput : 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 this PutField
object |
