Methodendetails

read

public String read()
            throws IOException

read in Schnittstelle ObjectStream<String>

Gibt zurück:

The next object or null to signal that the stream is exhausted.

Löst aus:

IOException - Thrown if there is an error during reading.

reset

public void reset()
           throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Repositions the stream at the beginning and the previously seen object sequence will be repeated exactly. This method can be used to re-read the stream if multiple passes over the objects are required.

The implementation of this method is optional.

Angegeben von:

reset in Schnittstelle ObjectStream<String>

Löst aus:

IOException - Thrown if there is an error during resetting the stream.

close

public void close()
           throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Closes the ObjectStream and releases all allocated resources. After close was called, it's not allowed to call ObjectStream.read() or ObjectStream.reset().

Angegeben von:
