Konstruktordetails

AbstractEventStream

public AbstractEventStream(ObjectStream<T> samples)

Initializes an AbstractEventStream with a sample Iterator.

Parameter:

samples - The Iterator that provides the AbstractEventStream samples.

Methodendetails

read

public final Event read()
                 throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Returns the next ObjectStream object. Calling this method repeatedly until it returns null will return each object from the underlying source exactly once.

Angegeben von:

read in Schnittstelle ObjectStream<T>

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,
UnsupportedOperationException

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<T>

Löst aus:

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

UnsupportedOperationException - Thrown if the reset() is not supported. By default, this is the case.

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:

close in Schnittstelle AutoCloseable

Angegeben von:

close in Schnittstelle ObjectStream<T>

Löst aus:

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