Method Detail

channelCfg

public ChronicleChannelCfg channelCfg()

Description copied from interface: ChronicleChannel

Retrieves the configuration of the channel.

Specified by:

channelCfg in interface ChronicleChannel

Returns:

the ChronicleChannelCfg instance representing the channel configuration

headerOut

public ChannelHeader headerOut()

Description copied from interface: ChronicleChannel

Retrieves the header for outgoing messages.

Specified by:

headerOut in interface ChronicleChannel

Specified by:

headerIn in interface ChronicleChannel

Returns:

the ChannelHeader instance representing the header for incoming messages

headerInToUse

public ChannelHeader headerInToUse()

Description copied from interface: InternalChronicleChannel

Returns the ChannelHeader to be used for incoming data. The header is determined based on the acceptor's replacement rules.

Specified by:

headerInToUse in interface InternalChronicleChannel

Returns:

the ChannelHeader for incoming data.

testMessage

public void testMessage(long now)

Description copied from interface: ChronicleChannel

Sends a test message using a monotonically increasing timestamp, enabling the caller to wait for a response via lastTestMessage().

Specified by:

testMessage in interface ChronicleChannel

Parameters:

now - a monotonically increasing timestamp

lastTestMessage

public long lastTestMessage()

Description copied from interface: ChronicleChannel

Retrieves the highest timestamp received from the test messages.

Specified by:

lastTestMessage in interface ChronicleChannel

Returns:

the highest timestamp received as a long

close

public void close()

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

isClosed

public boolean isClosed()

Specified by:

isClosed in interface net.openhft.chronicle.core.io.QueryCloseable

readingDocument

public DocumentContext readingDocument()

Specified by:

readingDocument in interface MarshallableIn

writingDocument

public DocumentContext writingDocument(boolean metaData)
                                throws UnrecoverableTimeoutException

Description copied from interface: MarshallableOut

Start a new DocumentContext, must always call close() when done.

Specified by:

Throws:

UnrecoverableTimeoutException

acquireWritingDocument

public DocumentContext acquireWritingDocument(boolean metaData)
                                       throws UnrecoverableTimeoutException

Description copied from interface: MarshallableOut

Start or reuse an existing a DocumentContext, optionally call close() when done.

Specified by:

acquireWritingDocument in interface DocumentWritten

Specified by:

acquireWritingDocument in interface MarshallableOut

Throws:

UnrecoverableTimeoutException

supportsEventPoller

public boolean supportsEventPoller()

Description copied from interface: InternalChronicleChannel

Determines if the current channel supports the EventPoller mechanism for polling events.

Specified by:

supportsEventPoller in interface InternalChronicleChannel

Returns:

true if event pollers are supported by this channel, false otherwise.

eventPoller

public EventPoller eventPoller()

Description copied from interface: InternalChronicleChannel

Retrieves the EventPoller instance associated with this channel. This EventPoller can be used to poll events from the channel.

Specified by:

eventPoller in interface InternalChronicleChannel

Returns:

the EventPoller instance associated with this channel.

eventPoller

public ChronicleChannel eventPoller(EventPoller eventPoller)

Description copied from interface: InternalChronicleChannel

Associates a given EventPoller instance with this channel. This EventPoller will be included in any background processing associated with the channel.

Specified by:

eventPoller in interface InternalChronicleChannel

Parameters:

eventPoller - the EventPoller instance to associate with this channel.

Returns:

this channel instance, allowing for method chaining.

acquireProducer

public WireOut acquireProducer()

Specified by:

acquireProducer in interface InternalChronicleChannel

Returns:

the producer instance as a WireOut object.

releaseProducer

public void releaseProducer()

Description copied from interface: InternalChronicleChannel

Releases the producer instance previously acquired with acquireProducer(). This method should be called when the producer instance is no longer needed, to free up resources.

Specified by:

releaseProducer in interface InternalChronicleChannel

bufferSize

public int bufferSize()

Description copied from interface: InternalChronicleChannel

Returns the size of the buffer used by this channel. The buffer size can impact the performance of the channel, with larger buffers typically providing better throughput at the cost of increased memory usage.

Specified by:

bufferSize in interface InternalChronicleChannel

Returns:

the size of the buffer used by this channel, in bytes.

recordHistory

public boolean recordHistory()

Specified by:

recordHistory in interface MarshallableOut

Returns:
