Parameters:

position - the start of the last written excerpt to this cycle/store

Returns:

this store

writePosition

long writePosition()

Returns:

the start of the last written excerpt to this cycle/store

moveToIndexForRead

@Nullable
@Nullable ScanResult moveToIndexForRead(@NotNull
                                                  @NotNull ExcerptContext ec,
                                                  long index)

moveToStartForRead

@Nullable
@Nullable ScanResult moveToStartForRead(@NotNull
                                                  @NotNull ExcerptContext ec)

sequenceForPosition

long sequenceForPosition(ExcerptContext ec,

                         boolean inclusive)
                  throws StreamCorruptedException

Reverse look up an index for a position.

Parameters:

ec - the wire of the bytes, to work with

position - of the start of the message

Returns:

index in this store.

Throws:

net.openhft.chronicle.wire.UnrecoverableTimeoutException - if the operation times out

StreamCorruptedException

lastSequenceNumber

long lastSequenceNumber(ExcerptContext ec)
                 throws StreamCorruptedException

Throws:

StreamCorruptedException

setPositionForSequenceNumber

                           throws StreamCorruptedException

Sets the position using the provided parameters.

Parameters:

ec - the wire of the bytes, to work with

sequenceNumber - to use when setting position

position - of the start of the message

Throws:

net.openhft.chronicle.wire.UnrecoverableTimeoutException - if the operation times out
