LuciadLightspeedInterface ILfnReadCallback

All Superinterfaces:

ILfnCallback<ALfnTileStore.ReadResult>

public interface ILfnReadCallback
extends ILfnCallback<ALfnTileStore.ReadResult>

An extension of the general ILfnCallback which adds a specific callback for when content is found. When content is found, it marks a non-final state in the read operation's life cycle: writing to the receiver's channel has yet to commence. When all content is written, a final call to ILfnCallback.completed(Object) will be made.

This callback replaces ILfnGetTileHandler.

Since:

2013.1

Method Detail

found

void found(long aContentLength,
           long aModificationTime)

A non-final callback made right before content will be written to the receiver's channel. It allows implementers to for example allocate a buffer of the exact content length. Bear in mind that the modification time may be truncated to second precision because of file system limitations.

Parameters:

aContentLength - the content length in bytes

aModificationTime - the modification time in milliseconds since epoch
