Interface WriteAdvHandle

All Superinterfaces:

java.lang.AutoCloseable, ForceableHandle, Handle, ReadHandle

All Known Implementing Classes:

LedgerHandleAdv

@InterfaceAudience.Public
 @InterfaceStability.Unstable
public interface WriteAdvHandle
extends ReadHandle, ForceableHandle

Provide write access to a ledger. Using WriteAdvHandler the writer MUST explictly set an entryId. Beware that the write for a given entryId will be acknowledged if and only if all entries up to entryId - 1 have been acknowledged too (expected from entryId 0)

Since:

4.6

Add entry asynchronously to an open ledger.

Parameters:

entryId - entryId to be added

data - array of bytes to be written do not reuse the buffer, bk-client will release it appropriately.

Returns:

an handle to the result, in case of success it will return the same value of param entryId.
