方法详细资料

isDurable

public boolean isDurable()

从接口复制的说明: ManagedCursor

Tells whether the cursor is durable or just kept in memory.

指定者:

isDurable 在接口中 ManagedCursor

覆盖:

isDurable 在类中 ManagedCursorImpl

internalAsyncMarkDelete

protected void internalAsyncMarkDelete(PositionImpl newPosition,
 Map<String,Long> properties,
 AsyncCallbacks.MarkDeleteCallback callback,
 Object ctx)

覆盖:

internalAsyncMarkDelete 在类中 ManagedCursorImpl

asyncClose

public void asyncClose(AsyncCallbacks.CloseCallback callback,
 Object ctx)

从接口复制的说明: ManagedCursor

Close the cursor asynchronously and release the associated resources.

指定者:

asyncClose 在接口中 ManagedCursor

覆盖:

asyncClose 在类中 ManagedCursorImpl

参数:

callback - callback object

ctx - opaque context

asyncDeleteCursor

public void asyncDeleteCursor(String consumerName,
 AsyncCallbacks.DeleteCursorCallback callback,
 Object ctx)

isReadCompacted

public boolean isReadCompacted()

rewind

public void rewind()

从接口复制的说明: ManagedCursor

Rewind the cursor to the mark deleted position to replay all the already read but not yet mark deleted messages.

The next message to be read is the one after the current mark deleted message.

指定者:

rewind 在接口中 ManagedCursor

覆盖:

rewind 在类中 ManagedCursorImpl

toString

public String toString()

覆盖:

toString 在类中 ManagedCursorImpl
