ByteBuf	allocate(ByteBufAllocator alloc) Creates a new receive buffer whose capacity is probably large enough to read all inbound data and small enough not to waste its space.

protected RecvByteBufAllocator.Handle	delegate() Get the RecvByteBufAllocator.Handle which all methods will be delegated to.

void	lastBytesRead(int bytes) Set the bytes that have been read for the last read operation.

构造器详细资料

DelegatingHandle

public DelegatingHandle(RecvByteBufAllocator.Handle delegate)

方法详细资料

delegate

protected final RecvByteBufAllocator.Handle delegate()

Get the RecvByteBufAllocator.Handle which all methods will be delegated to.

返回:

the RecvByteBufAllocator.Handle which all methods will be delegated to.

allocate

public ByteBuf allocate(ByteBufAllocator alloc)

从接口复制的说明: RecvByteBufAllocator.Handle

Creates a new receive buffer whose capacity is probably large enough to read all inbound data and small enough not to waste its space.

指定者:

allocate 在接口中 RecvByteBufAllocator.Handle

guess

public int guess()

从接口复制的说明: RecvByteBufAllocator.Handle

Similar to RecvByteBufAllocator.Handle.allocate(ByteBufAllocator) except that it does not allocate anything but just tells the capacity.

指定者:

guess 在接口中 RecvByteBufAllocator.Handle

reset

public void reset(ChannelConfig config)

从接口复制的说明: RecvByteBufAllocator.Handle

Reset any counters that have accumulated and recommend how many messages/bytes should be read for the next read loop.

This may be used by RecvByteBufAllocator.Handle.continueReading() to determine if the read operation should complete.

This is only ever a hint and may be ignored by the implementation.

指定者:

reset 在接口中 RecvByteBufAllocator.Handle

参数:

config - The channel configuration which may impact this object's behavior.

incMessagesRead

public void incMessagesRead(int numMessages)

从接口复制的说明: RecvByteBufAllocator.Handle

Increment the number of messages that have been read for the current read loop.

指定者:

incMessagesRead 在接口中 RecvByteBufAllocator.Handle

参数:

numMessages - The amount to increment by.

lastBytesRead

public void lastBytesRead(int bytes)

从接口复制的说明: RecvByteBufAllocator.Handle

Set the bytes that have been read for the last read operation. This may be used to increment the number of bytes that have been read.

指定者:

lastBytesRead 在接口中 RecvByteBufAllocator.Handle

参数:

bytes - The number of bytes from the previous read operation. This may be negative if an read error occurs. If a negative value is seen it is expected to be return on the next call to RecvByteBufAllocator.Handle.lastBytesRead(). A negative value will signal a termination condition enforced externally to this class and is not required to be enforced in RecvByteBufAllocator.Handle.continueReading().

lastBytesRead

public int lastBytesRead()

从接口复制的说明: RecvByteBufAllocator.Handle

Get the amount of bytes for the previous read operation.

指定者:

lastBytesRead 在接口中 RecvByteBufAllocator.Handle

返回:

The amount of bytes for the previous read operation.

continueReading

public boolean continueReading()

从接口复制的说明: RecvByteBufAllocator.Handle

Determine if the current read loop should continue.

指定者:

continueReading 在接口中 RecvByteBufAllocator.Handle

返回:

true if the read loop should continue reading. false if the read loop is complete.

attemptedBytesRead

public int attemptedBytesRead()

从接口复制的说明: RecvByteBufAllocator.Handle

Get how many bytes the read operation will (or did) attempt to read.

指定者:

attemptedBytesRead 在接口中 RecvByteBufAllocator.Handle

返回:

How many bytes the read operation will (or did) attempt to read.

attemptedBytesRead

public void attemptedBytesRead(int bytes)

从接口复制的说明: RecvByteBufAllocator.Handle

Set how many bytes the read operation will (or did) attempt to read.

指定者:

attemptedBytesRead 在接口中 RecvByteBufAllocator.Handle

参数:

bytes - How many bytes the read operation will (or did) attempt to read.

readComplete

public void readComplete()

从接口复制的说明: RecvByteBufAllocator.Handle

The read has completed.

指定者:

readComplete 在接口中 RecvByteBufAllocator.Handle
