方法概要

限定符和类型	方法和说明
ByteBuf	allocate(ByteBufAllocator alloc) 已过时。 Creates a new receive buffer whose capacity is probably large enough to read all inbound data and small enough not to waste its space.

方法详细资料

allocate

ByteBuf allocate(ByteBufAllocator alloc)

已过时。

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

guess

int guess()

已过时。

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

reset

void reset(ChannelConfig config)

已过时。

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 continueReading() to determine if the read operation should complete.

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

参数:

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

incMessagesRead

void incMessagesRead(int numMessages)

已过时。

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

参数:

numMessages - The amount to increment by.

lastBytesRead

void lastBytesRead(int bytes)

已过时。

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.

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 lastBytesRead(). A negative value will signal a termination condition enforced externally to this class and is not required to be enforced in continueReading().

lastBytesRead

int lastBytesRead()

已过时。

Get the amount of bytes for the previous read operation.

返回:

The amount of bytes for the previous read operation.

attemptedBytesRead

void attemptedBytesRead(int bytes)

已过时。

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

参数:

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

attemptedBytesRead

int attemptedBytesRead()

已过时。

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

返回:

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

continueReading

boolean continueReading()

已过时。

Determine if the current read loop should continue.

返回:

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

readComplete

void readComplete()

已过时。

The read has completed.
