Method Detail

get

public static ByteBufPair get(io.netty.buffer.ByteBuf b1,
                              io.netty.buffer.ByteBuf b2)

Get a new ByteBufPair from the pool and assign 2 buffers to it.

The buffers b1 and b2 lifecycles are now managed by the ByteBufPair: when the ByteBufPair is deallocated, b1 and b2 will be released as well.

Parameters:

b1 -

b2 -

Returns:

getFirst

public io.netty.buffer.ByteBuf getFirst()

getSecond

public io.netty.buffer.ByteBuf getSecond()

readableBytes

public int readableBytes()

coalesce

public static io.netty.buffer.ByteBuf coalesce(ByteBufPair pair)

Returns:

a single buffer with the content of both individual buffers

deallocate

protected void deallocate()

Specified by:

deallocate in class io.netty.util.AbstractReferenceCounted

touch

public io.netty.util.ReferenceCounted touch(java.lang.Object hint)
