方法详细资料

encode

public io.netty.buffer.ByteBuf encode(io.netty.buffer.ByteBuf source)

从接口复制的说明: CompressionCodec

Compress a buffer.

指定者:

encode 在接口中 CompressionCodec

参数:

source - a buffer with the uncompressed content. The reader/writer indexes will not be modified

返回:

a new buffer with the compressed content. The buffer needs to be released by the receiver

decode

public io.netty.buffer.ByteBuf decode(io.netty.buffer.ByteBuf encoded,
 int uncompressedLength)
                               throws IOException

从接口复制的说明: CompressionCodec

Decompress a buffer.

The buffer needs to have been compressed with the matching Encoder.

指定者:

decode 在接口中 CompressionCodec

参数:

encoded - the compressed content

uncompressedLength - the size of the original content

返回:

a ByteBuf with the compressed content. The buffer needs to be released by the receiver

抛出:

IOException - if the decompression fails
