构造器详细资料

FastLzFrameDecoder

public FastLzFrameDecoder()

Creates the fastest FastLZ decoder without checksum calculation.

FastLzFrameDecoder

public FastLzFrameDecoder(boolean validateChecksums)

Creates a FastLZ decoder with calculation of checksums as specified.

参数:

validateChecksums - If true, the checksum field will be validated against the actual uncompressed data, and if the checksums do not match, a suitable DecompressionException will be thrown. Note, that in this case decoder will use Adler32 as a default checksum calculator.

FastLzFrameDecoder

public FastLzFrameDecoder(java.util.zip.Checksum checksum)

Creates a FastLZ decoder with specified checksum calculator.

参数:

checksum - the Checksum instance to use to check data for integrity. You may set null if you do not want to validate checksum of each block.

方法详细资料

decode

protected void decode(ChannelHandlerContext ctx,
                      ByteBuf in,
                      java.util.List<java.lang.Object> out)
               throws java.lang.Exception

从类复制的说明: ByteToMessageDecoder

Decode the from one ByteBuf to an other. This method will be called till either the input ByteBuf has nothing to read when return from this method or till nothing was read from the input ByteBuf.

指定者:

decode 在类中 ByteToMessageDecoder

参数:

ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to

in - the ByteBuf from which to read data

out - the List to which decoded messages should be added

抛出:

java.lang.Exception - is thrown if an error occurs
