Method Detail

close

public void close()

Description copied from interface: Decompressor

Close this decompressor, cleaning up any associated resources. This method is idempotent.

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface Decompressor

status

public Decompressor.Status status()
                           throws DecompressionException

Description copied from interface: Decompressor

Get the current status. Like the other operations on this class, calling this method is not permitted if the decompressor has failed or was closed.

Returns:

The current status

Throws:

DecompressionException

endOfInput

public void endOfInput()
                throws DecompressionException

Description copied from interface: Decompressor

Notify the decompressor that the end of input has been reached. Some implementations may flush remaining data or throw an exception if the input is truncated, but most implementations do nothing. Only permitted for Decompressor.Status.NEED_INPUT.

Throws:

DecompressionException

builder

@UnstableApi
public static SnappyFrameDecompressor.Builder builder()

addInput

public final void addInput(ByteBuf buf)
                    throws DecompressionException

Description copied from interface: Decompressor

Add a new input buffer. Only permitted for Decompressor.Status.NEED_INPUT.

Specified by:

addInput in interface Decompressor

Parameters:

buf - The input buffer. Buffer ownership transfers to the decompressor (also on exception).

Throws:

DecompressionException

takeOutput

public final ByteBuf takeOutput()
                         throws DecompressionException

Description copied from interface: Decompressor

Take a decompressed buffer from this decompressor. Only permitted for Decompressor.Status.NEED_OUTPUT. Buffer ownership transfers to the caller.

Specified by:

takeOutput in interface Decompressor

Returns:

The decompressed buffer. May be empty.

Throws:

DecompressionException
