Constructor Detail

PipedConvertibleNut

public PipedConvertibleNut(Nut o)

Builds a new instance.

Parameters:

o - the transformed nut

PipedConvertibleNut

protected PipedConvertibleNut(String name,
                   NutType ft,
                   Future<Long> v,
                   Boolean comp)

Builds a new instance.

Parameters:

name - the name

ft - the nut type

v - the version

comp - if compressible or not

Method Detail

transform

public static void transform(ConvertibleNut convertibleNut,
             Set<Pipe.Transformer<ConvertibleNut>> transformers,
             List<Pipe.OnReady> callbacks)
                      throws IOException

Apply transformers by chaining each transformer specified in the given list.

Parameters:

convertibleNut - nut to transform

transformers - the transformers chain

callbacks - callbacks to call

Throws:

IOException - if transformation fails

isTransformed

public boolean isTransformed()

Indicates if this nut is transformed or not.

Returns:

true if transformed, false otherwise

transform

public void transform(Pipe.OnReady... onReady)
               throws IOException

Transforms the source stream with all registered transformers and calls the given callback in addition to callbacks previously registered. The method also writes the result to the given output stream.

Parameters:

onReady - the callback

Throws:

IOException - if an I/O error occurs

setTransformed

protected void setTransformed(boolean transformed)

Change the state of this nut by indicating if its transformed or not.

Parameters:

transformed - true if transformed, false otherwise
