Class ChainBuilder<I,O>

java.lang.Object

ca.mcscert.jpipe.compiler.model.ChainBuilder<I,O>

Type Parameters:

I - input type of the chain (type produced by the Source).

O - current output type (changes with each andThen call).

public final class ChainBuilder<I,O>
extends Object

Fluent builder that accumulates Transformations into a compilation chain. Call andThen(Transformation) to append steps; finalise with andThen(Sink) to produce a ChainCompiler.

Method Summary

Modifier and Type	Method	Description
ChainCompiler<I,O>	andThen(Sink<O> sink)	Finalise the chain by attaching a sink, producing a ready-to-use Compiler.
<R> ChainBuilder<I,R>	andThen(Transformation<O,R> next)	Append a transformation to the end of the current chain.
Transformation<I,O>	asTransformation()	Expose the accumulated chain as a plain Transformation, useful when the chain is embedded inside a larger pipeline rather than used standalone.

Method Details

andThen

public <R> ChainBuilder<I,R> andThen(Transformation<O,R> next)

Append a transformation to the end of the current chain.

Type Parameters:

R - new output type.

Parameters:

next - the step to add.

Returns:

a new builder with the extended chain.

andThen

public ChainCompiler<I,O> andThen(Sink<O> sink)

Finalise the chain by attaching a sink, producing a ready-to-use Compiler.

Parameters:

sink - the final serialisation step.

Returns:

a complete ChainCompiler.

asTransformation

public Transformation<I,O> asTransformation()

Expose the accumulated chain as a plain Transformation, useful when the chain is embedded inside a larger pipeline rather than used standalone.

Returns:

the composed transformation.
