Class GenericFunctionExecutionBuilder<A,L extends AtlanticFunction<A,D>,D extends AtlanticLambda,NEXT extends ExecutionBuilder,RESULT>

java.lang.Object

org.mule.commons.atlantic.execution.builder.ExecutionBuilder<L,RESULT>

org.mule.commons.atlantic.execution.builder.GenericFunctionExecutionBuilder<A,L,D,NEXT,RESULT>

Type Parameters:

A - The type of the first parameter of the AtlanticLambda type that this ExecutionBuilder handles.

L - The AtlanticLambda type that this ExecutionBuilder handles.

NEXT - The type of the ExecutionBuilder that this one downgrades to.

RESULT - The type of result returned by the execution.

public abstract class GenericFunctionExecutionBuilder<A,L extends AtlanticFunction<A,D>,D extends AtlanticLambda,NEXT extends ExecutionBuilder,RESULT>
extends ExecutionBuilder<L,RESULT>

Generic implementation of ExecutionBuilder. Provides the withParam(Object) and withParam(Object, Parser) methods that allow the downgrade of the lambda functions by adding a parameter to them. The withParam(Object) method creates a downgraded instance of the ExecutionBuilder that has an already defined parameter set to it. The withParam(Object, Parser) does the same as the withParam(Object) method but accepts a parser that converts the input before doing so.

Constructor Detail

GenericFunctionExecutionBuilder

protected GenericFunctionExecutionBuilder(L lambda,
                                          List<Object> params,
                                          ExecutionContext<RESULT> context,
                                          TriFunction<D,List<Object>,ExecutionContext,NEXT> nextExecutionBuilderConstructor)

Default constructor.

Parameters:

lambda - The AtlanticLambda to execute.

params - The parameters already accumulated when creating this ExecutionBuilder.

context - The ExecutionContext that contains all the listeners and handlers of the execution.

nextExecutionBuilderConstructor - The constructor of the next ExecutionBuilder. The constructor should match the parameters on ExecutionBuilder.ExecutionBuilder(AtlanticLambda, List, ExecutionContext).

Method Detail

withParam

public NEXT withParam(A param)

Downgrades the ExecutionBuilder to the next level by adding a parameter to it.

Parameters:

param - The parameter that is stored on the context.

Returns:

ExecutionBuilder The next ExecutionBuilder.

withParam

public <INPUT> NEXT withParam(INPUT input,
                              Parser<INPUT,A> parser)

As withParam(Object) but converts the input to the required value of the param using a Parser.

Type Parameters:

INPUT - The type of the unparsed input.

Parameters:

input - The unparsed input.

parser - The Parser that converts from the unparsed input to the required parameter of the execution.

Returns:

ExecutionBuilder The next ExecutionBuilder.
