Class ExecutionBuilder<L extends AtlanticLambda,RESULT>

java.lang.Object

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

Type Parameters:

L - The type of AtlanticLambda to handle.

RESULT - The type of result returned by the execution.

Direct Known Subclasses:

FunctionExecutionBuilder, GenericFunctionExecutionBuilder, SupplierExecutionBuilder

public class ExecutionBuilder<L extends AtlanticLambda,RESULT>
extends Object

Parent of all the execution builders. This class provides the basic structure for all the ExecutionBuilders to work. An ExecutionBuilder takes a determined type of AtlanticLambda and works it's way down by adding parameters to it and converting into the next type of ExecutionBuilder that handles the AtlanticLambda with one less parameter. This ends when there are no more parameters and the last ExecutionBuilder, an instance of FunctionExecutionBuilder or SupplierExecutionBuilder, gets the Executor from the ExecutionContext and executes the lambda on it. An example of how ExecutionBuilders work is the following: TriFunctionExecutionBuilder<MyParam1Type, MyParam2Type, MyParam3Type, MyResultType, MyResultType> original = new TriFunctionExecutionBuilder<>(MyClass::staticMethodWith3Params, new ArrayList<>(), Parser.self(), myExecutionContext); FunctionExecutionBuilder<MyParam2Type, MyParam3Type, MyResultType, MyResultType> next = new TriFunctionExecutionBuilder<>(MyClass::staticMethodWith3Params, new ArrayList<>(), Parser.self(), myExecutionContext).withParam(param1); FunctionExecutionBuilder<MyParam3Type, MyResultType, MyResultType> last = next.withParam(param2); MyResultType result = last.withParam(param3); To simplify that block of code, the use is the following: MyResultType result = new TriFunctionExecutionBuilder<>(MyClass::staticMethodWith3Params, new ArrayList<>(), Parser.self(), myExecutionContext).withParam(param1) .withParam(param2) .withParam(param3); This class also contains an ExecutionContext, which will provide functionality over the execution of the lambda.
