Field Detail

Lambda

protected Object Lambda

serializedLambda

protected com.user00.thunk.SerializedLambda serializedLambda

numCapturedArgs

protected int numCapturedArgs

numLambdaArgs

protected int numLambdaArgs

lambdaIndex

protected int lambdaIndex

JPAQueryComposer stores the lambdas that are chained together to create a query in a list. The lambdaIndex refers to the index of this lambda in the list of lambdas used to create the resulting query.
