Examples of LambdaInfo

org.jinq.jooq.transform.LambdaInfo
Holds a lambda as well as any additional information about it needed to generate a query from it.
org.jinq.jpa.transform.LambdaInfo
Holds surface information about a lambda such as the parameters to the lambda, the name of the method where the lambda comes from, etc.
