Lambda expressionsare known to many of us who have worked on other popular programming languages like Scala. In Java programming language, a Lambda expression (or function) is just ananonymous function, i.e., afunction with no nameand without being bound to an identifier. Lambda expressions are...
The Hibernate jar file is 7 MB in size. Hibernate takes time at start-up to inspect annotations and create its ORM capability. This is enormously powerful, but for a Lambda, it can be overkill. As Lambdas are usually written to perform small tasks, the overhead of Hibernate may not be ...
Ensure the IAM user that performs this task in the console has admin permissions for the Lambda service -- i.e., Create, Update, Delete, Get and Invoke operations -- andiam:PassRole. This specifies the execution IAM role users assign to their Lambda function. Step 1. Create function To c...

Once the method body is parsed, we do an initial "binding" pass, where we attempt to determine the types of every expression in every statement. We then do a whole pile of passes over each method body. Again, at this point we are done looking at the source code; we're now passing ...
Jay is an Open Source Compiler-Compiler tool derived from Berkeley Yacc. It is used in the Mono project as a Compiler-Compiler tool to generate the parser of the Mono C# compiler. Jay reads the grammar specification from a grammar file and generates an LR parser for it. Thiscs-parser.jay...
