In Java, the @FunctionalInterface annotation is used to indicate that an interface is a functional interface. A functional interface is an interface that has only one abstract method. In other words, it is an i
Thus a single target type will be able to express multiple, possibly unrelated, properties of one \\(\\lambda \\) -expression.We formalise our proposal through a minimal Java core extended with these novel features and we prove the type safety property....

lambda has special semantics for return; this is not supported. Stabby lambda is also not supported. Only simple for iteration variables are supported. Control flow for exceptions is not analyzed fully soundly; some things are not reported as possibly nil that could be. Only simple usage of con...

with Java involves working with type information. In particular, Java's generics do not provide a way to resolve or reify the type information for a given class. TypeTools looks to solve this by fully resolving generic type information declared on any class, interface, lambda expression or ...
To filter on a complex collection field, you can use alambda expressionwith theanyandalloperators. In that case, therange variableof the lambda expression is an object with subfields. You can refer to those subfields with the standard OData path syntax. For example, the following filter returns...
