This library enables language-level code expressions to be represented as objects in the form of expression trees at runtime:


void method(Predicate<Float> p) {
  LambdaExpression<Predicate<Float>> parsed = LambdaExpression.parse(p);
  //Use parsed Expression Tree...
}

making it possible to create type-safe fluent interfaces, i.e. instead of:


Customer obj = ...
obj.property("name").eq("John")

one can write


method<Customer>(obj -> obj.getName() == "John")

in type-safe, refactoring friendly manner.

The jdk.internal.lambda.dumpProxyClasses system property must be set and point to an existing writable directory to give the parser access to the lambda byte code.
