Overview (Java Expression Trees library 2.0.0 API)

Packages
Package	Description
com.trigersoft.jaque	Classes to support functional-style operations on streams of remote elements (rows in SQL table, mapped with JPA), such as map-reduce transformations on collections.
com.trigersoft.jaque.expression	Contains classes, interfaces and enumerations that enable language-level code expressions to be represented as objects in the form of expression trees.
com.trigersoft.jaque.function	Contains classes, interfaces and enumerations for static factory methods to create composed functions.
com.trigersoft.jaque.function.math	Contains set of math functors.

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.
