This directory contains samples for Dynalink API (http://openjdk.java.net/jeps/276).

These samples require a jar file to be built and such jars be placed in the

classpath of the jjs tool. Linker samples are named with the naming pattern

"xyz_linker.js". These scripts build dynalink linker jar from java code and exec

another jjs process with appropriate classpath set.

Note: you need to build jdk9 forest and put "images/jdk/bin" in your PATH to use

these scripts. This is because these scripts use javac to build dynalink jar and

exec another jjs with classpath set! Alternatively, you can also manually build

dynalink linker jars and invoke sample scripts by putting linker jar in jjs tool's

classpath as well.

Dynalink samples:

* array_stream_linker.js

This sample builds ArrayStreamLinkerExporter.java and uses it in a sample script

called "array_stream.js". This linker adds "stream" property to Java array

objects. The "stream" property returns appropriate Stream type for the given

Java array (IntStream, DoubleStream ...).

* buffer_indexing_linker.js

This sample builds BufferIndexingLinkerExporter.java and uses it in a sample script

called "buffer_index.js". This linker adds array-like indexed access, indexed assignment

and "length" property to Java NIO Buffer objects. Script can treat NIO Buffer objects

as if those are just array objects.

* dom_linker.js

This sample builds DOMLinkerExporter.java and uses it in a sample script

called "dom_linker_gutenberg.js". This linker handles DOM Element objects to add

properties to access child elements of a given element by child element tag name.

This simplifies script access of parsed XML DOM Documents.

* missing_method_linker.js

This sample builds MissingMethodLinkerExporter.java and uses it in a sample script

called "missing_method.js". This linker supports Smalltalk-style "doesNotUnderstand"

calls on Java objects. i.e., A Java class can implement MissingMethodHandler interface

with one method named "doesNotUnderstand". When script accesses a method on such

object and if that method does not exist in the Java class (or any of it's supertypes),

then "doesNotUnderstand" method is invoked.

* underscore_linker.js

This sample builds UnderscoreNameLinkerExporter.java and uses it in a sample script

called "underscore.js". This linker converts underscore separated names to Camel Case

names (as used in Java APIs). You can call Java APIs using Ruby-like naming convention

and this linker converts method names to CamelCase!
