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!
