Please note: the JSX project has since been developed much more than Hammer (as at 7 July 2002)
Download
Download Hammer.jar - you may need to right-click
and select "Save Link As...".
Extract with jar xfv Hammer.jar
You'll also need JAXP1.1 in your classpath.
Examples (using Vertex.java)
Hammer style XML:
java -classpath Hammer.jar Vertex
Like JSX,
but instead of primitives being attributes, they get their own tag. Thus, every
value - object or primitive - is represented by a tag.
Tags are named after
the type of the value they hold - a DTD-like approach to typing of
JSX.
SOAP style XML:
java -classpath Hammer.jar Vertex soapstyle
SOAP/XML Schema encoding -
an exploratory, rather than a serious implementation. How human readable is
this XML format?
Tags are named for the fieldname that they
hold. Exceptions are the root and array components, which have no fieldname!
Types are omitted where they are the same as the
static type of the field. For instance, In the example file, the first
"left" field is implied to be "Vertex".
Licencing
Hammer is open source (in the downloaded jar), and released under the GPL
(General Public Licence).
This means that any application using Hammer must also be GPL.
Commercial licencing is possible.
