Subject [jira] [Updated] (BEANUTILS-406) DynaClassReader to read DynaClass definitions from a "DSL"
Date Sun, 06 Nov 2011 12:36:51 GMT

     [ https://issues.apache.org/jira/browse/BEANUTILS-406?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael Vorburger updated BEANUTILS-406:
----------------------------------------

    Attachment: 0002-BEANUTILS-406-DynaClassReader-to-read-DynaClass-defi.patch

Attached proposed patch.  This builds on top of the two patches in BEANUTILS-405.

Same also on https://github.com/vorburger/apache-commons-beanutils/commits/domain-file-reader
- would be easier to contribute via BEANUTILS-404 ... ;-)

> It could sometimes be very useful to create DynaClass definitions not only programmatically
(as is possible today), but to define data structures in some textual format (a "DSL"), and
load that into DynaClass/DynaProperty and create DynaBeans from that.
> This isn't very hard to add to BeanUtils (I've done it and will attach a patch) and would
allow the following usage, given:
> {noformat}Address  { 
> 	zip:  java.lang.Long 
> }
> Employee {
>         firstName : java.lang.String
> 	lastName :java.lang.String   
> 	
> 	mainAddress  : Address
> 	boss         : Employee
> 	subordinates : Employee *
> 	address      : Address <>
> }{noformat}
> one could then use the new proposed DynaClassReader like so:
> {noformat}DynaClassReader r = new DynaClassReader();
> r.readClasspathResource("/DynaClassReaderTest.domain.txt");
> DynaClass klass = r.getDynaClass("Employee");
> {noformat}
> This requires BEANUTILS-405.
