- Subject: how to access elements of java array?
Greetings once more,
This time I have got a problem getting elements of a plain Java
array. I am trying to get elements of a plain java array in
following code:
(let* (
(doc-parts (invoke
(as <org.outerj.daisy.repository.Parts>
(invoke doc 'getParts))
'getArray)))
(log-info (array? doc-parts)) ; says false
(array-ref doc-parts 0) ; throws exception, below
)
Invalid parameter, was: [Lorg.outerj.daisy.repository.Part;
java.lang.ClassCastException: [Lorg.outerj.daisy.repository.Part;
at
gnu.kawa.functions.ArrayRef.applyN(ArrayRef.java:34)
at gnu.mapping.ProcedureN.apply2(ProcedureN.java:39)
at gnu.kawa.functions.ArrayRef.apply2(ArrayRef.java:28)
at atInteractiveLevel$8.dsyCheckout(dsy.scm:58)
at atInteractiveLevel$8.apply0(dsy.scm:40)
the getParts method of the instance referred by doc variable returns
Part[] array.
What is the right way to access, get, set elements of plain java
arrays returned from the Java code?
With best regards,
