[gdal-dev] Java API: how to find dimensions of MDArray

[Even Rouault]

Barry,

This method is indeed not available currently in the Java bindings. It 
is only available currently in the Python bindings (see 
https://github.com/OSGeo/gdal/blob/master/swig/include/MultiDimensional.i#L159 
) , since it requires writing a specific SWIG typemap for each binding 
language when a method returns (or takes as argument) a new 
non-primitive type such as here, with an array of dimensions. The 
closest existing Java typemap I found that can be used to take 
inspiration from is 
https://github.com/OSGeo/gdal/blob/master/swig/include/java/typemaps_java.i#L235 
but there would be changes to call the "Dimension(long cPtr, boolean 
cMemoryOwn)" constructor.  Whether you want to try to tackle that 
yourself or not, you may create a ticket about that
