Josiah,
There doesn't seem to be a Java example, but there is a C example:
http://www.hdfgroup.org/ftp/HDF5/examples/examples-by-api/hdf5-examples/1_8/C/H5T/h5ex_t_vlen.c
Also, is there a maximum size for the array of doubles? If so, you may
be better off using a fixed length array and a separate field to store
the actual length, then using compression to mostly eliminate the wasted
space.
Thanks,
-Neil

Thanks. Can you point me to any examples using H5Tvlen_create() in
context (preferably Java, but I'll take what I can get)?
Hmm, I don't see any code that uses H5Tvlen_create() in our
examples files, but you can look at test/tvltypes.c for examples of
how it's used in the context of our regression tests. Perhaps Peter
has a pointer to a Java example...

Hi folks -
I've got another naive question about building Datatypes. I've got
a Datatype that I'm forming from arrays of doubles. Ultimately,
I'll be writing an array of this Datatype. The complicating
factor is that the arrays of doubles won't necessarily have the
same dimensions from one instance of the Datatype to the next.
Sounds like you might want a variable-length sequence of
doubles as your datatype. Look at the documentation for
H5Tvlen_create()...

Here's a little pseudo-code to more concretely illustrate what I
mean:
Datatype {
double[] a;
double[][] b;
double[] c;
};
Datatype[] allData = {
{ a = {1., 2., 3.} } b = {{1.,2.},{3.,4.}}, c = {1.} },
{ a = {1.,} b = {{1.}}, c = {1., 2.} },
{ a = {}, b = {{1.}, {2.}}, c = {1., 2., 3.} }
};
I'm trying to use the Java H5 class to achieve this.
Thanks in advance for your time.
