H5Store

object H5Store

Implements (thread-safe) HDF5 I/O functionality for Series and Frames.

We serialize all reads and writes to the underlying library as recommended here:

http://www.hdfgroup.org/hdf-java-html/JNI/ -- Following the JNI specification, the recommended procedure is to use Java synchronization to create a monitor to serialize access to the library."
