# HashMap Key-Value pairs
HashMap = snappy.jpy.get_type('java.util.HashMap')

master_prod = ProductIO.readProduct("/home/user/../terr_20181020T225310.dim")
slave_prod = ProductIO.readProduct("/home/user/../terr_20181121T111129.dim")

# set products
sourceProducts = HashMap()
sourceProducts.put('masterProduct', master_prod)
sourceProducts.put('slaveProduct', slave_prod)

parameters = HashMap()
