 # This is an example script designed to show how to use ease with ICE. It 
 # creates a new Reflectivity Model and shows how to customize and build up
 # the layers in the model from scratch. 
 # ****************************************************************************

# Needed imports from ICE
from org.eclipse.ice.datastructures.form import Material

# Load the Platform module for accessing OSGi services
loadModule('/System/Platform')

# Get the core service from ICE for creating and accessing objects. 
coreService = getService(org.eclipse.ice.core.iCore.ICore);

# Create the reflectivity model to be used and get its reference. The create item 
# method will return a string representing the number of that item, so use int() to 
# convert it to an integer. 
reflectModel = coreService.getItem(int(coreService.createItem("Reflectivity Model")))

# Gets the list component used as the data for the table (is on tab 2)
listComp = reflectModel.getComponent(2)

# Now we want to build up the list from our own data, so we can do that here.

# The first step would be to clear the list so that we can start adding to it. Clearing
# the list requires the locks as multiple operations are happening and we need to 
# protect the list from multiple threads trying to access it at the same time. 
listComp.getReadWriteLock().writeLock().lock()
listComp.clear()
listComp.getReadWriteLock().writeLock().unlock()

# Create the layer of air
