Checking Whether a Namespace Exists

Syntax Syntax

  1. private boolean namespaceExists(String myNamespace)
	{
		try
		{
			IPcdContext ucdContext = getUcdContext();
			ucdContext.addToEnvironment(Constants.REQUESTED_ASPECT, IPcdAttribute.ASPECT_EXISTENCE);
			Boolean exists = (Boolean) ucdContext.lookup(myNamespace);
			return exists.booleanValue();
		}
		catch (NamingException e)
		{
			return false;
		}
	}
End of the code.
Getting a Namespace

Syntax Syntax

  1. private INamespace getNamespace(String myNamespace) throws NamingException
	{
		IPcdContext ucdContext = getUcdContext();
		ucdContext.addToEnvironment(Constants.REQUESTED_ASPECT, PcmConstants.ASPECT_SEMANTICS);
		INamespace namespace = (INamespace) ucdContext.lookup(myNamespace);
		return namespace;
	}
End of the code.
Creating a Namespace

Syntax Syntax

  1. private INamespace createNamespace(String myNamespace) throws NamingException
	{
		IPcdContext ucdContext = getUcdContext();
		INamespaceManager namespaceManager = (INamespaceManager) PortalRuntime.getRuntimeResources().getService (INamespaceManager.KEY);
		INamespaceDescriptor myNamespaceDesc = (INamespaceDescriptor) namespaceManager.instantiateDescriptor(myNamespace);
		ucdContext.bind(myNamespace, myNamespaceDesc);
		return getNamespace(myNamespace);
	}
End of the code.
