How can i find if an Path.Element is a Node or a Property?

[Mihai Vasilache]

in my custom org.apache.jackrabbit.core.security.AccessManager i receive a 
org.apache.jackrabbit.spi.Path that may or may not yet exist.

The question is. Can i found that the last element from Node.getElements() is a 
Property or a Node?

Thank you,
Mihai
