Examples of NetworkElement

com.cloud.network.element.NetworkElement
Represents one network element that exists in a network.
org.jboss.cache.aop.test.NetworkElement
Can represent both software or devices (e.g., sensor).
This object is used to illustrate the pojo cache capability of PojoCache. Note the absence of Serializable interface.
