getNameList

public List<String> getNameList()

isModified

public boolean isModified()

getLastModified

public long getLastModified()

Description copied from interface: IModifyableResource

Return the current last modification time. This must return the ACTUAL modification time of the resource; the time returned by this call will be compared with the time that the resource was last used (stored somewhere else) to decide if this resource has changed in the meantime. This call must return -1 for a resource that does not exist - because non-existence is a valid caching criteria too!
