Method Summary
`void`	`addFlow(Flow flow)` Adds the given flow to this view.
`void`	`addHost(Host host)` Adds the given host to this view.
`void`	`addLayer(Layer layer)` Adds the given layer to this view.
`void`	`addLink(Link link)` Adds the given link to this view.
`void`	`addProtocol(Protocol protocol)` Adds the given protocol to this view.
`void`	`addTransferUnit(TransferUnit unit, boolean recurse)` Adds a transfer unit to the view.
`boolean`	`equals(java.lang.Object o)` Mostly for unit testing purposes, does huge amounts of comparisons.
`java.util.List`	`getAvailableVariables(Layer layer)` Returns a list of all the available variables (those that have values longer than zero characters) on the specified layer.
`float`	`getEndTime()` Returns the end time of the network exchange data, as the timestamp of the last event included in the data, regardless of the type of event, layer etc.
`float`	`getEndTimeForLayer(Layer layer)` Returns the end time of the network exchange data for a particular layer, as the timestamp of the last event in the layer.
`Flow`	`getFlowById(long id)` Returns the flow by the given id, if any.
`java.util.List`	`getFlows()` Returns all the `flows` present in the scenario.
`Host`	`getHostById(long id)` Returns the host by the id.
`java.util.List`	`getHosts()` Returns all the `hosts` present in the scenario.
`Layer`	`getLayerById(long id)` Returns the layer with the given id.
`java.util.List`	`getLayers()` Returns all the layers present in the scenario, ordered from lower to higher.
`Link`	`getLinkById(long id)` Returns the link with the given id, if any.
`java.util.List`	`getLinks()` Returns a list of all the `links` in the scenario.
`protected java.util.List`	`getOrCreateUnitList(TransferUnit unit)` Gets the unit list for the layer of the specified unit, creates a new list if none exists.
`Protocol`	`getProtocolById(long id)` Returns the protocol with the given id, if any.
`java.util.List`	`getProtocols()` Returns all the protocols present.
`StepIterator`	`getStepIterator(Layer layer)` Returns an `iterator` for the steps on the specified layer.
`TransferUnit`	`getUnitById(long id)` Returns the transfer unit with the given id, if any.
`java.util.List`	`getUnitsForLayer(Layer layer)` Returns a sorted list of all the `units` in the given layer.
`java.util.List`	`getUnitsForLayer(Layer layer, float start, float end)` Returns a collection of all the `units` in the given layer between the given timestamps (inclusive).
`int`	`getValueMaxLength(VariableDefinition def)` Returns the maximum length of all the values of the given variable.
