  org.vrjuggler.vrjconfig.commoneditors.devicegraph.ConfigElementHolder
      org.vrjuggler.vrjconfig.commoneditors.devicegraph.ProxyInfo

public class ProxyInfo
extends ConfigElementHolder

A holder for ConfigElements that is used to provide run-time identification of a ConfigElement reference for a device proxy configuration. Proper use of this type is critical for proper handling of ConfigElement references held in a JGraph graph model.

Constructor Summary

ProxyInfo(ConfigElement proxyElt, ConfigContext ctx, List aliases)
Creates a new container for the given ConfigElement reference for a device proxy configuration.

Method Summary

boolean	acceptsSource(GraphModel model, Object edge, Object port) Verifies that the given port can be a source of the given edge within the given model.
boolean	acceptsTarget(GraphModel model, Object edge, Object port) Verifies that the given port can be a target of the given edge within the given model.
void	addAlias(ConfigElement aliasElt)
List	getAliases() Returns the list of aliases for the device proxy config element held by this object.

Constructor Detail

ProxyInfo

public ProxyInfo(ConfigElement proxyElt,
                 ConfigContext ctx,
                 List aliases)

Creates a new container for the given ConfigElement reference for a device proxy configuration.

Parameters:

proxyElt - the config element for the device proxy

ctx - the context in which proxyElt is active

aliases - the full list of aliases (instances of org.vrjuggler.jccl.config.ConfigElement) for proxyElt in ctx

Method Detail

acceptsSource

public boolean acceptsSource(GraphModel model,
                             Object edge,
                             Object port)

Verifies that the given port can be a source of the given edge within the given model. This determination is made by testing to see if the config element held by the parent of the target port (which must have parent containing a BaseDeviceInfo object) is of a type to which we are allowed to point.

Specified by:

acceptsSource in class ConfigElementHolder

acceptsTarget

public boolean acceptsTarget(GraphModel model,
                             Object edge,
                             Object port)

Verifies that the given port can be a target of the given edge within the given model. This determination is made by testing to see if the source port (which must contain a user object of type ProxyPointerInfo) is allowed to point at our vertex.

Specified by:

acceptsTarget in class ConfigElementHolder

getAliases

public List getAliases()

Returns the list of aliases for the device proxy config element held by this object. This will never return null.

Returns:

A non-null reference to a java.util.List instance. The list contains instances of org.vrjuggler.jccl.config.ConfigElement.

addAlias

public void addAlias(ConfigElement aliasElt)

removeAlias

public void removeAlias(ConfigElement aliasElt)
