Constructor Detail

ProxyPointerInfo

public ProxyPointerInfo(ConfigElement elt,
                        ConfigContext ctx,
                        PropertyDefinition propDef)

Creates a new instance of the information object for a pointer to a device proxy. The pointer to the device proxy is described by the given property definition.

Parameters:

elt - the config element that is configured relative to a proxy

ctx - the context containing elt

propDef - the property definition that describes the property of elt that points at a device proxy

Method Detail

getPointerPropertyDefinition

public PropertyDefinition getPointerPropertyDefinition()

Returns the property definition that describes this object's pointer to a device proxy.

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 elmeent held by the parent of the target port (which must have parent containing a ProxyInfo object) is of a type at which we are allowed to point.

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 always returns false because a port for an element that points at a proxy cannot be a target for anything else.
