Constructor Detail

NavigableEffigy.Factory

public NavigableEffigy.Factory(CompositeEntity container,
                               java.lang.String name)
                        throws IllegalActionException,
                               NameDuplicationException

Create a factory with the given name and container.

Parameters:

container - The container.

name - The name.

Throws:

IllegalActionException - If the container is incompatible with this entity.

NameDuplicationException - If the name coincides with an entity already in the container.

Method Detail

canCreateBlankEffigy

public boolean canCreateBlankEffigy()

Return true, indicating that this effigy factory is capable of creating an effigy without a URL being specified.

Overrides:

canCreateBlankEffigy in class EffigyFactory

Returns:

True.

createEffigy

public Effigy createEffigy(CompositeEntity container,
                           java.net.URL base,
                           java.net.URL input)
                    throws java.lang.Exception

Create a new effigy in the given container by reading the input URL. If the input URL is null, then create a blank effigy. The blank effigy will have a new model associated with it. If this effigy factory contains an entity or an attribute named "blank", then the new model will be a clone of that object. Otherwise, it will be an instance of TypedCompositeActor. If the URL does not end with extension ".xml" or ".moml", then return null. If the URL points to an XML file that is not a MoML file, then also return null. The specified base is used to expand any relative file references within the URL.

Overrides:

createEffigy in class EffigyFactory

Parameters:

container - The container for the effigy.

base - The base for relative file references, or null if there are no relative file references.

input - The input URL.

Returns:

A new instance of PtolemyEffigy, or null if the URL does not specify a Ptolemy II model.

Throws:

java.lang.Exception - If the URL cannot be read, or if the data is malformed in some way.

modelIsValid

private boolean modelIsValid(NamedObj model)

checkFile

private boolean checkFile(java.net.URL url)

_newEffigy

protected NavigableEffigy _newEffigy(CompositeEntity container,
                                     java.lang.String name)
                              throws IllegalActionException,
                                     NameDuplicationException

Create a new effigy. We use the strategy pattern here so that derived classes can easily override the exact class that is created.

Parameters:

container - The container for the effigy.

name - The name.

Returns:

A new effigy.

Throws:

IllegalActionException

NameDuplicationException
