This class holds a number of models and can provide all of their parameters in getParameters. A custom model can easily be created that way:Creating a CompositeLabelModel
const compositeLabelModel = new CompositeLabelModel()
compositeLabelModel.labelModels.add(new ExteriorLabelModel())
compositeLabelModel.labelModels.add(new InteriorStretchLabelModel())

()
Creates a new instance of this label model with an empty labelModels collection.
Creates a default parameter that can be used for this model.
Remarks
If labelModels is not empty, the default parameter for the first model in that list is returned. Otherwise, the default parameter for createDefaultParameter is returned.
A parameter that is compatible with this model. Typically, this is a parameter that has been created by this model, and its property model returns this instance.
An IOrientedRectangle that describes the geometry of the label. This is typically designed as a flyweight, therefore clients should not cache the instance but store the values if they need a snapshot for later use.
Returns an instance that implements the given type or null.
Remarks
Typically, this method will be called in order to obtain a different view or aspect of the current instance. This is quite similar to casting or using a super type or interface of this instance, but is not limited to inheritance or compile time constraints. An instance implementing this method is not required to return non-null implementations for the types, nor does it have to return the same instance any time. Also it depends on the type and context whether the instance returned stays up to date or needs to be reobtained for subsequent use.
Type Parameters
T: any
Parameters
options - Object A map of options to pass to the method.
