Detailed Description

Helper class for managing the Coin nodes of ViewProviderSketch.

Given the substantial amount of code involved in coin node management, EditModeCoinManager further delegates on other specialised helper classes. Some of them share the ViewProviderSketchCoinAttorney, which defines the maximum coupling and minimum encapsulation.

The most important such delegates are: EditModeGeometryCoinManager and EditModeConstraintCoinManager.

EditModeCoinManager takes over the responsibility of creating the Coin (Inventor) scenograph and modifying it, including all the drawing of geometry, constraints and overlay layer. This is an exclusive responsibility under the Single Responsibility Principle.

EditModeCoinManager exposes a public interface to be used by ViewProviderSketch. Where, EditModeCoinManager needs special access to facilities of ViewProviderSketch in order to fulfil its responsibility, this access is defined by ViewProviderSketchCoinAttorney.

EditModeCoinManager is responsible, under the Single Responsibility Principle, to manage the coin EditRoot node. This node is ref-ed on creation and unref-ed on destruction to ensure that its lifetime matches the one of EditModecoinManager.

EditRoot is added on request to pcRoot by ViewProviderSketch. The node pcRoot belongs, under the Single Responsibility Principle, to ViewProviderSketch. EditModeCoinManager delegates addition and removal of child notes of EditRoot to specialised helper classes.

EditModeCoinManager is designed to define the span of time in which ViewProviderSketch is in edit mode.

In addition to the scenograph, EditModeCoinManager is responsible for keeping any necessary mapping between indices used at ViewProviderSketch level, and internal indexing used by EditModeCoinManager and its subclasses.
