Package
Description
org.eclipse.gef.fx.anchors
This package provides a visual anchor abstraction ( `IAnchor`), a related abstract base implementation (`AbstractAnchor`), as well as concrete anchor implementations ( `StaticAnchor`, `DynamicAnchor`) to manage dynamic positioning of visuals in dependence of others.
org.eclipse.gef.fx.nodes
This package provides: an adaptation of an `IGeometry` to `Node`: `GeometryNode` a connection abstraction that is based on `IAnchor`: `Connection` a visual to display an image which is overlayed by another image on mouse hover: `HoverOverlayImageView` a visual providing a scrollable infinite canvas with a background grid: `InfiniteCanvas`

Class
Description
AbstractAnchor
`AbstractAnchor` is the abstract base implementation for `IAnchor`s.
AnchorKey
AnchorKey combines an anchored `Node` with a `String` qualifier to identify an anchor target.
IAnchor
An `IAnchor` is a visual anchor that will provide positions for attached `AnchorKey`s (i.e. anchored `Node`s) in local coordinates of the `AnchorKey`'s anchored `Node`.
IComputationStrategy
The `IComputationStrategy` is responsible for computing anchor positions based on the anchorage `Node`, the anchored `Node`, and respective (strategy-specific) `parameters`.
IComputationStrategy.Parameter
Base class for all computation parameters that can be passed to an `IComputationStrategy`.
IComputationStrategy.Parameter.Kind
Indicates whether the parameter value can be shared to compute positions of all attached anchors or not.
ProjectionStrategy
An `IComputationStrategy` that computes anchor position by projecting the respective anchored reference point to the outline of the anchorage reference geometry so that the respective point has minimal distance to the anchored reference point.

Description
AbstractAnchor
`AbstractAnchor` is the abstract base implementation for `IAnchor`s.
AnchorKey
AnchorKey combines an anchored `Node` with a `String` qualifier to identify an anchor target.
DynamicAnchor
The `DynamicAnchor` computes anchor positions through a `IComputationStrategy`.
IAnchor
An `IAnchor` is a visual anchor that will provide positions for attached `AnchorKey`s (i.e. anchored `Node`s) in local coordinates of the `AnchorKey`'s anchored `Node`.
StaticAnchor
An `StaticAnchor` provides a position for each `AnchorKey`, based on a reference position relative to the anchorage `Node`, to which the `StaticAnchor` is bound, or based on a (global) static reference position in case the `StaticAnchor` is unbound.
