Interface MeshCache<T>

All Superinterfaces:

org.eclipse.emf.ecore.EObject, org.eclipse.emf.common.notify.Notifier

All Known Implementing Classes:

FXMeshCache, MeshCacheImpl, MeshCacheTest.TestCache, TestCache

public interface MeshCache<T>
extends org.eclipse.emf.ecore.EObject

A representation of the model object 'Mesh Cache'. A MeshCache is a central repository for data objects of type T, where T is a data object specific to the rendering engine associated with the cache. The cache will be responsible for creating and maintaining these objects. The MeshCache will supply references to them to Meshes on request, allowing multiple Meshes to draw from the same data object as a part of the Flyweight pattern.

Method Detail

getMesh

T getMesh(java.lang.String type)

Get the mesh for a given type, creating it if it does not already exist. It is assummed that all shapes of the type will make use of the same mesh, possibly transformed geometriclly, for rendering. For example, all shapes of type "RECTANGULAR_PRISM" might use the same eight pointed mesh, with each one distinguished by a differing position in three dimensional space or by changing its dimensions. The operation will return null for types which do not have such a prototypical mesh. In this case, getMesh(EEList) should be used instead.

getMesh

T getMesh(org.eclipse.emf.common.util.EList<Triangle> triangles)

Get the mesh specified by the given triangles, creating it if it does not already exist.
