Type is an allocation template. It consists of an Element and one or more dimensions. It describes only the layout of memory but does not allocate any storage for the data that is described.
A Type consists of several dimensions. Those are X, Y, Z, LOD (level of detail), Faces (faces of a cube map). The X,Y,Z dimensions can be assigned any positive integral value within the constraints of available memory. A single dimension allocation would have an X dimension of greater than zero while the Y and Z dimensions would be zero to indicate not present. In this regard an allocation of x=10, y=1 would be considered 2 dimensionsal while x=10, y=0 would be considered 1 dimensional.
The LOD and Faces dimensions are booleans to indicate present or not present.

destroy disconnects the object from the native object effectivly rendering this java object dead. The primary use is to force immediate cleanup of resources when its believed the GC will not respond quickly enough.
Return the total number of accessable cells in the Type.
Return the element associated with this Type.
Return the value of the Y dimension or 0 for a 1D allocation.
Return the value of the Z dimension or 0 for a 1D or 2D allocation.
Return if the Type has a mipmap chain.
setName assigns a name to an object. This object can later be looked up by this name. This name will also be retained if the object is written to an A3D file.

Called before the object's memory is reclaimed by the VM. This can only happen once the garbage collector has detected that the object is no longer reachable by any thread of the running application.
The method can be used to free system resources or perform other cleanup
before the object is garbage collected. The default implementation of the
method is empty, which is also expected by the VM, but subclasses can
override finalize() as required. Uncaught exceptions which are
thrown during the execution of this method cause it to terminate
immediately but are otherwise ignored.
Note that the VM does guarantee that finalize() is called at most
once for any object, but it doesn't guarantee when (if at all) finalize() will be called. For example, object B's finalize()
can delay the execution of object A's finalize() method and
therefore it can delay the reclamation of A's memory. To be safe, use a
ReferenceQueue, because it provides more control
over the way the VM deals with references during garbage collection.
