template<typename ElementType>
class TMeshElementArrayBase

Remarks

This defines the container used to hold mesh elements. Its important properties are that it acts as an associative container (i.e. an element can be obtained from a given index), and that insert/delete/find are cheap. The current implementation is as a TSparseArray, but we abstract it so that this can be changed later if required, e.g. a TMap might be desirable if we wished to maintain unique indices for the lifetime of the container.

Variables

		Name	Description
	TSparseArray< E...	Container	The actual container, represented by a sparse array

Functions

		Name	Description
	void	Compact ( TSparseArray< int32 >& OutIndexRem... )	Compacts elements and returns a remapping table
	void	Remap ( const TSparseArray< int32 >& Index... )	Remaps elements according to the passed remapping table
