Properties
  NameDescription
Public propertyBuffer

(Inherited from SoCpuBufferObject.)
Public propertyIsDisposable

Remarks

This type of buffer efficiently represents a tile containing bitset data. The buffer can be used like any other buffer, but uses less memory when its contents are not actually being accessed.
