ezProcessingStream Class Reference

A single stream in a stream group holding contiguous data of a given type. More...

#include <ProcessingStream.h>

Public Types

enum class  DataType : ezUInt8 {
  Half , Half2 , Half3 , Half4 ,
  Float , Float2 , Float3 , Float4 ,
  Byte , Byte2 , Byte3 , Byte4 ,
  Short , Short2 , Short3 , Short4 ,
  Int , Int2 , Int3 , Int4 ,
  Count
}
 The data types which can be stored in the stream. When adding new data types the GetDataTypeSize() of ezProcessingStream needs to be updated.
