DISALLOW_COPY_AND_ASSIGN

#define DISALLOW_COPY_AND_ASSIGN

(

T

)

Value:

       T(T const&); \
       T& operator=(T const&)

Disable copy constructor and assignment operator.

If C++11 is supported, both copy and move constructors and assignment operators are deleted explicitly. Otherwise, they are only declared but not implemented. Place this macro in private section if C++11 is not available.

DMLC_IO_USE_LITTLE_ENDIAN

#define DMLC_IO_USE_LITTLE_ENDIAN   1

check for C++11 support

Use little endian for binary serialization if this is set to 0, use big endian.
