Detailed Description

A hash value.

Hash values are used inside the MDL Core library to identify changes inside (re-)compiled material instances.

Constructor & Destructor Documentation

DAG_hash() [1/2]

mi::mdl::DAG_hash::DAG_hash ( )

inline

Default constructor.

DAG_hash() [2/2]

mi::mdl::DAG_hash::DAG_hash ( unsigned char const (&)  arr[16] )

inlineexplicit

Constructor from an array of 16 bytes.

Parameters

arr	an array of 16 bytes

Member Function Documentation

data() [1/2]

unsigned char * mi::mdl::DAG_hash::data ( )

inline

Access raw data.

Returns

a pointer to the raw 16 hash bytes

data() [2/2]

unsigned char const * mi::mdl::DAG_hash::data ( ) const

inline

Read-only access raw data.

Returns

a read-only pointer to the raw 16 hash bytes

operator!=()

bool mi::mdl::DAG_hash::operator!= ( DAG_hash const &  other ) const

inline

Compare two hashes for non-equality.

Parameters

other
