Detailed Description

This is a specific kind of HashGenerator that simply adds up all of the ints.

Nothing fancy, and pretty quick.

Member Function Documentation

void ChecksumHashGenerator::add_bool (  bool  flag  )  [inline]

Adds a boolean flag. Definition at line 49 of file checksumHashGenerator.I. References add_int(), and INLINE.

void ChecksumHashGenerator::add_fp (  double  num, double  threshold )  [inline]

Adds a floating-point number, first converting it to fixed point by dividing it by the indicated threshold. Definition at line 83 of file checksumHashGenerator.I.

void ChecksumHashGenerator::add_fp (  float  num, float  threshold )  [inline]

Adds a floating-point number, first converting it to fixed point by dividing it by the indicated threshold. Definition at line 66 of file checksumHashGenerator.I. References add_int(), and INLINE.

void ChecksumHashGenerator::add_int (  int  num  )  [inline]

Adds another integer to the hash so far. This function should be overridden in base classes; this is the principle implementation of the HashGenerator. Definition at line 36 of file checksumHashGenerator.I. References INLINE. Referenced by add_bool(), add_fp(), and BitMask< WordType, num_bits >::operator|().

void ChecksumHashGenerator::add_pointer (  void *  ptr  )  [inline]

Adds a pointer, derived simply by casting the pointer to an integer. This should be good enough even on architectures for which this cast is lossy. Definition at line 100 of file checksumHashGenerator.I.

void ChecksumHashGenerator::add_string (  const string &  str  )

Adds a string to the hash, by breaking it down into a sequence of integers. Definition at line 35 of file checksumHashGenerator.cxx.

size_t HashGeneratorBase::get_hash (   )  const [inline, inherited]

Returns the hash number generated. Definition at line 55 of file hashGeneratorBase.I.
