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

◆ add_bool()

void ChecksumHashGenerator::add_bool ( bool flag)
inline

Adds a boolean flag.

Definition at line 35 of file checksumHashGenerator.I.

References add_int().

◆ add_fp() [1/2]

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 53 of file checksumHashGenerator.I.

References add_int().

◆ add_fp() [2/2]

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 44 of file checksumHashGenerator.I.

References add_int().

◆ add_int()

void ChecksumHashGenerator::add_int ( long sum)
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 27 of file checksumHashGenerator.I.

Referenced by add_bool(), add_fp(), add_fp(), add_pointer(), add_string(), BitArray::generate_hash(), and BitMask< WType, nbits >::generate_hash().

◆ add_pointer()

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 62 of file checksumHashGenerator.I.

References add_int().

◆ add_string()

void ChecksumHashGenerator::add_string ( const std::string & str)

Adds a string to the hash, by breaking it down into a sequence of integers.

Definition at line 19 of file checksumHashGenerator.cxx.
