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 36 of file checksumHashGenerator.I.

References add_int().

◆ add_fp() [1/2]

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 45 of file checksumHashGenerator.I.

References add_int().

◆ add_fp() [2/2]

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 54 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 28 of file checksumHashGenerator.I.

Referenced by add_bool(), add_fp(), add_pointer(), add_string(), BitArray::generate_hash(), and BitMask< uint32_t, 32 >::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 63 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 20 of file checksumHashGenerator.cxx.
