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.

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.

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.

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_string(), and BitArray::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.

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.
