C++ (Cpp) function::gethash Examples

Example #1

File: remember.cpp Project: aaditya-thakkar/pynac

bool remember_table_entry::is_equal(function const & f) const
{
	GINAC_ASSERT(f.seq.size()==seq.size());
	if (f.gethash()!=hashvalue) return false;
	size_t num = seq.size();
	for (size_t i=0; i<num; ++i)
		if (!seq[i].is_equal(f.seq[i])) return false;
	++last_access = access_counter;
	++successful_hits;
	return true;
}

Example #2

File: remember.cpp Project: aaditya-thakkar/pynac

void remember_table::add_entry(function const & f, ex const & result)
{
	long entry = f.gethash() & (table_size-1);
	GINAC_ASSERT(entry<size());
	operator[](entry).add_entry(f,result);
}        

Example #3

File: remember.cpp Project: aaditya-thakkar/pynac

remember_table_entry::remember_table_entry(function const & f, ex  r)
  : hashvalue(f.gethash()), seq(f.seq), result(std::move(r))
{
	++last_access = access_counter;
	successful_hits = 0;
}

Example #4

File: remember.cpp Project: aaditya-thakkar/pynac

bool remember_table::lookup_entry(function const & f, ex & result) const
{
	long entry = f.gethash() & (table_size-1);
	GINAC_ASSERT(entry<size());
	return operator[](entry).lookup_entry(f,result);
