Member Function Documentation

◆ __eq__()

bool SymEngine::Tuple::__eq__ ( const Basic o) const

Test equality.

A virtual function for testing the equality of two Basic objects

Use eq(const Basic &a, const Basic &b) non-member method
oa constant reference to object to test against
True if this is equal to o

Implements SymEngine::Basic.

Definition at line 26 of file tuple.cpp.

27 {
28  if (is_a<Tuple>(o)) {
29  const Tuple &other = down_cast<const Tuple &>(o);
30  return unified_eq(container_, other.container_);
31  }
32  return false;
33 }

◆ __hash__()

hash_t SymEngine::Tuple::__hash__ ( ) const

Calculates the hash of the given SymEngine class. Use Basic.hash() which gives a cached version of the hash.

64-bit integer value for the hash

Implements SymEngine::Basic.

Definition at line 18 of file tuple.cpp.

19 {
20  hash_t seed = SYMENGINE_TUPLE;
21  for (const auto &a : container_)
22  hash_combine<Basic>(seed, *a);
23  return seed;
24 }

◆ compare()

int SymEngine::Tuple::compare ( const Basic o) const

Returns -1, 0, 1 for this < o, this == o, this > o. This method is used when you want to sort things like x+y+z into canonical order. This function assumes that o is the same type as this. Use __cmp__ if you want general comparison.

Implements SymEngine::Basic.

Definition at line 35 of file tuple.cpp.

36 {
37  SYMENGINE_ASSERT(is_a<Tuple>(o))
38  const Tuple &other = down_cast<const Tuple &>(o);
39  return unified_compare(container_, other.container_);

int unified_compare(const T &a, const T &b)
