Member Function Documentation

◆ __eq__()

bool SymEngine::Union::__eq__ ( const Basic o) const
virtual

Test equality.

A virtual function for testing the equality of two Basic objects

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

Implements SymEngine::Basic.

Definition at line 889 of file sets.cpp.

890 {
891  if (is_a<Union>(o)) {
892  const Union &other = down_cast<const Union &>(o);
893  return unified_eq(container_, other.container_);
894  }
895  return false;
896 }

◆ __hash__()

hash_t SymEngine::Union::__hash__ ( ) const
virtual

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

Returns
64-bit integer value for the hash

Implements SymEngine::Basic.

Definition at line 881 of file sets.cpp.

882 {
883  hash_t seed = SYMENGINE_UNION;
884  for (const auto &a : container_)
885  hash_combine<Basic>(seed, *a);
886  return seed;
887 }

◆ compare()

int SymEngine::Union::compare ( const Basic o) const
virtual

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 913 of file sets.cpp.

914 {
915  SYMENGINE_ASSERT(is_a<Union>(o))
916  const Union &other = down_cast<const Union &>(o);
917  return unified_compare(container_, other.container_);
918 }
int unified_compare(const T &a, const T &b)
