Member Function Documentation

◆ __eq__()

bool SymEngine::Piecewise::__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 207 of file logic.cpp.

208 {
209  return is_a<Piecewise>(o)
210  and unified_eq(get_vec(), down_cast<const Piecewise &>(o).get_vec());
211 }

◆ __hash__()

hash_t SymEngine::Piecewise::__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 182 of file logic.cpp.

183 {
184  hash_t seed = this->get_type_code();
185  for (auto &p : vec_) {
186  hash_combine<Basic>(seed, *p.first);
187  hash_combine<Basic>(seed, *p.second);
188  }
189  return seed;
190 }
