Member Function Documentation

◆ __eq__()

bool SymEngine::Piecewise::__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 154 of file logic.cpp.

155 {
156  return is_a<Piecewise>(o)
157  and unified_eq(get_vec(), down_cast<const Piecewise &>(o).get_vec());
158 }

◆ __hash__()

hash_t SymEngine::Piecewise::__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 129 of file logic.cpp.

130 {
131  hash_t seed = this->get_type_code();
132  for (auto &p : vec_) {
133  hash_combine<Basic>(seed, *p.first);
134  hash_combine<Basic>(seed, *p.second);
135  }
136  return seed;
137 }

Field Documentation

◆ type_code_id
