Member Function Documentation

◆ __eq__()

bool SymEngine::Contains::__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 85 of file logic.cpp.

88  and unified_eq(get_expr(), down_cast<const Contains &>(o).get_expr())

Definition: logic.cpp:56

◆ __hash__()

hash_t SymEngine::Contains::__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 59 of file logic.cpp.

61  hash_t seed = SYMENGINE_CONTAINS;
62  hash_combine<Basic>(seed, *expr_);
63  hash_combine<Basic>(seed, *set_);
