Member Function Documentation

◆ __eq__()

bool SymEngine::UniversalSet::__eq__ ( const Basic &  o) const
overridevirtual

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 831 of file sets.cpp.

832{
833 if (is_a<UniversalSet>(o))
834 return true;
835 return false;
836}

◆ __hash__()

hash_t SymEngine::UniversalSet::__hash__ ( ) const
overridevirtual

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 825 of file sets.cpp.

826{
827 hash_t seed = SYMENGINE_UNIVERSALSET;
828 return seed;
829}

◆ accept() [1/2]

void SymEngine::UniversalSet::accept ( EvalRealDoubleVisitorFinal &  v) const
overridevirtual

Implements SymEngine::Basic.

◆ accept() [2/2]

void SymEngine::UniversalSet::accept ( Visitor &  v) const
overridevirtual

Implements SymEngine::Basic.

◆ compare()

int SymEngine::UniversalSet::compare ( const Basic &  o) const
overridevirtual

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.
