Member Function Documentation

◆ __eq__()

bool SymEngine::EmptySet::__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 783 of file sets.cpp.

784{
785 if (is_a<EmptySet>(o))
786 return true;
787 return false;
788}

◆ __hash__()

hash_t SymEngine::EmptySet::__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 777 of file sets.cpp.

778{
779 hash_t seed = SYMENGINE_EMPTYSET;
780 return seed;
781}

◆ accept() [1/2]

virtual void SymEngine::EmptySet::accept ( EvalRealDoubleVisitorFinal v) const
virtual

Implements SymEngine::Basic.

◆ accept() [2/2]

virtual void SymEngine::EmptySet::accept ( Visitor v) const
virtual

Implements SymEngine::Basic.

◆ compare()

int SymEngine::EmptySet::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.
