Member Function Documentation

◆ eq()

bool SymEngine::Naturals0::__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

o	a constant reference to object to test against

Returns: True if this is equal to o

Implements SymEngine::Basic.

Definition at line 751 of file sets.cpp.

{
    if (is_a<Naturals0>(o))
        return true;
    return false;
}

◆ hash()

hash_t SymEngine::Naturals0::__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 745 of file sets.cpp.

{
    hash_t seed = SYMENGINE_NATURALS0;
    return seed;
}

◆ accept() [1/2]

void SymEngine::Naturals0::accept ( EvalRealDoubleVisitorFinal & v ) const

overridevirtual

Implements SymEngine::Basic.

◆ accept() [2/2]

void SymEngine::Naturals0::accept ( Visitor & v ) const

overridevirtual

Implements SymEngine::Basic.

◆ compare()

int SymEngine::Naturals0::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.

Definition at line 758 of file sets.cpp.
