Member Function Documentation

__eq__()

bool SymEngine::FiniteSet::__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 869 of file sets.cpp.

{
    if (is_a<FiniteSet>(o)) {
        const FiniteSet &other = down_cast<const FiniteSet &>(o);
        return unified_eq(container_, other.container_);
    }
    return false;
}

__hash__()

hash_t SymEngine::FiniteSet::__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 861 of file sets.cpp.

{
    hash_t seed = SYMENGINE_FINITESET;
    for (const auto &a : container_)
        hash_combine<Basic>(seed, *a);
    return seed;
}

compare()

int SymEngine::FiniteSet::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 878 of file sets.cpp.

{
    // compares two FiniteSet based on their length
    SYMENGINE_ASSERT(is_a<FiniteSet>(o))
    const FiniteSet &other = down_cast<const FiniteSet &>(o);
    return unified_compare(container_, other.container_);
}
