Member Function Documentation

__eq__()

bool SymEngine::ZeroMatrix::__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 16 of file zero_matrix.cpp.

{
    return (is_a<ZeroMatrix>(o)
            && m_->__eq__(*down_cast<const ZeroMatrix &>(o).m_)
            && n_->__eq__(*down_cast<const ZeroMatrix &>(o).n_));
}

__hash__()

hash_t SymEngine::ZeroMatrix::__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 8 of file zero_matrix.cpp.

{
    hash_t seed = SYMENGINE_ZEROMATRIX;
    hash_combine<Basic>(seed, *m_);
    hash_combine<Basic>(seed, *n_);
    return seed;
}

compare()

int SymEngine::ZeroMatrix::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 23 of file zero_matrix.cpp.

{
    SYMENGINE_ASSERT(is_a<ZeroMatrix>(o));
 
    const ZeroMatrix &other = down_cast<const ZeroMatrix &>(o);
    auto temp = m_->compare(*(other.m_));
    if (temp != 0) {
        return temp;
    } else {
        return n_->compare(*(other.n_));
    }
}
