Member Function Documentation

__eq__()

bool SymEngine::HadamardProduct::__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 22 of file hadamard_product.cpp.

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

__hash__()

hash_t SymEngine::HadamardProduct::__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 13 of file hadamard_product.cpp.

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

accept() [1/2]

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

overridevirtual

Implements SymEngine::Basic.

accept() [2/2]

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

overridevirtual

Implements SymEngine::Basic.

compare()

int SymEngine::HadamardProduct::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 31 of file hadamard_product.cpp.

{
    SYMENGINE_ASSERT(is_a<HadamardProduct>(o));
    const HadamardProduct &other = down_cast<const HadamardProduct &>(o);
    return unified_compare(factors_, other.factors_);
}

get_args()

vec_basic SymEngine::HadamardProduct::get_args ( ) const

inlineoverridevirtual

Returns the list of arguments.

Implements SymEngine::Basic.

Definition at line 27 of file hadamard_product.h.

    {
        return vec_basic(factors_.begin(), factors_.end());
    }

inline
