Member Function Documentation

__eq__()

bool SymEngine::Xor::__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 418 of file logic.cpp.

{
    return is_a<Xor>(o)
           and unified_eq(container_,
                          down_cast<const Xor &>(o).get_container());
}

__hash__()

hash_t SymEngine::Xor::__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 404 of file logic.cpp.

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

accept() [1/2]

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

overridevirtual

Implements SymEngine::Basic.

accept() [2/2]

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

overridevirtual

Implements SymEngine::Basic.

compare()

int SymEngine::Xor::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 425 of file logic.cpp.

{
    SYMENGINE_ASSERT(is_a<Xor>(o))
    return unified_compare(container_,
                           down_cast<const Xor &>(o).get_container());
}

get_args()

vec_basic SymEngine::Xor::get_args ( ) const

overridevirtual

Returns the list of arguments.

Implements SymEngine::Basic.

Definition at line 412 of file logic.cpp.

{
    vec_basic v(container_.begin(), container_.end());
    return v;
}
