Member Function Documentation

__eq__()

bool SymEngine::Contains::__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 93 of file logic.cpp.

{
    return is_a<Contains>(o)
           and unified_eq(get_expr(), down_cast<const Contains &>(o).get_expr())
           and unified_eq(get_set(), down_cast<const Contains &>(o).get_set());
}

__hash__()

hash_t SymEngine::Contains::__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 67 of file logic.cpp.

{
    hash_t seed = SYMENGINE_CONTAINS;
    hash_combine<Basic>(seed, *expr_);
    hash_combine<Basic>(seed, *set_);
    return seed;
}

accept() [1/2]

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

overridevirtual

Implements SymEngine::Basic.

accept() [2/2]

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

overridevirtual

Implements SymEngine::Basic.

compare()

int SymEngine::Contains::compare ( const Basic &  o ) const

overridevirtual

Structural equality comparator.

Implements SymEngine::Basic.

Definition at line 100 of file logic.cpp.

{
    SYMENGINE_ASSERT(is_a<Contains>(o))
    const Contains &c = down_cast<const Contains &>(o);
    int cmp = unified_compare(get_expr(), c.get_expr());
    if (cmp != 0)
        return cmp;
    return unified_compare(get_set(), c.get_set());
}

}

get_args()

vec_basic SymEngine::Contains::get_args ( ) const
