Member Function Documentation

__eq__()

bool SymEngine::Constant::__eq__ ( const Basic &  o ) const

overridevirtual

Parameters

o	- Object to be compared with

Returns

whether the 2 objects are equal

Implements SymEngine::Basic.

Definition at line 20 of file constants.cpp.

{
    if (is_a<Constant>(o))
        return name_ == down_cast<const Constant &>(o).name_;
    return false;
}

__hash__()

hash_t SymEngine::Constant::__hash__ ( ) const

overridevirtual

Returns

Size of the hash

Implements SymEngine::Basic.

Definition at line 13 of file constants.cpp.

{
    hash_t seed = SYMENGINE_CONSTANT;
    hash_combine<std::string>(seed, name_);
    return seed;
}

compare()

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

overridevirtual

Comparison operator

Parameters

o	- Object to be compared with

Returns

0 if equal, -1 , 1 according to string compare

Implements SymEngine::Basic.

Definition at line 27 of file constants.cpp.

{
    SYMENGINE_ASSERT(is_a<Constant>(o))
    const Constant &s = down_cast<const Constant &>(o);
    if (name_ == s.name_)
        return 0;
    return name_ < s.name_ ? -1 : 1;
}

get_name()
