Member Function Documentation

◆ eq()

bool SymEngine::Derivative::__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 2008 of file functions.cpp.

 {
     if (is_a<Derivative>(o)
         and eq(*arg_, *(down_cast<const Derivative &>(o).arg_))
         and unified_eq(x_, down_cast<const Derivative &>(o).x_))
         return true;
     return false;
 }

◆ hash()

hash_t SymEngine::Derivative::__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 1998 of file functions.cpp.

 {
     hash_t seed = SYMENGINE_DERIVATIVE;
     hash_combine<Basic>(seed, *arg_);
     for (auto &p : x_) {
         hash_combine<Basic>(seed, *p);
     }
     return seed;
 }

◆ compare()

int SymEngine::Derivative::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 2017 of file functions.cpp.

 {
     SYMENGINE_ASSERT(is_a<Derivative>(o))
     const Derivative &s = down_cast<const Derivative &>(o);
     int cmp = arg_->__cmp__(*(s.arg_));
     if (cmp != 0)
         return cmp;
     cmp = unified_compare(x_, s.x_);
     return cmp;
 }
