Constructor & Destructor Documentation

Member Function Documentation

◆ __eq__()

bool SymEngine::Xor::__eq__ ( const Basic o) const

Test equality.

A virtual function for testing the equality of two Basic objects

Use eq(const Basic &a, const Basic &b) non-member method
oa constant reference to object to test against
True if this is equal to o

Implements SymEngine::Basic.

Definition at line 418 of file logic.cpp.

420 return is_a<Xor>(o)
421 and unified_eq(container_,
422 down_cast<const Xor &>(o).get_container());

◆ __hash__()

hash_t SymEngine::Xor::__hash__ ( ) const

Calculates the hash of the given SymEngine class. Use Basic.hash() which gives a cached version of the hash.

64-bit integer value for the hash

Implements SymEngine::Basic.

Definition at line 404 of file logic.cpp.

406 hash_t seed = SYMENGINE_XOR;
407 for (const auto &a : container_)
408 hash_combine<Basic>(seed, *a);
409 return seed;

◆ accept() [1/2]

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

Implements SymEngine::Basic.

◆ accept() [2/2]

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

Implements SymEngine::Basic.

◆ compare()

int SymEngine::Xor::compare ( const Basic o) const

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.

427 SYMENGINE_ASSERT(is_a<Xor>(o))
428 return unified_compare(container_,
429 down_cast<const Xor &>(o).get_container());
int unified_compare(const T &a, const T &b)
Definition: dict.h:205

◆ get_args()

vec_basic SymEngine::Xor::get_args ( ) const

Returns the list of arguments.

Implements SymEngine::Basic.

Definition at line 412 of file logic.cpp.

414 vec_basic v(container_.begin(), container_.end());
415 return v;
T begin(T... args)
T end(T... args)

◆ get_container()

const vec_boolean & SymEngine::Xor::get_container ( ) const

Definition at line 453 of file logic.cpp.

455 return container_;

◆ is_canonical()

bool SymEngine::Xor::is_canonical ( const vec_boolean container_)
