Constructor & Destructor Documentation

◆ Contains()

SymEngine::Contains::Contains ( const RCP< const Basic > &  expr,
const RCP< const Set > &  set 
)

Constructor.

Definition at line 64 of file logic.cpp.

65 : expr_{expr}, set_{set} {SYMENGINE_ASSIGN_TYPEID()}

Member Function Documentation

◆ __eq__()

bool SymEngine::Contains::__eq__ ( const Basic o) const
virtual

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
oa 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.

94{
95 return is_a<Contains>(o)
96 and unified_eq(get_expr(), down_cast<const Contains &>(o).get_expr())
97 and unified_eq(get_set(), down_cast<const Contains &>(o).get_set());
98}

◆ __hash__()

hash_t SymEngine::Contains::__hash__ ( ) const
virtual

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.

◆ accept() [1/2]

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

Implements SymEngine::Basic.

◆ accept() [2/2]

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

Implements SymEngine::Basic.

◆ compare()

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

Structural equality comparator.

Implements SymEngine::Basic.
