Member Function Documentation

◆ hash()

hash_t SymEngine::UExprPoly::__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::UPolyBase< Cont, Poly >.
