clone()

TupleElement* souffle::ram::TupleElement::clone ( ) const

inlineoverridevirtual

Create a clone (i.e.

deep copy) of this node

Implements souffle::ram::Expression.

equal()

bool souffle::ram::TupleElement::equal ( const Node &  ) const

inlineoverrideprotectedvirtual

Equality check for two RAM nodes.

Default action is that nothing needs to be checked.

getElement()

size_t souffle::ram::TupleElement::getElement ( ) const

inline

Get element.
