bool duckdb::ExpressionEqualityMatcher::Match ( Expression &  expr, vector< reference< Expression > > &  bindings  )

overridevirtual

Checks if the given expression matches this ExpressionMatcher. If it does, the expression is appended to the bindings list and true is returned. Otherwise, false is returned.
