Public Member Functions
void	PushFilter (const ColumnIndex &col_idx, unique_ptr< TableFilter > filter)
bool	Equals (TableFilterSet &other)
unique_ptr< TableFilterSet >	Copy () const
void	Serialize (Serializer &serializer) const

Static Public Member Functions
static bool	Equals (TableFilterSet *left, TableFilterSet *right)
static TableFilterSet	Deserialize (Deserializer &deserializer)

Public Attributes
map< idx_t, unique_ptr< TableFilter > >	filters

Detailed Description

The filters in here are non-composite (only need a single column to be evaluated) Conditions like A = 2 OR B = 4 are not pushed into a TableFilterSet.
