        return type_name;
    }

GetSchema()

const string & duckdb::TypeExpression::GetSchema ( ) const

inline

                                    {
        return schema;
    }

GetCatalog()

const string & duckdb::TypeExpression::GetCatalog ( ) const

inline

                                     {
        return catalog;
    }

GetChildren() [1/2]

const vector< unique_ptr< ParsedExpression > > & duckdb::TypeExpression::GetChildren ( ) const

inline

                                                                    {
        return children;
    }

GetChildren() [2/2]

vector< unique_ptr< ParsedExpression > > & duckdb::TypeExpression::GetChildren ( )

inline

                                                        {

    }

ToString()

string duckdb::TypeExpression::ToString ( ) const

overridevirtual

Convert the Expression to a String.

Implements duckdb::BaseExpression.

Copy()

unique_ptr< ParsedExpression > duckdb::TypeExpression::Copy ( ) const

overridevirtual

Create a copy of this expression.

Implements duckdb::ParsedExpression.

Hash()

hash_t duckdb::TypeExpression::Hash ( ) const

overridevirtual

Creates a hash value of this expression. It is important that if two expressions are identical (i.e. Expression::Equals() returns true), that their hash value is identical as well.

Reimplemented from duckdb::ParsedExpression.

Serialize()

void duckdb::TypeExpression::Serialize ( Serializer &  serializer ) const

overridevirtual

Reimplemented from duckdb::ParsedExpression.

Verify()

void duckdb::TypeExpression::Verify ( ) const

overridevirtual

Reimplemented from duckdb::BaseExpression.
