Detailed Description

Abstract base class for tables and views.

Note
This class may be inherited along different paths for some subclasses due to the diamond shaped inheritance hierarchy; thus, direct subclasses must inherit this class virtually.

overridedefault

Member Function Documentation

◆ add_column()

virtual Column * dd::Abstract_table::add_column ( )
pure virtual

◆ clone()

virtual Abstract_table * dd::Abstract_table::clone ( ) const
pure virtual

Allocate a new object graph and invoke the copy constructor for each object.

Returns
pointer to dynamically allocated copy

Implemented in dd::Table_impl, dd::View_impl, dd::Table, and dd::View.

◆ clone_dropped_object_placeholder()

virtual Abstract_table * dd::Abstract_table::clone_dropped_object_placeholder ( ) const
pure virtual

Allocate a new object which can serve as a placeholder for the original object in the Dictionary_client's dropped registry.

Such object has the same keys as the original but has no other info and as result occupies less memory.

Implemented in dd::Table_impl, dd::View_impl, dd::Table, and dd::View.

◆ columns() [1/2]

virtual const Column_collection & dd::Abstract_table::columns ( ) const

pure virtual

◆ set_options() [2/2]

virtual void dd::Abstract_table::set_schema_id ( Object_id  schema_id)
pure virtual

◆ type()

virtual enum_table_type dd::Abstract_table::type ( ) const
pure virtual

Implemented in dd::Table_impl, and dd::View_impl.

◆ update_aux_key()

virtual bool dd::Abstract_table::update_aux_key ( Aux_key ) const
inlinevirtual

Reimplemented in dd::Table_impl, and dd::Table.
