to_reference_type() [1/2]

const reference_typet& to_reference_type ( const typet &  type )

inline

Cast a typet to a reference_typet.

This is an unchecked conversion. type must be known to be reference_typet. Will fail with a precondition violation if type doesn't match.

Parameters

type	Source type.

Returns

Object of type reference_typet.

Definition at line 148 of file pointer_expr.h.

to_reference_type() [2/2]

reference_typet& to_reference_type ( typet &  type )

inline

Cast a typet to a reference_typet.

This is an unchecked conversion. type must be known to be reference_typet. Will fail with a precondition violation if type doesn't match.

Parameters

type	Source type.

Returns

Object of type reference_typet.

to_writeable_object_expr() [1/2]

const writeable_object_exprt& to_writeable_object_expr ( const exprt &  expr )

inline

Cast an exprt to a writeable_object_exprt.

expr must be known to be writeable_object_exprt.

Parameters

expr must be known to be writeable_object_exprt.

Parameters

expr	Source expression

Returns

Object of type writeable_object_exprt
