Member Function Documentation

Check()

V8_INLINE void Check ( ) const

inline

Short-hand for ToChecked(), which doesn't return a value. To be used, where the actual value of the Maybe is not needed like Object::Set.

Definition at line 47 of file v8-maybe.h.

FromJust() [1/2]

V8_INLINE void FromJust ( ) &&

inline

Converts this Maybe<> to a value of type T. If this Maybe<> is nothing (empty), V8 will crash the process.

Definition at line 73 of file v8-maybe.h.

FromJust() [2/2]

V8_INLINE void FromJust ( ) const &

inline

Converts this Maybe<> to a value of type T. If this Maybe<> is nothing (empty), V8 will crash the process.

Definition at line 64 of file v8-maybe.h.

FromMaybe()

V8_INLINE void FromMaybe ( const void & default_value ) const

inline

Converts this Maybe<> to a value of type T, using a default value if this Maybe<> is nothing (empty).

Definition at line 82 of file v8-maybe.h.

IsJust() [1/2]

V8_INLINE bool IsJust ( ) const

inline

Definition at line 36 of file v8-maybe.h.

IsJust() [2/2]

V8_INLINE bool IsJust ( ) const

inline

Definition at line 134 of file v8-maybe.h.

References V8_INLINE.

IsNothing() [1/2]

V8_INLINE bool IsNothing ( ) const

inline

Definition at line 35 of file v8-maybe.h.

IsNothing() [2/2]

V8_INLINE bool IsNothing ( ) const

inline

Definition at line 133 of file v8-maybe.h.

References V8_INLINE.

operator!=() [1/2]

V8_INLINE bool operator!= ( const Maybe< void > & other ) const

inline

Definition at line 91 of file v8-maybe.h.

operator!=() [2/2]

V8_INLINE bool operator!= ( const Maybe< void > & other ) const

inline

Definition at line 140 of file v8-maybe.h.

References Maybe< T >::operator==(), and V8_INLINE.

operator==() [1/2]

V8_INLINE bool operator== ( const Maybe< void > & other ) const

inline

Definition at line 86 of file v8-maybe.h.

operator==() [2/2]

V8_INLINE bool operator== ( const Maybe< void > & other ) const

inline

Definition at line 136 of file v8-maybe.h.

References Maybe< T >::IsJust(), and V8_INLINE.

To()

V8_WARN_UNUSED_RESULT V8_INLINE bool To ( void * out ) const

inline

Converts this Maybe<> to a value of type T. If this Maybe<> is nothing (empty), |false| is returned and |out| is left untouched.

Definition at line 55 of file v8-maybe.h.

ToChecked()

V8_INLINE void ToChecked ( ) const

inline

An alias for |FromJust|. Will crash if the Maybe<> is nothing.

Definition at line 41 of file v8-maybe.h.
