Detailed Description

Helper class for resolving overloaded functions.

OFExplicitBool can be used to restrict an overloaded function's parameter to "real" OFBool values, e.g. pointers and numeric values can NOT be converted to OFExplicitBool implicitly.

Note

OFBool falls back to "int" on platforms that don't support the keyword "bool". Therefore the conversion of int values to OFExplicitBool can't be prevented on those platforms.

Constructor & Destructor Documentation

OFExplicitBool()

OFExplicitBool::OFExplicitBool ( explicit OFBool  value )

inline

Construct an OFExplicitBool object from an explicit OFBool value.

Parameters

value

either OFTrue or OFFalse.

Note

"explicit OFBool" is not a valid C++ type. It's just a term to explain the concept of OFExplicitBool, that is realized by SFINAE mechanisms in reality.

Member Function Documentation

operator OFBool()

OFExplicitBool::operator OFBool ( ) const

inline

Implicit conversion to OFBool.

This allows to use OFExplicitBool like a normal OFBool value, for example in if-statements.

operator!()

OFBool OFExplicitBool::operator! ( ) const

inline

Negation operator.

This allows to negate OFExplicitBool like a normal OFBool value, for example to use the negated value in if-statements.
