Detailed Description

template<class T>
class Arp::Base::Core::EnumDictionary< T >

The class implements an adapter for enums to define the string literals of the enum entries.

Template Parameters

T	The type of the enum.

This is a helper class to make enums parsable and loggable or formattable, respectively.

Constructor & Destructor Documentation

◆ EnumDictionary() [1/2]

template<class T >

Arp::Base::Core::EnumDictionary< T >::EnumDictionary ( const InitializerList & fields )

inline

Constructor passing the enum fields as initializer list.

Parameters

fields The enum fields as value string pairs.

◆ EnumDictionary() [2/2]

template<class T >

Arp::Base::Core::EnumDictionary< T >::EnumDictionary	(	const char *	invalidValueString,
		const InitializerList &	fields
	)

inline

Constructor passing the enum fields as initializer list.

Parameters

fields	The enum fields as value string pairs.
invalidValueString	A string which is used for formatting an invalid enum value.

Member Function Documentation

◆ GetEnumString()

template<class T >

const char * Arp::Base::Core::EnumDictionary< T >::GetEnumString ( T value ) const

inline

Returns the string of the specified enum entry.

Parameters

value The enum value of enum T to get the associated string from.

Returns: The string literal of the as argument passed enum value.

Exceptions

Exception If the as argument passed value is not defined in the enum.

◆ GetEnumValue()

template<class T >

T Arp::Base::Core::EnumDictionary< T >::GetEnumValue ( const char * fieldName ) const

inline

Returns the value of the specified enum string.

Parameters

fieldName The name of the enum field to get the associated string from.

Returns: The value of the as argument passed enum string.

Exceptions

Exception If the as argument passed field name is not defined in the enum.

◆ ReadEnumValue()

template<class T >

std::istream & Arp::Base::Core::EnumDictionary< T >::ReadEnumValue	(	std::istream &	is,
		T &	value
	)		const

inline

Tries to return the enum entry of the specified string.

Parameters

is	The stream to read the fieldName from to get the associated enum value.
value	The resulting enum value.

Returns: The as argument passed stream reference.

◆ TryGetEnumString()

template<class T >

bool Arp::Base::Core::EnumDictionary< T >::TryGetEnumString	(	T	value,
		const char *&	pResult
	)		const

inline

Returns the string of the specified enum value or nullptr if the value could not be found.

Parameters

value	The enum value of enum `T` to get the associated string from.
pResult	The string of the as argument passed enum value or `nullptr` if it could not be found.

Returns: true on success, otherwise false.

◆ TryGetEnumValue()

template<class T >

bool Arp::Base::Core::EnumDictionary< T >::TryGetEnumValue	(	const char *	fieldName,
		T &	value
	)		const

inline

Tries to get the enum value of the specified string.

Parameters

fieldName	The string to get the associated enum value from.
value	The resulting enum value.

Returns: true on success, otherwise false.

◆ WriteEnumString()

template<class T >

std::ostream & Arp::Base::Core::EnumDictionary< T >::WriteEnumString	(	std::ostream &	os,
		T	value
	)		const

inline

Writes the string of the specified enum value to the given stream.

Parameters

os	The stream to write the enum string to.
value	The enum value to write.

Returns: The as argument passed stream reference.

If the field name of the given enum value could not be found, the enum value is written as hex-string to the stream.
