Detailed Description

template<typename T>
class OPTIONAL_XML_ATTRIBUTE< T >

Model an optional XML attribute.

This was implemented as an alternative to OPT. This class should be replaced with a simple typedef per type using std::optional when C++17 is published.

Definition at line 188 of file eagle_parser.h.

Constructor & Destructor Documentation

OPTIONAL_XML_ATTRIBUTE() [1/3]

template<typename T>

OPTIONAL_XML_ATTRIBUTE< T >::OPTIONAL_XML_ATTRIBUTE ( )

inline

Construct a default OPTIONAL_XML_ATTRIBUTE, whose data is not available.

Definition at line 201 of file eagle_parser.h.

 :
 m_isAvailable( false ),
 m_data( T() )
 {}

OPTIONAL_XML_ATTRIBUTE() [2/3]

template<typename T>

OPTIONAL_XML_ATTRIBUTE< T >::OPTIONAL_XML_ATTRIBUTE ( const wxString &  aData )

inline

Parameters

aData

is a wxString containing the value that should be converted to type T. If aData is empty, the attribute is understood as unavailable; otherwise, the conversion to T is tried.

Definition at line 211 of file eagle_parser.h.

 {
 m_data = T();
 m_isAvailable = !aData.IsEmpty();

 if( m_isAvailable )
 Set( aData );
 }

OPTIONAL_XML_ATTRIBUTE() [3/3]

template<typename T>

template<typename V = T>

OPTIONAL_XML_ATTRIBUTE< T >::OPTIONAL_XML_ATTRIBUTE ( T  aData )

inline

Parameters

aData

is the value of the XML attribute. If this constructor is called, the attribute is available.

Definition at line 225 of file eagle_parser.h.

 :
 m_isAvailable( true ),
 m_data( aData )
 {}

CGet()

template<typename T>

const T& OPTIONAL_XML_ATTRIBUTE< T >::CGet ( ) const

inline

Return a constant reference to the value of the attribute assuming it is available.

Returns

const T& - the value of the attribute.

operator *() [1/2]

template<typename T>

T& OPTIONAL_XML_ATTRIBUTE< T >::operator * ( )

inline

Return a reference to the value of the attribute assuming it is available.

Returns

T& - the value of the attribute.

Definition at line 314 of file eagle_parser.h.

 {
 return Get();
 }

operator *() [2/2]

template<typename T>

const T& OPTIONAL_XML_ATTRIBUTE< T >::operator * ( ) const

inline

Return a constant reference to the value of the attribute assuming it is available.

Returns

const T& - the value of the attribute.

Definition at line 324 of file eagle_parser.h.

 {
 return CGet();
 }

operator bool()

template<typename T>

OPTIONAL_XML_ATTRIBUTE< T >::operator bool ( ) const

inline

Returns

bool the availability of the attribute.

Definition at line 233 of file eagle_parser.h.

 {
 return m_isAvailable;
 }

operator->() [1/2]

template<typename T>

T* OPTIONAL_XML_ATTRIBUTE< T >::operator-> ( )

inline

Return a pointer to the value of the attribute assuming it is available.

Returns

T* - the value of the attribute.

Definition at line 334 of file eagle_parser.h.

 {
 return &Get();
 }

operator->() [2/2]

template<typename T>

const T* OPTIONAL_XML_ATTRIBUTE< T >::operator-> ( ) const

inline

Return a constant pointer to the value of the attribute assuming it is available.

Returns

const T* - the value of the attribute.

Definition at line 344 of file eagle_parser.h.

 {
 return &CGet();
 }

operator=() [1/2]

template<typename T>

OPTIONAL_XML_ATTRIBUTE<T>& OPTIONAL_XML_ATTRIBUTE< T >::operator= ( const wxString &  aData )

inline

Assign to a string (optionally) containing the data.

Parameters

aData

is a wxString that should be converted to T. If the string is empty, the attribute is set to unavailable.

Definition at line 244 of file eagle_parser.h.

 {
 m_isAvailable = !aData.IsEmpty();

 if( m_isAvailable )
 Set( aData );

 return *this;
 }

operator=() [2/2]

template<typename T>

OPTIONAL_XML_ATTRIBUTE<T>& OPTIONAL_XML_ATTRIBUTE< T >::operator= ( T  aData )

inline

Assign to an object of the base type containing the data.

Parameters

aData

is the actual value of the attribute. Calling this assignment, the attribute is automatically made available.

Definition at line 260 of file eagle_parser.h.

 {
 m_data = aData;
 m_isAvailable = true;

 return *this;
 }

operator==()

template<typename T>

bool OPTIONAL_XML_ATTRIBUTE< T >::operator== ( const T &  aOther ) const

Parameters

aOther

is the object of the base type that should be compared with this one.

 {
 return m_isAvailable && ( aOther == m_data );
 }

Set()

template<typename T>

void OPTIONAL_XML_ATTRIBUTE< T >::Set ( const wxString &  aString )

Parameters

aString

is the string that will be converted to the base type.

Definition at line 281 of file eagle_parser.h.

 {
 m_data = Convert<T>( aString );
 m_isAvailable = !aString.IsEmpty();
