Detailed Description

template<class T>
class rwsf::Enumeration< T >

rwsf::Enumeration holds a sequence of values of type T. The class provides a convenient interface for iterating over a variety of different container type implementations. All RWSF container implementations can be accessed through the rwsf::Enumeration interface.

Basic usage example:

Enumeration<std::string> namingBindings =
  rwsf::NamingContext::getGlobalInstance()->listBindings();
 
while (namingBindings.hasMoreElements()) {
  std::string bindingName = namingBindings.nextElement();
}

Constructor & Destructor Documentation

Enumeration() [1/2]

template<class T>

rwsf::Enumeration< T >::Enumeration

(

)

Creates an empty enumeration. Use the copy constructor to create a valid enumeration.

Enumeration() [2/2]

template<class T>

rwsf::Enumeration< T >::Enumeration

(

const Enumeration< T > &

rhs

)

Copy constructor. Attaches to and increments the reference count on the body instance of rhs.

~Enumeration()

template<class T>

virtual rwsf::Enumeration< T >::~Enumeration ( )

virtual

Detaches from the current body (if any), decrements its reference count, and deletes it if there are no other references.

Member Function Documentation

hasMoreElements()

template<class T>

bool rwsf::Enumeration< T >::hasMoreElements

(

)

const

Returns true if there are more elements in this enumeration, otherwise returns false.

nextElement()

template<class T>

T rwsf::Enumeration< T >::nextElement

(

)

Returns the next element if there are more elements, otherwise throws an rwsf::OutOfBoundsException("Invalid usage") exception.

operator=()

template<class T>

Enumeration< T > & rwsf::Enumeration< T >::operator=

(

const Enumeration< T > &

rhs

)

Assignment operator.
