Detailed Description

template<typename T>
class Request::Key< std::vector< T > >

Vector key parser.

Parses a key and stores multiple values in a destination vector.

Parameters

T	type of value stored

Constructor & Destructor Documentation

template<typename T >

Request::Key< std::vector< T > >::Key ( std::string  name, Vector &  destination  )

inline

Constructor.

Parameters

name	key name
destination	reference to a vector where key values will be stored

Member Function Documentation

template<typename T >

virtual bool Request::Key< std::vector< T > >::isVector ( ) const

inlinevirtual

Tell whether the key takes more than one value.

A scalar key can take only one argument. If it is present multiple times in the request, only the last value will be used. A vector key takes multiple values : each occurence of the key in the request adds the correponding value to a list. In JSON-formatted requests, vector keys are associated to an array of values.

Returns

true if the key takes multiple values, false otherwise

Reimplemented from Request::KeyParserBase.

template<typename T >

virtual void Request::Key< std::vector< T > >::parse ( std::istream &  cin )

inlinevirtual

Parse an input stream and handle the key value.

Parse the key value in an input text stream and store it. This method is used for plain-text requests. Values associated to vector keys are appended to the list of previously read values.

Parameters

cin	input stream

Implements Request::KeyParserBase.

template<typename T >

virtual void Request::Key< std::vector< T > >::set ( const Json::Value &  json )

inlinevirtual

Retrieve the key value from a JSON value and handle it.

This method is used for JSON-formatted requests.

Parameters

json	JSON request

Implements Request::KeyParserBase.
