Constructors
Array
Array();
Creates an empty Array.
Destructor
~Array
virtual ~Array();
Destroys the Array.
Member Functions
add
template < typename T > Document & add(
T value
);
Creates an element with the name from the current pos and value and adds it to the array document.
The active document is returned to allow chaining of the add methods.
add
Document & add(
const char * value
);
Creates an element with a name from the current pos and value and adds it to the array document.
The active document is returned to allow chaining of the add methods.
get
template < typename T > T get(
std::size_t pos
) const;
Returns the element at the given index and tries to convert it to the template type. If the element is not found, a Poco::NotFoundException will be thrown. If the element cannot be converted a BadCastException will be thrown.
get
template < typename T > T get(
std::size_t pos,
const T & deflt
) const;
Returns the element at the given index and tries to convert it to the template type. If the element is not found, or has the wrong type, the deflt argument will be returned.
get
Element::Ptr get(
std::size_t pos
) const;
Returns the element at the given index. An empty element will be returned if the element is not found.
isType
template < typename T > bool isType(
std::size_t pos
) const;
Returns true if the type of the element equals the TypeId of ElementTrait, otherwise false.
toString
std::string toString(
int indent = 0
) const;
Returns a string representation of the Array.
