Platform::Collections::BackInsertIterator Class

Represents an iterator that inserts, rather than overwrites, elements into the back end of a sequential collection.

Syntax

template <typename T>  
class BackInsertIterator : 
public ::std::iterator<::std::output_iterator_tag, void, void, void, void>;  

Parameters

T
The type of item in the current collection.

Remarks

The BackInsertIterator class implements the rules required by the back_insert_iterator Class.

Members

Name Description
BackInsertIterator::BackInsertIterator Initializes a new instance of the BackInsertIterator class.

Public Operators

Name Description
BackInsertIterator::operator* Operator Retrieves a reference to the current BackInsertIterator.

BackInsertIterator::BackInsertIterator Constructor

Initializes a new instance of the BackInsertIterator class.

Syntax


explicit BackInsertIterator(  
   Windows::Foundation::Collections::IVector<T>^ v);  

Parameters

v
An IVector<T> object.

Remarks

A BackInsertIterator inserts elements after the last element of the object specified by parameter v.

BackInsertIterator::operator= Operator

Appends the specified object to the end of the current sequential collection.

Syntax

BackInsertIterator& operator=( const T& t);  

Parameters

t
The object to append to the current collection.

Return Value

A reference to the current BackInsertIterator.

BackInsertIterator::operator* Operator

Retrieves a reference to the current BackInsertIterator.

Syntax

BackInsertIterator& operator*();  

Return Value

A reference to the current BackInsertIterator.

Remarks

This operator returns a reference to the current BackInsertIterator; not to any element in the current collection.

BackInsertIterator::operator++ Operator

Returns a reference to the current BackInsertIterator. The iterator is unmodified.

Syntax


BackInsertIterator& operator++();  

BackInsertIterator operator++(int);  

Return Value

A reference to the current BackInsertIterator.

Remarks

By design, the first syntax example pre-increments the current BackInsertIterator, and the second syntax post-increments the current BackInsertIterator. The int type in the second syntax indicates a post-increment operation, not an actual integer operand.

However, this operator does not actually modify the BackInsertIterator. Instead, this operator returns a reference to the unmodified, current iterator. This is the same behavior as operator*.
