collection_adapter (STL/CLR)
Wraps a .NET collection for use as an STL/CLR container. A collection_adapter is a template class that describes a simple STL/CLR container object. It wraps a Base Class Library (BCL) interface, and returns an iterator pair that you use to manipulate the controlled sequence.

Specializations
Specialization |

Members
Type Definition |
Description |
|---|---|
The type of a signed distance between two elements. |
|
The type of an iterator for the controlled sequence. |
|
The type of a dictionary key. |
|
The type of a dictionary value. |

Member Function |
Description |
|---|---|
Designates the wrapped BCL interface. |
|
Designates the beginning of the controlled sequence. |
|
Constructs an adapter object. |
|
Designates the end of the controlled sequence. |
|
Counts the number of elements. |
|
Swaps the contents of two containers. |
Operator |
Description |
|---|---|
Replaces the stored BCL handle. |
Remarks
You use this template class to manipulate a BCL container as a STL/CLR container. The collection_adapter stores a handle to a BCL interface, which in turn controls a sequence of elements. A collection_adapter object X returns a pair of input iterators X.begin() and X.end() that you use to visit the elements, in order. Some of the specializations also let you write X.size() to determine the length of the controlled sequence.
