The latest version of this topic can be found at set::set (STL/CLR).

Constructs a container object.

Syntax

set();  
explicit set(key_compare^ pred);  
set(set<Key>% right);  
set(set<Key>^ right);  
template<typename InIter>  
    setset(InIter first, InIter last);  
template<typename InIter>  
    set(InIter first, InIter last,  
        key_compare^ pred);  
set(System::Collections::Generic::IEnumerable<GValue>^ right);  
set(System::Collections::Generic::IEnumerable<GValue>^ right,  
    key_compare^ pred);  

Parameters

first
Beginning of range to insert.

last
End of range to insert.

pred
Ordering predicate for the controlled sequence.

right
Object or range to insert.

Remarks

The constructor:

set();

initializes the controlled sequence with no elements, with the default ordering predicate key_compare(). You use it to specify an empty initial controlled sequence, with the default ordering predicate.

The constructor:

explicit set(key_compare^ pred);

initializes the controlled sequence with no elements, with the ordering predicate pred. You use it to specify an empty initial controlled sequence, with the specified ordering predicate.

The constructor:

set(set<Key>% right);

initializes the controlled sequence with the sequence [``right``.set::begin (STL/CLR)(), right``.set::end (STL/CLR)()), with the default ordering predicate. You use it to specify an initial controlled sequence that is a copy of the sequence controlled by the set object right, with the default ordering predicate.

The constructor:

set(set<Key>^ right);

initializes the controlled sequence with the sequence [``right``->set::begin (STL/CLR)(), right``->set::end (STL/CLR)()), with the default ordering predicate. You use it to specify an initial controlled sequence that is a copy of the sequence controlled by the set object right, with the default ordering predicate.

The constructor:

template<typename InIter>

set(InIter first, InIter last);

initializes the controlled sequence with the sequence [``first``, last``), with the default ordering predicate. You use it to make the controlled sequence a copy of another sequence, with the default ordering predicate.

The constructor:

template<typename InIter>

set(InIter first, InIter last,

key_compare^ pred);

initializes the controlled sequence with the sequence [``first``, last``), with the ordering predicate pred. You use it to make the controlled sequence a copy of another sequence, with the specified ordering predicate.

The constructor:

set(System::Collections::Generic::IEnumerable<Key>^ right);

initializes the controlled sequence with the sequence designated by the enumerator right, with the default ordering predicate. You use it to make the controlled sequence a copy of another sequence described by an enumerator, with the default ordering predicate.

The constructor:

set(System::Collections::Generic::IEnumerable<Key>^ right,

key_compare^ pred);

initializes the controlled sequence with the sequence designated by the enumerator right, with the ordering predicate pred. You use it to make the controlled sequence a copy of another sequence described by an enumerator, with the specified ordering predicate.
