Table of Contents
- $children : array<string|int, IMessagePart>
- $position : int
- __construct() : mixed
- add() : mixed
- Adds the passed IMessagePart to the container in the passed position.
- current() : mixed
- getChildren() : RecursiveIterator|null
- If the current element points to an IMultiPart, its child iterator is returned by calling {@see IMultiPart::getChildIterator()}.
- hasChildren() : bool
- Returns true if the current element is an IMultiPart and doesn't return null for {@see IMultiPart::getChildIterator()}. Note that the iterator may still be empty.
- key() : int
- next() : void
- offsetExists() : bool
- offsetGet() : mixed
- offsetSet() : void
- offsetUnset() : void
- remove() : int
- Removes the passed part, and returns the integer position it occupied.
- rewind() : void
- valid() : bool
Properties
$children
    protected
        array<string|int, IMessagePart>
    $children
    
    
        array of child parts of the IMultiPart object that is holding this container.
$position
    protected
        int
    $position
     = 0
    
        current key position within $children for iteration.
Methods
__construct()
    public
                    __construct([array<string|int, mixed> $children = [] ]) : mixed
        
        Parameters
- $children : array<string|int, mixed> = []
Return values
mixed —add()
Adds the passed IMessagePart to the container in the passed position.
    public
                    add(IMessagePart $part[, int $position = null ]) : mixed
        If position is not passed or null, the part is added to the end, as the last child in the container.
Parameters
- $part : IMessagePart
- 
                    The part to add 
- $position : int = null
- 
                    An optional index position (0-based) to add the child at. 
Return values
mixed —current()
    public
                    current() : mixed
        
    
    
        Return values
mixed —getChildren()
If the current element points to an IMultiPart, its child iterator is returned by calling {@see IMultiPart::getChildIterator()}.
    public
                    getChildren() : RecursiveIterator|null
    
    
    
        Return values
RecursiveIterator|null —the iterator
hasChildren()
Returns true if the current element is an IMultiPart and doesn't return null for {@see IMultiPart::getChildIterator()}. Note that the iterator may still be empty.
