MediaPinList represents the elementary pins within a MediaSocket object.
This is a modifiable and indexable collection that exists only in the context of a MediaSocket and cannot be created separately from it, nor detached.
Adds a pin (elementary stream) to the collection.
- Parameters
-
| item | [in] A pointer to a MediaPin object that should be added to the collection. It is allowed to add a NULL item to the collection. Internally if the MediaPin object is not NULL it is retained by MediaPinList, so it is safe to release it after this method returns. |

Returns a pin (elementary stream) specified by index.
- Parameters
-
| itemIndex | The index of the elementary pin to be returned. Indexing starts from 0. |
- Returns
- A pointer to the MediaPin object specified by itemIndex.
The caller is not required to release the returned object.

Removes all pins from the collection.
When removed from the collection each MediaPin object is released.

Inserts a pin at the specified index.
- Parameters
-
| itemIndex | [in] The index in the collection where the new item shall be inserted. This must be a valid index in the collection. Indexing starts from 0. After the new item is inserted in the collection its index is the value of the itemIndex param. |
| item | [in] A pointer to the MediaPin object that shall be inserted. It is allowed to insert a NULL value in the collection. Internally the new item is retained (if not NULL), so it is safe to release it after this method returns. |
- Returns
- TRUE The item is inserted, FALSE otherwise.

| virtual bool_t remove |
( |
int32_t |
itemIndex | ) |
|
|
pure virtual |
Removes a pin (elementary stream) from the collection.
- Parameters
-
| itemIndex | [in] The index of the pin that should be removed from the collection. Indexing starts from 0. |
- Returns
- TRUE if the specified item is removed from the collection, otherwise FALSE.
When an MediaPin object is removed from the collection it is also released.

|
pure virtual |
Sets a new pin at the specified index.
- Parameters
-
| itemIndex | [in] The index in the collection where the new item shall be set. This must be a valid index in the collection. Indexing starts from 0. |
| item | [in] A pointer to the MediaPin object that shall be set. It is allowed to set a NULL value to the collection. Internally the new item is retained (if not NULL), so it is safe to release it after this method returns. The old item is released (if not NULL). |
- Returns
- TRUE The item is set, FALSE otherwise.
