GCKMediaQueueItemBuilder Class

GCKMediaQueueItemBuilder Class Reference

Overview

A builder object for constructing new or derived GCKMediaQueueItem instances.

The builder may be used to derive a GCKMediaQueueItem from an existing one:

[[GCKMediaQueueItemBuilder alloc] initWithMediaQueueItem:originalItem];
builder.startTime = 10; // Change the start time.
builder.autoplay = NO; // Change the autoplay flag.
GCKMediaQueueItem *derivedItem = [builder build];

It can also be used to construct a new GCKMediaQueueItem from scratch:

builder.mediaInformation = ...;
builder.autoplay = ...;
// Set all other desired propreties...
GCKMediaQueueItem *newItem = [builder build];

Inherits NSObject.
