@Nullable
public static DrmInitData createSessionCreationData(@Nullable
                                                    DrmInitData manifestData,
                                                    @Nullable
                                                    DrmInitData mediaData)
```
    Merges DrmInitData obtained from a media manifest and a media stream.
    The result is generated as follows.
    1. Include all DrmInitData.SchemeDatas from manifestData where DrmInitData.SchemeData.hasData() is true.
    2. Include all DrmInitData.SchemeDatas in mediaData where DrmInitData.SchemeData.hasData() is true and for which we did not include an entry from the manifest targeting the same UUID.
    3. If available, the scheme type from the manifest is used. If not, the scheme type from the media is used.
    Parameters:
    
    manifestData - DRM session acquisition data obtained from the manifest.
    
    mediaData - DRM session acquisition data obtained from the media.
    
    Returns:
    
    A DrmInitData obtained from merging a media manifest and a media stream.
  - get
```
public DrmInitData.SchemeData get(int index)
```
    Retrieves the DrmInitData.SchemeData at a given index.
    
    Parameters:
    
    index - The index of the scheme to return. Must not exceed schemeDataCount.
    
    Returns:
    
    The DrmInitData.SchemeData at the specified index.
  - copyWithSchemeType
```
public DrmInitData copyWithSchemeType(@Nullable
                                      String schemeType)
```
    Returns a copy with the specified protection scheme type.
    
    Parameters:
    
    schemeType - A protection scheme type. May be null.
    
    Returns:
    
    A copy with the specified protection scheme type.
  - merge
```
public DrmInitData merge(DrmInitData drmInitData)
```
    Returns an instance containing the schemeDatas from both this and other. The schemeType of the instances being merged must either match, or at least one scheme type must be null.
    
    Parameters:
    
    drmInitData - The instance to merge.
    
    Returns:
    
    The merged result.
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(@Nullable
                      Object obj)
```
    Specified by:
    
    equals in interface Comparator<DrmInitData.SchemeData>
    
    Overrides:
    
    equals in class Object
  - compare
```
public int compare(DrmInitData.SchemeData first,
                   DrmInitData.SchemeData second)
```
    Specified by:
    
    compare in interface Comparator<DrmInitData.SchemeData>
  - describeContents
```
public int describeContents()
```
    Specified by:
    
    describeContents in interface Parcelable
  - writeToParcel
```
public void writeToParcel(Parcel dest,
                          int flags)
```
    Specified by:
    
    writeToParcel in interface Parcelable
