    Returns:

    a ContentProviderOperation.Builder

  • newUpdate

    public static ContentProviderOperation.Builder newUpdate(Uri uri)

    Create a ContentProviderOperation.Builder suitable for building an update ContentProviderOperation.

    Parameters:

    uri - The Uri that is the target of the update.

    Returns:

    a ContentProviderOperation.Builder

  • newDelete

    public static ContentProviderOperation.Builder newDelete(Uri uri)

    Create a ContentProviderOperation.Builder suitable for building a delete ContentProviderOperation.

    Parameters:

    uri - The Uri that is the target of the delete.

    Returns:

    a ContentProviderOperation.Builder

  • newAssertQuery

    public static ContentProviderOperation.Builder newAssertQuery(Uri uri)

    Create a ContentProviderOperation.Builder suitable for building a ContentProviderOperation to assert a set of values as provided through ContentProviderOperation.Builder.withValues(ContentValues).

  • getUri

    public Uri getUri()

  • isYieldAllowed

    public boolean isYieldAllowed()

  • getType

    public int getType()

  • isWriteOperation

    public boolean isWriteOperation()

  • apply

    public ContentProviderResult apply(ContentProvider provider,
                              ContentProviderResult[] backRefs,
                              int numBackRefs)
                                throws OperationApplicationException

    Applies this operation using the given provider. The backRefs array is used to resolve any back references that were requested using ContentProviderOperation.Builder.withValueBackReferences(ContentValues) and ContentProviderOperation.Builder.withSelectionBackReference(int, int).

    Parameters:

    provider - the ContentProvider on which this batch is applied

    backRefs - a ContentProviderResult array that will be consulted to resolve any requested back references.

    numBackRefs - the number of valid results on the backRefs array.

    Returns:

    a ContentProviderResult that contains either the Uri of the inserted row if this was an insert otherwise the number of rows affected.

    Throws:

    OperationApplicationException - thrown if either the insert fails or if the number of rows affected didn't match the expected count

  • resolveValueBackReferences

    public ContentValues resolveValueBackReferences(ContentProviderResult[] backRefs,
                                           int numBackRefs)

    The ContentValues back references are represented as a ContentValues object where the key refers to a column and the value is an index of the back reference whose valued should be associated with the column.

    This is intended to be a private method but it is exposed for unit testing purposes

    Parameters:

    backRefs - an array of previous results

    numBackRefs - the number of valid previous results in backRefs

    Returns:

    the ContentValues that should be used in this operation application after expansion of back references. This can be called if either mValues or mValuesBackReferences is null

  • resolveSelectionArgsBackReferences

    public String[] resolveSelectionArgsBackReferences(ContentProviderResult[] backRefs,
                                              int numBackRefs)

    The Selection Arguments back references are represented as a Map of Integer->Integer where the key is an index into the selection argument array (see ContentProviderOperation.Builder.withSelection(java.lang.String, java.lang.String[])) and the value is the index of the previous result that should be used for that selection argument array slot.

    This is intended to be a private method but it is exposed for unit testing purposes

    Parameters:

    backRefs - an array of previous results

    numBackRefs - the number of valid previous results in backRefs

    Returns:

    the ContentValues that should be used in this operation application after expansion of back references. This can be called if either mValues or mValuesBackReferences is null

  • toString

    public String toString()

    Description copied from class: Object
    Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

       getClass().getName() + '@' + Integer.toHexString(hashCode())

    See Writing a useful toString method if you intend implementing your own toString method.

    Overrides:

    toString in class Object

    Returns:

    a printable representation of this object.

  • describeContents

    public int describeContents()

    Description copied from interface: Parcelable
    Describe the kinds of special objects contained in this Parcelable's marshalled representation.

    Specified by:

    describeContents in interface Parcelable

    Returns:

    a bitmask indicating the set of special object types marshalled by the Parcelable.
