Public methods

apply

Added in API level 5 
ContentProviderResult apply (ContentProvider provider, 
                ContentProviderResult[] backRefs, 
                int numBackRefs)

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

Parameters
provider ContentProvider: the ContentProvider on which this batch is applied
backRefs ContentProviderResult: a ContentProviderResult array that will be consulted to resolve any requested back references.
numBackRefs int: the number of valid results on the backRefs array.
Returns
ContentProviderResult 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

describeContents

Added in API level 5 
int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

resolveSelectionArgsBackReferences

Added in API level 5 
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 withSelection(String, 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 ContentProviderResult: an array of previous results
numBackRefs int: the number of valid previous results in backRefs
Returns
String[] 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

resolveValueBackReferences

Added in API level 5 
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 ContentProviderResult: an array of previous results
numBackRefs int: the number of valid previous results in backRefs
Returns
ContentValues 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

Added in API level 5 
String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: 

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

Returns
String a string representation of the object.

writeToParcel

Added in API level 5 
void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: The Parcel in which the object should be written.
flags int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
