Classes | Description

Contains classes to explore data returned through a content provider.



Cursor This interface provides random read-write access to the result set returned by a database query. 


AbstractCursor This is an abstract cursor class that handles a lot of the common code that all cursors need to deal with and is provided for convenience reasons. 
AbstractCursor.SelfContentObserver Cursors use this class to track changes others make to their URI. 
AbstractWindowedCursor A base class for Cursors that store their data in CursorWindows. 
CharArrayBuffer This is used for copyStringToBuffer(int, CharArrayBuffer)  
ContentObservable A specialization of Observable for ContentObserver that provides methods for invoking the various callback methods of ContentObserver. 
ContentObserver Receives call backs for changes to content. 
CursorJoiner Does a join on two cursors using the specified columns. 
CursorWindow A buffer containing multiple cursor rows. 
CursorWrapper Wrapper class for Cursor that delegates all calls to the actual cursor object  
DatabaseUtils Static utility methods for dealing with databases and Cursors. 
DatabaseUtils.InsertHelper This class allows users to do multiple inserts into a table but compile the SQL insert statement only once, which may increase performance. 
DataSetObservable A specialization of Observable for DataSetObserver that provides methods for invoking the various callback methods of DataSetObserver. 
DataSetObserver Receives call backs when a data set has been changed, or made invalid. 
MatrixCursor A mutable cursor implementation backed by an array of Objects. 
MatrixCursor.RowBuilder Builds a row, starting from the left-most column and adding one column value at a time. 
MergeCursor A convience class that lets you present an array of Cursors as a single linear Cursor. 
Observable<T> Provides methods for (un)registering arbitrary observers in an ArrayList. 


CursorJoiner.Result The result of a call to next().

SQLException An exception that indicates there was an error with SQL parsing or execution. 
StaleDataException This exception is thrown when a Cursor contains stale data and must be requeried before being used again.
