# Class SyncProviderException

java.lang.Object
java.lang.Throwable
java.lang.Exception
java.sql.SQLException
javax.sql.rowset.spi.SyncProviderException

All Implemented Interfaces:
  `Serializable`, `Iterable<Throwable>`

public class SyncProviderException extends SQLException
Indicates an error with the `SyncProvider` mechanism. This exception is created by a `SyncProvider` abstract class extension if it encounters violations in reading from or writing to the originating data source.

If it is implemented to do so, the `SyncProvider` object may also create a `SyncResolver` object and either initialize the `SyncProviderException` object with it at construction time or set it with the `SyncProvider` object at a later time.

The method `acceptChanges` will throw this exception after the writer has finished checking for conflicts and has found one or more conflicts. An application may catch a `SyncProviderException` object and call its `getSyncResolver` method to get its `SyncResolver` object. See the code fragment in the interface comment for `SyncResolver` for an example. This `SyncResolver` object will mirror the `RowSet` object that generated the exception, except that it will contain only the values from the data source that are in conflict. All other values in the `SyncResolver` object will be `null`.

The `SyncResolver` object may be used to examine and resolve each conflict in a row and then go to the next row with a conflict to repeat the procedure.

A `SyncProviderException` object may or may not contain a description of the condition causing the exception. The inherited method `getMessage` may be called to retrieve the description if there is one.

## Constructor Details

### SyncProviderException

public SyncProviderException()
Creates a new `SyncProviderException` object without a detail message.

### SyncProviderException

public SyncProviderException(String msg)
Constructs a `SyncProviderException` object with the specified detail message.

Parameters:
  `msg` - the detail message

### SyncProviderException

public SyncProviderException(SyncResolver syncResolver)
Constructs a `SyncProviderException` object with the specified `SyncResolver` instance.

Parameters:
  `syncResolver` - the `SyncResolver` instance used to to process the synchronization conflicts
Throws:
  `IllegalArgumentException` - if the `SyncResolver` object is `null`.

## Method Details

### getSyncResolver

public SyncResolver getSyncResolver()
Retrieves the `SyncResolver` object that has been set for this `SyncProviderException` object, or if none has been set, an instance of the default `SyncResolver` implementation included in the reference implementation.

If a `SyncProviderException` object is thrown, an application may use this method to generate a `SyncResolver` object with which to resolve the conflict or conflicts that caused the exception to be thrown.

Returns:
  the `SyncResolver` object set for this `SyncProviderException` object or, if none has been set, an instance of the default `SyncResolver` implementation. In addition, the default `SyncResolver` implementation is also returned if the `SyncResolver()` or `SyncResolver(String)` constructors are used to instantiate the `SyncResolver` instance.

### setSyncResolver

public void setSyncResolver(SyncResolver syncResolver)
Sets the `SyncResolver` object for this `SyncProviderException` object to the one supplied. If the argument supplied is `null`, a call to the method `getSyncResolver` will return the default reference implementation of the `SyncResolver` interface.

Parameters:
  `syncResolver` - the `SyncResolver` object to be set; cannot be `null`
Throws:
  `IllegalArgumentException` - if the `SyncResolver` object is `null`.
