Class SpannerExceptionFactory

java.lang.Object

com.google.cloud.spanner.SpannerExceptionFactory

public final class SpannerExceptionFactory
extends Object

A factory for creating instances of SpannerException and its subtypes. All creation of these exceptions is directed through the factory. This ensures that particular types of errors are always expressed as the same concrete exception type. For example, exceptions of type ErrorCode.ABORTED are always represented by AbortedException.

Method Detail

newSpannerException

public static SpannerException newSpannerException(ErrorCode code,
                                                   @Nullable
                                                   String message)

newSpannerException

public static SpannerException newSpannerException(ErrorCode code,
                                                   @Nullable
                                                   String message,
                                                   @Nullable
                                                   Throwable cause)

propagateInterrupt

public static SpannerException propagateInterrupt(InterruptedException e)

propagateTimeout

public static SpannerException propagateTimeout(TimeoutException e)

Transforms a TimeoutException to a SpannerException.

 
 try {
   Spanner spanner = SpannerOptions.getDefaultInstance();
   spanner
       .getDatabaseAdminClient()
       .createDatabase("[INSTANCE_ID]", "[DATABASE_ID]", [STATEMENTS])
       .get();
 } catch (TimeoutException e) {
   propagateTimeout(e);
 }
 
 

asSpannerException

public static SpannerException asSpannerException(Throwable t)

Converts the given Throwable to a SpannerException. If t is already a (subclass of a) SpannerException, t is returned unaltered. Otherwise, a new SpannerException is created with t as its cause.

newSpannerException

public static SpannerException newSpannerException(Throwable cause)

Creates a new exception based on cause.

Intended for internal library use; user code should use newSpannerException(ErrorCode, String) instead of this method.

newSpannerBatchUpdateException

public static SpannerBatchUpdateException newSpannerBatchUpdateException(ErrorCode code,
                                                                         String message,
                                                                         long[] updateCounts)

newAbortedDueToConcurrentModificationException

public static AbortedDueToConcurrentModificationException newAbortedDueToConcurrentModificationException(AbortedException cause)

Constructs a specific aborted exception that should only be thrown by a connection after an internal retry aborted due to concurrent modifications.

newAbortedDueToConcurrentModificationException

public static AbortedDueToConcurrentModificationException newAbortedDueToConcurrentModificationException(AbortedException cause,
                                                                                                         SpannerException databaseError)

Constructs a specific aborted exception that should only be thrown by a connection after an internal retry aborted because a database call caused an exception that did not happen during the original attempt.

newAbortedDueToConcurrentModificationException

public static AbortedDueToConcurrentModificationException newAbortedDueToConcurrentModificationException(AbortedDueToConcurrentModificationException cause)

Constructs a new AbortedDueToConcurrentModificationException that can be re-thrown for a transaction that had already been aborted, but that the client application tried to use for additional statements.

newSpannerException

public static SpannerException newSpannerException(@Nullable
                                                   io.grpc.Context context,
                                                   Throwable cause)

Creates a new exception based on cause. If cause indicates cancellation, context will be inspected to establish the type of cancellation.

Intended for internal library use; user code should use newSpannerException(ErrorCode, String) instead of this method.
