Package com.google.common.util.concurrent

Class ExecutionError

java.lang.Object

java.lang.Throwable

java.lang.Error

com.google.common.util.concurrent.ExecutionError

All Implemented Interfaces:

Serializable

@GwtCompatible
public class ExecutionError
extends Error

Error variant of ExecutionException. As with ExecutionException, the error's cause comes from a failed task, possibly run in another thread. That cause should itself be an Error; if not, use ExecutionException or UncheckedExecutionException. This allows the client code to continue to distinguish between exceptions and errors, even when they come from other threads.

Since:

10.0

Constructor Detail

ExecutionError

@Deprecated
protected ExecutionError()

Deprecated.

Prefer ExecutionError(@org.checkerframework.checker.nullness.qual.Nullable java.lang.Error) a constructor that accepts a cause: Users of this class typically expect for instances to have a non-null cause. At the moment, you can usually still preserve behavior by passing an explicit null cause. Note, however, that passing an explicit null cause prevents anyone from calling Throwable.initCause(java.lang.Throwable) later, so it is not quite equivalent to using a constructor that omits the cause.

Creates a new instance with null as its detail message and no cause.

ExecutionError

@Deprecated
protected ExecutionError(@Nullable String message)

Deprecated.

Prefer ExecutionError(@org.checkerframework.checker.nullness.qual.Nullable java.lang.String,@org.checkerframework.checker.nullness.qual.Nullable java.lang.Error) a constructor that accepts a cause: Users of this class typically expect for instances to have a non-null cause. At the moment, you can usually still preserve behavior by passing an explicit null cause. Note, however, that passing an explicit null cause prevents anyone from calling Throwable.initCause(java.lang.Throwable) later, so it is not quite equivalent to using a constructor that omits the cause.

Creates a new instance with the given detail message and no cause.

ExecutionError

public ExecutionError(@Nullable String message,
                      @Nullable Error cause)

Creates a new instance with the given detail message and cause. Prefer to provide a non-nullable cause, as many users expect to find one.

ExecutionError

public ExecutionError(@Nullable Error cause)

Creates a new instance with null as its detail message and the given cause. Prefer to provide a non-nullable cause, as many users expect to find one.
